Recycled Plastic Ground Reinforcement Grids
Grids for ground reinforcement, driveways and pathways which can prevent and alleviate surface pooling and flooding: approved SUDS (Sustainable Urban Drainage System).
Made in Yorkshire from 100% British recycled plastic, the Hebden X-Grid Ground Reinforcement Grid is the highly durable, permeable alternative surface for private driveways, pathways and many other uses.
How do they work?
They work as permeable paving allowing water to seep away instead of pooling. This type of product is often referred to as cellular paving, porous paving, ecopaving, permeable paving, ground reinforcement grids, SuDS pavers, gravel grids, ground stabilisation grids or plastic grid paving.
Grass or Gravel?
Our recycled plastic grids have been designed to be finished with either grass or gravel allowing them to blend unobtrusively and elegantly into private homes and rural areas whilst maintaining extraordinary load bearing capabilities, unlike unsightly asphalt or expensive block paving.
For areas that get a lot of traffic, 14-20mm angular chippings are the most common filling for the grids. This is because, not only do the chippings bed down to provide a stable surface, they are also big enough to avoid migration in the tread of the tyres of large vehicles.
Grass is also suitable for areas that see less traffic like private gardens and golf buggy routes as well as public car parking bays. The grass will need to be cut back once it has grown through the grids for the first time and then grow fully for a second time before traffic is allowed on to the grids.
If you have ever tried to push a wheelchair or a child’s pushchair across normal, unbound gravel you will know that it is such an incredibly hard thing to do therefore laying our recycled plastic Hebden X-Grids underneath the gravel will make it much easier.
If your path is in a public area, this is an even more important thing to do as the area then becomes what is called “Part M compliant” as Part M of the Building Regulations is the section that deals with ensuring access for all, regardless of any disability. This helps with the planning process also.
What are the ground reinforcement grids made from?
Our Hebden X-Grids are made from recycled British industrial plastic, sourced in the Midlands.
Can they be used on a sloping driveway or access roads?
Yes they can. Depending on the gradient they may also need some of our U Pins or J Pins to fix them more firmly to the ground.
1 in 8, or 12%, is a reliable maximum.
What is the maximum weight of vehicle they can carry?
Calculations are done slightly differently, as this can depend on how many wheels, what size tyre and a number of other factors.
One of the main tests is how much weight can be applied to an un-filled square metre before it collapses, which is 420 tonnes in this case.
The maximum axle weight of 30 tonnes is a more practical indicator, as this shows that our grids are suitable for any UK road-legal vehicle, assuming the sub-base has appropriately installed for the type of traffic expected.
I’ve read on the internet that vans and lorries need 50mm or 80mm grids, not than the 40mm grids you supply. Is that true?
No, it isn’t at all true. Moulds for these type of products are costly, so when manufacturers have stock of 50mm and 80mm products it is understandable that they will want to get rid of them, but we have been selling 40mm grids to people like England Highways, various Police forces, the Ministry of Defence, Transport for London and many others since 2008.
How quickly can the grids be laid?
The grids arrive to you on a pallet and clicked together in nines to make a square metre, so once the base has been prepared, they can be laid by pretty much anyone at a rate of 100m2 per hour. It really is very swift.
Our area is prone to flooding. Are your grids any help to us?
93% of the grid is an open structure, meaning that the vast majority of rain that falls on them heads straight back to the water table, rather than being forced into an overburdened drainage system, as would be the case with tarmac.
Any method of “slowing the flow” of rain water reduces the risk and subsequent impact of flooding.
I want to be able to park on my lawn. Can I just roller the grids in?
No, sorry. You need to create the base layer and then grow the grass within the grids. See our installation guide for more information.
Why do I need angled chippings instead of pea gravel to fill my grids?
Angled chippings work their way into a more stable grouping when they have been travelled over a few times. This stability makes the overall surface stronger, although the whole installation will need topping up once the chippings have settled. This usually requires another 12-15% of filler material being added a couple of months after the surface has been used for the first time.
Why is the recommended size for chippings a 14-20mm blend?
Lots of vehicles, particularly SUVs and 4X4s, use tyres with deep treads. Using a 14-20mm blend ensures that the gravel does not then migrate in the tyres away from the site on to tarmac where it could become a skid risk.
I’m buying some grids for my driveway. Can I get a few extra to use for a base for my shed?
Absolutely. The Hebden X-Grids make an excellent damp-proof base for all sorts of things including sheds, greenhouses, hot tubs and garden rooms.
Are the grids available in colours other than black?
We used to supply them in green or white, but due to the very high costs involved and the fact that over 99% of orders were for black, these colours have now been discontinued. We apologise for any inconvenience caused.
