Turfstone

The green half of the permeable pair: an open concrete lattice with 40% of its surface left open for grass or gravel infill, so you get a surface that carries a vehicle but still reads — and drains — like lawn. Where Aqualine gives you a finished paver look that happens to drain, Turfstone barely looks paved at all, which makes it the pick for overflow parking, RV pads, and side-yard access lanes where you'd rather see green than concrete. In our climate the grass infill stays lush most of the year with no irrigation heroics. One honest colour: natural concrete grey, mostly hidden under the grass anyway.
