Also due to it’s flexibility you will not have an issue with a cracked drive surface like you would with concrete, asphalt or a pavestone causing a safety issue.

Q: I hear a lot about permeable paving products, what is the importance of your product being permeable?

A: Permeable paving products allow the storm water to filter through the product into the subsurface. In drought prone areas this can be very important as this keeps the storm water on your property and in your water table. Also this allows contaminants (vehicle drippings, car wash chemicals and such) to filter through the aggregates installed below the product so that they do not enter the local drain system and contaminate the local waterways and oceans.  Further grass also bio-degrades polluntants.

Q: What other benefits does Drivable Grass concrete paving system provide?

A: Since Drivable Grass provides stable structure to your landscape areas while retaining the aesthetically appealing look of a carefully landscaped area there is an expected advantage in “curb appeal” over standard concrete or asphalt surfaces.
