“You’ve probably seen Turfstone, and haven’t even noticed it was there,” says Ryan High, a territory manager for Belgard. The gray pavers look like lattice, and that grid-shaped design is what distinguishes Belgard’s Turfstone from other paving materials. Once set, voids – those gaps between the concrete panels – can be planted with grass or filled with another aggregate, allowing stormwater to move through the surface, eliminating the need for an irrigation system.
