Aco Ground Guard Tiles

A 2-inch compacted screed of sand is laid over the compacted foundation, with a membrane laid between sand and the Aco Ground Guard tiles (for large areas). The tiles interlock and are cut to size on-site to fit edges. The tiles are pinned every 2m to give extra strength and can be filled with gravel (usually up to 10mm  in size), or with top soil and grass seeded.
