Marshalls Guide to Laying Priora Permeable Paving
Guidelines For Installing Priora
The intended Priora area must fall away from the owner’s house and any other buildings in the immediate vicinity. If the driveway exceeds 20m in length and/or has a gradient greater than 1 in 100 then please contact Marshalls Technical Advisory Service.* The top surface of the driveway should finish at least 150mm below any adjoining wall DPC level.
If your house lies adjacent to or less than 600mm from the proposed Domestic Priora driveway area, establish depth of house foundation before undertaking any soil test/Priora installation. The house foundation top surface must be 600mm (minimum) below the finished level of the top of the proposed Priora driveway.
Soil Strength and Permeability
Marshalls Domestic Priora System must be laid on a subgrade which has previously had an established and adequate existing driveway and an area which has a subgrade soil strength greater than 5%. The Domestic Priora System is only suitable for soil areas where infiltration applies and the test criteria have been met as per the standard permeability test. For the standard permeability a test hole should be dug for every 20m2 of driveway. There should be a minimum of two holes. Holes/pits should be spaced evenly in relation to the proposed Priora area.*
Discharge onto Roadway
The Domestic Priora area must not discharge onto surrounding public roadway and pathways and towards any buildings.
Rainwater Catchment Area
No adjoining surface areas (rainwater pipes, roof areas, etc) must drain onto and into the proposed Domestic Priora driveway area, however, small areas such as door steps and garage areas are acceptable providing they do not exceed 5% of the driveway area. Guideline: Catchment area **= driveway area **Catchment area = drained surface area
Priora must be laid with 20mm and 6mm clean crushed stone aggregate to BS EN13242 and BS EN12620 to ensure compliance. Priora must be laid with 20mm and 6mm clean crushed stone aggregate to BS EN13242 and BS EN12620 to ensure compliance. When installing in close proximity to existing trees, tree roots smaller than 25mm diameter may be pruned back, preferably to a side branch, using a suitable pair of secateurs or hand saw. Roots larger than 25mm should only be severed following consultation with an arboriculturist, as they may be essential to the tree’s health and stability. Protection of the pavement will also be required, hence the requirement of a permeable root barrier systemr which is non surface protruding, and therefore, does not present a trip hazard once installed.
Health and Safety
It is possible that more excavation for a Priora driveway may be required than that of a driveway constructed of traditional block paving, therefore, care must be taken when excavating ground to a deeper level. Particular care must be taken to protect the sites from children and partially sighted persons and for collapse of adjoining features such as boundary walls/fences.
Check for services, if they run through intended Priora areas, the service provider must be consulted before work commences. Care must be taken when constructing over sewer, rainwater pipes and water pipes to ensure that the services remain supported for their full length by undisturbed material and are surrounded on the remaining sides by a minimum of 150mm of 6mm material to protect the service.
Go Green! Building an Environmentally friendly Driveway
When I think of old gravel driveways, I used to think of potholes, ruts and mud, but now there’s an easy Green solution for driveways! Before EcoGrid was invented if you parked your car on grass it meant you would soon have a muddy mess. Now there’s a simple way to fix up mud issues and park your car on a green lawn – without damaging the look.
Imagine a place where those big black parking lots were gone – and you park on grass. Green parking lots, green driveways! EcoGrid is a fantastic new product that allows grass to grow – and lets you park on it! Because it supports and spreads out the weight of your car – there are no more ruts and the water flows into the ground. This virtually eliminates mud… and it can be used with gravel too. There are many examples of this permeable paving grid that create green parking lots, gravel driveways, and even horse paddocks!
There are many new products available that can directly impact the environment – in a good way – and products like EcoGrid is one such an invention. In the world where parking lots and driveways are a standard feature – there are a lot of new innovations like the EcoGrid called permeable paving. Yes, there is an asphalt alternative! Cement will crack and heave….so why not look at some green, driveable product that will last for decades?
I’m an expert on green driveways – with gravel or grass – and have helped people build parking areas and green driveways around the UK. I spend part of my day with architects and homeowners – figuring out ways to “Build Green”! Last year there were thousands of driveways built across the UK using Ecogrid with thyme, sedums and of course grass.
5 Great Reasons to build a Green Driveway!
Does it really help the Environment?
Permeable paving is the term frequently used for systems like Ecogrid – which allow water to drain or permeate into your base. In the past, asphalt was the top choice for driveways because it was simple and cheap to install. Putting in a plastic grid system is slightly more expensive but here are some of the benefits:
1. Recycled Plastic turns into an environmentally neutral product. EcoGrid is 100% recycled plastic – and will outlast any asphalt driveway. It won’t crack and rarely needs repairs even after decades of use. The plastic used in Ecogrid is environmentally neutral – so it won’t deteriorate and leech into your soil. It is UV resistant, frost neutral and can withstand the heat.
2. Storm Water Control – when it rains or pours the water carries the pollutants from a car straight into most drains. These drains often feed directly into the lakes and streams. When water can flow into the soil it will become naturally filtered.
3. Mud Control! – When water is kept draining (thanks gravity!) it will seep into the sub-base and help control mud. Gravel driveways used to form muddy spots and potholes – but by using a grid system the water flows away from the surface. No more mud!
4. Cost Savings Grid systems originally cost more than asphalt and less than concrete or stone pavers. In the long term the savings are huge – not just for the environment but for the wallet. Grids will keep the gravel from disappearing – and slow down the migration of gravel. They prevent washouts and stop pot holes. Grid systems installed across Europe typically last over 20-30 years, with little to no maintenance or repairs.
5. Creating Green Space
These Ecogrid systems are so easy to install that they frequently get used for extra parking. If you ever need an extra parking place – don’t park on your lawn – install an area for your bikes, cars or trailers – in just a day. They can be used to help control mud and erosion, and give your family a space that is green instead of a slab of concrete!
There’s 2 common options when using grid – planting grass and using gravel. This section is about using grass – which is what I’ve used around my father’s house. Dad has a garden area that really has some wet drainage issues so we wanted to stop the mud from forming and keep the grass. Using grid was a fantastic option!
This EcoGrid has been used all over Europe for over 20 years, and it’s a heavy industrial plastic that’s been engineered to withstand huge loads – cars, motorhomes, trucks and even firetrucks! The concept behind it is brilliant – and so simple
These squares of recycled plastic (100% recycled too!) – are from 30mm – 50mm thick. The e40 – which is what I personally have used around my father’s house – is Ecogrid’s mid weight product for residential driveways. At 40mm deep it really doesn’t sound like much until you realize how simple and easy it works. The plastic won’t shift, split or crack even when cars park on it. It really does work like a snowshoe – spreading out the weight of car tyres – and distributing the load. Because it has so much empty space – the grass grows and the grid doesn’t show any more.
Grass can be planted or seeded and the roots get protected by the grid. After rain, the Ecogrid allow water to gradually absorb into the soil below. To me, this is really the perfect solution for someone who needs an extra parking space but doesn’t want to put down more tar or cement. It’s great for visitor parking too… and if we had a camper van or a motorhome – this would be perfect.
For the grass area we had to do some excavation – basically to get rid of the old grass in the yard. Ecogrid suggested a huge amount of sand get mixed in with the soil. The sand keeps the water draining away from the surface – and into the sub-base. What was interesting was the sub-base only needed to be about 4 inches deep – made of the sand and soil. We topped it off, and threw down a bit of seed, and waited for it to grow. Alas – it still has to be cut!

Designing a Greener City: Green Driveway Ideas
Sustainability has become a primary concern for many people as they start to look at making home improvements. If you need a new driveway, you may be concerned about the effects of paving over such a large area. Pavement prevents rainwater from soaking into the ground where it can benefit plants and enter the groundwater system. It can also result in future stresses on landfills as driveways are torn up and replaced. The following are a few green driveway options that you can prevent these issues and create a greener driveway.
Opt for permeable paving
Permeable paving gives you the benefit of a firm surface to park and drive your car upon, while also allowing water to soak through and into the soil. There are several permeable options:
Solid paving – this looks like regular paving except there are small joints between the cement tiles. Beneath these tiles is a plastic grid that allows water to trickle through these joints and into the soil below.
Green paving – green paving consists of pavers that have an open grid design. Once installed, grass or other durable plants are grown inside the grids. Water can drain through and the grass cuts down on the heat sink effect of the paving.
Porous paving – this asphalt product looks just like traditional asphalt, but it has a more porous mixture that allows moisture to soak through.
Consider gravel curbing
Runoff from the driveway is another concern. You don’t want water to sit on the driveway and cause damage, but you also don’t want it running into the street to be lost to evaporation. Installing a deep gravel border on either side of the paved driveway can solve this issue.
This method requires that the driveway is constructed to have a gentle grade on either side from the center, similar to how roadways are built. Then, a deep gravel-filled trench is used to curb either side of the driveway. Ideas for planting along a driveway include plants that grow well in gravel, like lavender, ornamental grasses and yucca, can be added for additional beauty.
Combine different materials
A combination of different materials works exceptionally well in long driveways designs because it helps add a more distinct look to the site.
One popular way from the past that is making a comeback is to only pave the “tire treads” of the driveway, leaving the area in the center planted with grass or low-growing plants. Concrete or paving stones can be used for the solid surface, while the center can be left with only plants or you can use permeable paving.
Another option is to integrate gravel joints into a concrete driveway. These consist of trenches in the concrete that are filled with gravel, usually along the borders of the drive or cutting across it at intervals. Colorful gravel can be used to create an interesting design.
Make the most of what you have
There’s no need to tear up a driveway just because it currently looks bad. Sometimes the greener option is to repair what you have, using an asphalt coating or other option.
For asphalt paving, having it sealcoated every two or three years gives it the appearance of a new surface and it also prolongs the life of the asphalt. If there is extensive cracking and damage, have the cracks filled and then schedule a resurfacing. This is where a thicker layer of fresh asphalt is applied over the old, making the driveway look like new. You can even opt for coloured asphalt to add to the visual appeal.
Concrete can be sealed against water damage, which prolongs its life. If the concrete is badly stained, consider having it painted or acid-dyed instead of replaced. When major damage is the concern, the driveway can be broken up and recycled into permeable pavers instead of carted to the landfill.
Choosing surfaces for driveways that are green and sustainable isn’t just an environmental choice. It also provides you with more aesthetic choices so that the driveway becomes an extension of your home’s landscaping.
Concrete Driveway Repair & Leveling
If you have uneven or sunken sections of your driveway, you’ve got options other than tearing it out and replacing it. This article will show you how A-1 Concrete Leveling can raise and level your driveway at significant cost savings, as well as minimal downtime.
A-1 Concrete Leveling lifts and levels driveways using our environmentally friendly limestone grout. This creates a rock-solid base that keeps the drive level and safe for years to come.

The Basics of Concrete Driveway Repair
Concrete driveway slabs can present a variety of problems due to soil settling, ground water issues, rodent burrowing and more. And, even though concrete is one of the most durable construction materials there is, without proper maintenance or repair, it will deteriorate over time.
When you are trying to decide whether to repair, or replace your uneven concrete driveway, we want to help you make an educated descision on your best options.
Repairing Concrete Driveways
As much as we like to think Earth is an immovable object and our homes and driveways will remain the way they are forever, that’s just not reality. Driveway slabs sink for a number of reasons, but primarily it’s due to water. Water can create voids under the driveways slabs, causing it to sink over time.
It is important for you to find a concrete driveway leveling expert who will not only level your concrete back to where it should be, but also offer solutions to the cause of your sunken concrete issues. This will often involve fixing downspout drains, or caulking cracks or joints in your driveway. During any assesment from a leveling professional, be sure to ask what they would recommend to keep the issue from happening again. This is the only way to ensure you have beautiful, safe, concrete for years to come.

Driveway Crack Repair
Driveways can crack along joints and cut lines, but can also crack following random paths across the concrete driveway slabs. All of these cracks are not only ugly, but they can also cause safety concerns when the broken slabs heave or settle thereby creating trip hazzards.
- Driveway Sealing and Caulking: Properly sealing your concrete driveway and caulking the cracks, greatly reduces water’s ability to penetrate the concrete’s surface and flow under the slab. This dramatically increases the beauty, and lifespan of your concrete driveway. This process starts with pressure washing the surface to lift and remove contaminants and surface stains before applying a sealant. Then, the cracks in the concrete are caulked with long-lasting caulk to prevent water from penetrating within and beneath the concrete. This lessens the impact of the freeze/thaw process and, along with sealing, is an important step to maintain the integrity of your concrete.

- Driveway Leveling: In many cases, a crack within a slab, or a joint between slabs, may allow part of a concrete slab to become uneven. Fortunately, concrete driveway leveling can be used to pump material under the lower portion of the slab, to raise it up flush with the other side many times closing the crack in the process. This can eliminate trip hazards while avoiding a long, grueling, and expensive replacement project.

Concrete Driveway Repair Methods
There are several different ways to repair a sunken, uneven concrete driveway. These include tearing it out and replacing it; mechanically lifting the concrete slabs with some kind of jack system or front-end loader, then filling underneath to keep from settling again; to pumping material under the slab, lifting it hydraulically, and filling in any voids at the same time. All of these options have pros and cons and variations within them.
A-1 Concrete Leveling focuses primarily on the last method. We typically drill small holes in the concrete, then pump a material underneath them and gently lift the concrete back into place. This method is typically much faster than the other options, and less expensive as well. It has the added benefit of creating a compact foundation for your concrete, solving many issues that caused the driveway to sink in the first place.
Concrete Driveway Leveling
The concrete driveway leveling process while simple isn’t easy. Our expert technicians have all worked for years honing their craft so they can repair your driveway and bring it back so it’s level and beautiful. We start by drilling a small, one-inch hole in the concrete at strategic locations. Then, using our patented equipment our leveling professionals pump material beneath the slab gently lifting it into place. Our process allows for precise control, so we are able to stop the lift at just the right time. We then fill the holes with a non-shrink, color-matching grout. Finally, the driveway is cleaned off and we leave your concrete looking beautiful and better than it’s looked in years.

Uneven Concrete Driveway Causes
Driveways can sink for a number of reasons, but most of the time water is the culprit. During our free evaluations, we will almost always find the causes pretty quickly. Oftentimes we’ll find downspouts that are pouring water onto, or beside the driveway. Another common issue is poorly filled and compacted soil next to the garage foundation. Some builders will even use this area to bury some of the debris from building the house. When A-1 discovers the causes, we will know just what to recommend to fix the uneven concrete, while offering suggestions on how to minimize any issues in the future.

Concrete Driveway Leveling Examples
A-1 levels dozens of driveways every week across our nationwide locations. Take a look at some examples below of before and after photos to get a sense of what we can accomplish.
Concrete Driveway Leveling and Repair
The second most common area we level are driveways, and one of the issues we most often see is driveways sinking at the apron where they meet the garage. This is often due to poor backfill around the garage footer when it was built.
The concrete driveway apron is down pretty much the same all the way across. This is a perfect example of a situation where the ground fill around the garage foundation wasn’t filled and compacted correctly.
A-1 was able to bring the driveway back up to level across the entire length of the garage. We also used a flexible caulk to fill in the joints between the drive and garage to keep water from getting under the slab and causing more damage down the road.
Driveways can get uneven for many different reasons. Some will have slabs that seem to move independently of each other even in the middle of the drive. A-1 can level these slabs and bring them all even with each other.
Even concrete slabs like this can be leveled and made even with one another. Even slabs that appear to be lifted can sometimes be lowered on one side by raising the other side of the same slab.
Working around the concrete slabs, strategically, our exert technicians can even up even the most out-of-level driveways.

Concrete Driveway Leveling Costs
Looking at what can be a large expanse of concrete, may make you think it’s going to be too expensive to repair your out-of-level concrete driveway, but fixing your driveway doesn’t have to break the bank. In fact, our repair process can oftentimes cost up to 70% less than the cost of replacing it. While we can’t give you exact costs, you can rest assured that you aren’t going to find a better value when it comes to concrete leveling for your driveway. But, you don’t have to take our word for it. Contact us today for your Free Estimate so you can find out just how affordably you can get your driveway repaired.
Professional Concrete Driveway Leveling vs. DIY
Leveling a concrete driveway as a do it yourselfer, for the most part, isn’t an option. Even if you had all the right equipment, you’d still be missing out on the most important consideration, and that’s the expertise it takes to do the job right. Professional concrete repair technicians have years of experience and know exactly where to lift, and how much they can push a driveway slab. Concrete reacts a certain way when you exert pressure to it. It can crack, or shift farther than you expect it to. Or collapse mere weeks after you do the job if it’s not properly supported. There is much in life you can do yourself around the house, but concrete driveway repair and leveling is really something best left to the concrete leveling professionals.
Concrete Driveway Leveling vs. Mudjacking
The terms “concrete driveway leveling” and “driveway mudjacking” are often used interchangeably, but they can actually mean two different processes.
Driveway Mudjacking typically uses one of a few different mixtures consisting of topsoil, water, and sand or cement and often requires far larger holes to be drilled (up to 3 inches in diameter).
A-1’s concrete driveway leveling process, by comparison, is a much faster and lower-impact process that uses a pulverized limestone slurry that offers far more compressive strength and only requires a 1-inch hole.
Choosing Concrete Driveway Repair Contractors
We hope by now you are seeing the value in choosing a professional concrete leveling technician for your driveway repair project. The next question you probably have is how to choose the right company for your job? Be sure to look at how long they’ve been in business. Definitely check out their reviews online. Do they seem to only push you in one direction without considering other options, like when should foam leveling be used vs. stone slurry grout? There is no one size fits all answer, so be sure to keep that in mind when talking to concrete leveling contractors. They should know the best practices and be able to articulate why one approach is better for your particular concrete driveway leveling project.

How To Lay Crazy Paving
Brought to you by
There are many hard surface options to choose from but I like crazy paving – it’s also called random paving.
It’s a bit like putting a jigsaw together and it looks great.
Here’s how to do it!
1. Crazy paving is usually laid on a hard surface like concrete, but you can lay it on a soft, level surface.
You can put it over a compacted road base and use a 40 to 50 mm thick stone, but the thickness of stone will depend on the amount and weight of traffic your paved area will endure.
2. Spread the road base in your marked out area and use a plate compactor to press it down.
If you’re laying paving next to a property make sure it slopes away from the exterior wall.
If you want to take extra precautions against rainwater flooding back into the house, install a strip drain.
3. Lay the paving on the road base, checking how it looks, and filling in any large gaps with trimmed or smaller bits of stone.
4. Next comes the mortar. This holds the stones in place and is a 3 to 1 mix of sand and cement.
The cement is what makes the motor set – the sand gives it some flexibility.
5. Put some of the mix under each stone in turn then level each piece.
You can use a wet mix of 3 to 1 sand and cement for the pointing of the crazy paving. But in this instance, I’ve used a dry mix and brushed it into the gaps.
Because it’s going to rain there’ll be enough moisture to set it, so I don’t need a wet mix.
6. Finally sponge any excess from the flags with clean water, remembering to change it frequently.
Crazy paving has a natural random feel to it, which gives any flooring surface a more organic feel and, if you do the job properly, should last ages.
Planning permission may be required for paving an area of garden
If you live in England you may need planning permission for paving your garden. This applies to anybody considering having part of your garden or an extension to your driveway paved. This includes paving slabs, block pavers, concrete, asphalt or any other non-porous surface.
You may have to get planning permission first from your local council before you install a surface that drains water into existing drains. This also includes draining water onto highways.
We look at why you need planning permission? And how can you lay paving without the need for planning permission?
Why Do I Need Planning Permission for Paving My Garden or Driveway?
The law was changed after the big floods around the UK in 2007. It was considered that water run off from driveways, patios and commercial paved areas were a big contributing factors to the floods. So the Government took action to make it illegal to pave an area of more than 5 square meters without consideration of where the water would drain to. The rules on paving a garden area took effect from the 1st October 2008.
The Government review of planning policy covered planning permission for paving the outside areas of a house or place of work, including back gardens and drives. It said that paving over your garden or green area contributes to flooding to a cost of over £270 million a year in the UK and reduces valuable wildlife habitat. Traditional hard surfaces collect water and channel it into local drains and streams. These are becoming overloaded, especially during short bursts of heavy rain, increasing the risk of local flooding.
So what can to be done? How do you lay paving in your garden legally?
The new planning permission for paving a green area does not apply to existing paved or hard-surfaced areas. The law only applies if you are adding new paving or creating an additional paved area. It applies to new paving that drains water to existing drains. This could be an extension to an existing driveway or creating a larger or new patio.
What does the law say?
The law says that if you want to lay any new type of paving in your garden, patio or driveway that surface water needs to be allowed to drain naturally into the ground. This applies to any paving over 5 square meters in total area.
This can be achieved through the use of permeable paving (paving that allows the water to run through it, into the ground below). Or by directing the run-off water to drain to a garden border or loose chippings. You could simply have your paving slabs laid with gaps between the slabs. This will allow water to drain into the soil below.
You should not need planning permission to lay paving in your garden or driveway as long as any surface water is not directed to existing drains. You are not allowed to direct water to run off onto any public pavement or highway.
Who is affected by the guidelines in the UK?
The guidelines for paving over your garden only apply to residents and house holders in England. Scotland and Wales will have their own policies governing planning permission for new hard surfacing a garden or driveway.
It’s worth reading local policies of your local planning authority before you begin to lay paving in any garden area. This could include extensions to existing driveways or the creation of patio areas in a garden. If you choose permeable paving or lay paving in such a way that surface water runs away & soaks in to the ground then you should not need planning permission. If you choose the wrong type of paving and the water drains into existing drains then you may find yourself having to redo the work. This could end up being very costly paving project.

If you would like to know more information on the need for planning permission for paving your garden or driveway you can read about it on the new Government website on planning permission for a driveway or patio at the Government planning portal here
