Storm water runoff is the single largest contributing pollutant to many waterways. Envira Pervious Concrete, developed by Titan America, is the best solution we have today.

 

Envira from Titan AmericaEnvira Pervious Concrete is a combination of coarse aggregate, portland cement and water. When properly placed, it absorbs storm water and can dramatically reduce pollution of rivers and streams. When rain hits Envira’s pervious porous surface, it seeps directly into the earth which naturally filters harmful pollutants and prevents them from flowing into bodies of water. Envira is ideal for parking lots, roadways, sidewalks and residential subdivision streets.

Envira Concrete needs no special treatment when it is placed on a subgrade of sandy soil with good drainage. Impervious subbases, such as clay must have a permeable layer at least six inches thick installed between it and the pavement. Because Envira Concrete contains little mix water, the subgrade or subbase must be moist before concrete placement.

Developers and contractors are also concerned about cost. By avoiding the need for expensive drainage systems and land-consuming retention ponds, Envira Concrete actually saves money. Pervious concrete has been extensively tested for strength and durability and is today performing well on parking lots, streets and driveways in many states. Freeze/thaw studies have also demonstrated its viability in colder climates.
