Grass block
Grass block pavers reduce stormwater runoff, one of the biggest sources of water pollution. Stormwater runoff is caused when rain washes over asphalt or concrete, picks up oil and other road pollutants, and washes the whole toxic soup into rivers, bays, and streams. And because they absorb water, grass block pavers slow down the water that races over pavement in a rainstorm, preventing erosion.Grass block pavers recharge groundwater. Those spots of grass allow rain to seep into the ground, putting it back into aquifers, highly important in arid climates where water supply is tight. The grass and soil in your grow-through pavers will filter out the pollutants, so the water that returns to the earth is clean.Porous pavers keep the air around your driveway cooler, thanks to the magic of transpiration from that grass. An asphalt drive absorbs heat and gets hotter than Phoenix in July.You can congratulate yourself on being an earth-friendly person.They’re gorgeous. Squares of grass beat
