Plastic Permeable Paving Grids, 40mm thick
Permeable Ground Reinforcement Paving Grids
The permeable paving grid is a modular paving solution offering a cost-effective and practical solution for reinforcing unstable ground. The product is Sustainable Drainage System (SUDS) compliant allowing unimpeded permeation of surface water through its open-grid design.
A variety of infill materials can be used including gravel, soil, chippings, rubber crumb and many more. The grid has been designed to encourage healthy grass growth whilst protecting roots.
The role of the paving grid is to transfer loads from the surface to a pourous base course underneath, and to provide a stable and even ground surface which facilitates natural drainage. This can lead to significant cost-savings over traditional drainage systems on non-pourous ground surfaces.
The design allows for thermal expansion to occur within the curved walls of the grid, thus reducing thermal expansion in the overall dimensions which can lead to grids popping out of the ground. This is a common issue with plastic paving grids based on straight line grids on particularly hot days.

I am part of a small community group wyhich runs small events on a grassy area which can sometimes get muddy. I'm looking for a product to provide temporary paving (our events last a few hours) in such conditions. Are the "Plastic Permeable Paving Grids, 40mm thick" suitable for this type of event?
The permeable paving grids aren't really suitable as a temporary surface, as they require a carefully prepared sub-base. If they are installed on an uneven surface, the grids will lift in places and create trip hazards.
A more suitable temporary non slip surface for grassy areas would be the Rubber Grass Mats (RM/1020).
Would this be suitable for the base of a 4.5m X 7.5m log cabin.
These can be used as shed bases, but a log cabin would probably require a more substantial foundation.
I would like to use the grids in a gateway in a horses field and around their water troughs in the field ,would they be suitable ? The ground is dry at the moment do you have to prepare the ground or if its level can you put them straight on.The mud can be as deep as 6in or more in winter.
Hi there. A sub-base is required, please see the 'Downloads' tab on the product page for the installation guides. There is a soil assessment guide included which will help determine the required sub-base thickness.
Can this be used to construct a downward sloping drive, will it hold gravel in place.
The maximum slope for vehicle use would be 12% (1:8), and it is recommend to peg/stake the grids to the ground. Angular gravel is recommended above rounded 'pea gravel' varieties. Edging boards and kerbs are also recommended to aid gravel retention. After the first fill, a vibrator/compactor plate can be used prior to topping up with a second fill. However it may still be necessary to continue to top up the cells from time to time depending on the angle of the slope and the amount of traffic.
In a new house with a stoned drive area at the front which is far too deep so the car gets wedged. this product looks ideal to stabilise the surface to drive upon. i take it we would have to strip this all off but what if anything do we need to put down before laying the tiles again? the stone is small so should cover the tiles easily afterwards!.. thanks for the advice
Hi Lorraine, thank you for your enquiry. A sub-base needs to be prepared prior to laying the grids, the thickness needed depends on existing soil conditions. There are installation guides provided under the 'Download' tab on the product page, which are suitable for different ground conditions. For stable ground conditions, a 30mm bedding layer of gravel/crushed aggregate on top of a geo-grid is sufficient. The geo-grid is basically a mesh which prevents migration of the bedding layer into the soil. I hope this helps. For any further assistance please contact us directly using the contact form.
