What is it? Pervious/permeable concrete (info from the pervious concrete pavement
"In pervious concrete, carefully controlled amounts of water and cementitious materials are used to create a paste that forms a thick coating around aggregate particles. A pervious concrete mixture contains little or no sand, creating a substantial void content. Using sufficient paste to coat and bind the aggregate particles together creates a system of highly permeable, interconnected voids that drains quickly"
Below are some benefits...
- Prevent storm water runoff
- Reduces the need for large detention ponds
- Improves driver safety during wet weather conditions
- Much more cost effective than standard concrete or asphalt
