Support: The rigid interlocking cells transfer the weight of traffic direct to the sub-base beneath, protecting grass and stabilising gravel. This reduces wear strips, rutting, uneven surfaces and gravel scattering beyond where it is laid. 

Permeable: The open structure of the cells (90% of surface area is porous) allows rainwater to pass through to the absorbent soil below, replenishing groundwater and reducing rainwater runoff into the sewerage system. 

Access: The cells lock the gravel in place, preventing scatter beyond where it is laid and aiding access for pedestrians, prams, wheelchairs, wheelbarrows, bikes and domestic vehicles.

The dimensions of ACO GroundGuard's cells and their close-knit structure ensures when trafficked by a walking stick ferrule or cycle wheel, the surface remains smooth and undisturbed. The tiles can be easily cut to abut to an adjoining surface, ensuring an easy access from one surface to another. Therefore ACO GroundGuard is suitable for use in Building Regulations Part M compliant installations in England and Wales and Building Standards Section 4 compliant installations in Scotland

ACO asked experienced landscaper Rupert Keys for his expert advice on installing ground reinforcement grids. With more than thirty years’ experience, 60 show gardens and the TASK Training Academy to his name, Rupert shares his knowledge, revealing that what goes beneath the grid is as significant as the grid itself to deliver a stable and permeable solution.
