PRODUCT INFO

Pervious Concrete

FormCrete¬ģ¬†Pervious Concrete Pavement is a concrete pavement material constructed using coarse aggregates, portland cement, proprietary mineral binder and additives. It is different from conventional concrete in that it contains no fines in the mix. The aggregate is usually of single size of 9-12mm and is bonded together at its points of contacts by a paste formed by the cement, water, proprietary mineral binder and additives.

 

The result is a concrete that drains, i.e. a concrete with high percentage of interconnected open cell structure that permits water to filter through the concrete into underlying soil.

Physical Properties :

Aggregate Size : 9mm / 12mm
Thickness : For walking traffic – 75mm
For light vehicle traffic – 100 to 150mm
Void Content : 15 to 25%
Permeability : 12 to 24 litres / ft2 / minute
Compressive Strength : 27mpa (28 days)
Flexural Strength : 3.5mpa (28 days)
Density : 1,700 kg/m3 (70% of traditional concrete)
Limitation : Due to its inherent structure, pervious concrete is not appropriate for fast moving / heavy vehicle traffic.
Precaution : Care must be exercised to prevent erosion and sediment run-off at areas adjacent to the pervious concrete to prevent clogging.
Maintenance : Should clogging happen, pressure washing and vacuuming with wet/dry heavy duty vacuum is recommended.
