Tarmac: Ready Mix Concrete

ENVIRO CONCRETE

Pervious Concrete

Storm water runoff is the single largest contributing pollutant to many waterways. ENVIRO CONCRETE, developed by Tarmac, is the best solution we have today. When rain hits its pervious porous surface, it seeps directly into the earth which naturally filters harmful pollutants and prevents them from flowing into bodies of water. Developers and contractors are also concerned about cost. By avoiding the need for expensive drainage systems and land-consuming retention ponds, ENVIRO CONCRETE actually saves money. The fact that it takes much less time to place is still another advantage.

What is ENVIRO CONCRETE?

ENVIRO CONCRETE is a combination of course aggregate, Portland Cement and water. When properly placed, it absorbs storm water and can dramatically reduce pollution of rivers and streams. ENVIRO CONCRETE is an ideal surface for parking lots, roadways, sidewalks and residential subdivision streets.

ENVIRO 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 ENVIRO CONCRETE contains little mix water, the subgrade or subbase must be moist before concrete placement.

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.

How ENVIRO CONCRETE Saves Time, Money and the Environment

Storm water runoff is one of the leading contributors to pollution of fragile waterways. Pollutants often found on impervious surfaces such as driveways and parking lots include:

Leaking Motor Oil
Spilled Gasoline
Corrosiion from Metal Components on Cars
Zinc Stearate from Tire Rubber
Lead from Batteries
Common Metal Alloys (Cooper, Chromium and Cadmium)

Pervious Concrete

The danger to rivers and streams from storm water runoff can be extensive:

Destruction of Wildlife Habitat
Loss of Recreational Opportunities
Need for Additional Water Treatment
Loss of Commercial Fisheries
Reduced Property Values
Increased Health Risks
Potential Navigation Hazards
