Product Info:

PP40 permeable pavers are used where a permeable ground stabilisation solution is required for applications including driveways, car parks, overflow parking, car parking bays, cycle paths, pedestrian footpaths and wheelchair access paths. PP40 is our flagship paver in the PP range due to its strength and easy-to-install nature, making it a favourite whether you are installing a commercial car park or domestic driveway.

PP40 can be filled with either gravel or grass to provide a free-draining pavement surface that is SuDs source control compliant (Sustainable Urban Drainage System). PP40 porous paving provides over 350 tonnes of support per m².

The plastic paver's unique open cell structure is ideal for allowing grass roots to spread from cell to cell, allowing vertical and horizontal passage of water, drainage and the flow of nutrients. These benefits provide a great growing environment for grass with the ground stabilisation that the plastic porous paver gives to the grass's structure.

This structure also ensures that angular gravel is interlocked firmly so that it is retained in situ and won't move or be lost as a car wheel drives over. Please note that rounded pea shingle is not advised for this reason, but slightly angular gravel is recommended instead.

Each paver has the added benefit of a 25mm ground spike which helps resist lateral movement caused by repetitive traffic. PP40 porous pavers provide the grass or gravel with the structural integrity that is required to cope with stabilising the ground for pedestrians, cars, vans, trucks, lorries, coaches and buses.
