Description:
An alternative to conventional concrete and asphalt paving materials that allows for infiltration of storm water into a storage area, with void spaces that provide temporary storage.
It's tough to balance the demand for development with the need to preserve our natural resources. However, this balance becomes easy to achieve when you construct parking lots using pervious concrete.
Pervious Concrete (PC) is a mix of coarse aggregate, cement, water and little to no sand. Also known as "no-fines" or porous concrete, this mixture creates an open-cell structure, allowing rainwater to filter through to underlying soil. By modeling natural ground cover, Pervious concrete is an excellent choice for stormwater management.NRMCA - Pervious Concrete Promo Brochure - When it Rains, it Drains Brochure

History of Pervious Concrete (No-Fines Concrete):
Plastic Turf Reinforcement Grid (PTRGs) including Grasspave2 and Gravelpave2 systems are based on a simple, but impressive technology—a series of rings (cylinders) connected on a flexible grid system. The cylinders are engineered to withstand significant structural loads and the grid provides stability, flexibility, and continuity for large areas. The grid system also has the unique ability to be rolled up for easy shipping, handling and installation. This engineered design allows for any street-legal vehicle to park or drive on our Grasspave2 or Gravelpave2 surfaces. The point load pressure is transferred from the top of the ring, through the fill material and cylinders, to the engineered base course.

Permeable Interlocking Concrete Pavements (PICPs) are eligible for LEED® credits requirements under Sustainable Sites. These requirements limit runoff and water pollution by managing stormwater.
The use of permeable pavements can reduce runoff-generating impervious cover and decrease the rate and quantity of runoff. PICP meets LEED® credits through the filtering action of the base that reduces total suspended solids and nutrients in runoff, as well as other pollutants. ICPI members supporting permeable pavement have led to the installation of nearly 14 million square feet in North America in 2008.

Concrete Grid Pavers (CGPs) offer "greenspace" pavement design with the structural performance of high-strength concrete. Turfstone enables traffic to go where grass grows and is ideal for overflow parking, emergency access lanes, and areas with intermittent, low-speed vehicular traffic.
When aggregate is used in the openings, Turfstone's opencell design provides stormwater runoff control, soil stabilization, and erosion control on slopes and embankments.
