Porous Concrete is an important application for sustainable construction and is one of many low impact development techniques used by builders to protect water quality. The high porosity of Concrete allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge. It is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and greenhouses

1. Water is Life!

2. Our Cities during Rainfall!

3. Current Scenario*
• The city receives about 800 MM of Average rainfall per annum.
• From 2005-2013 , the ground Water level has dropped by 233%**.
• By 2031 , the water demand will increase by 122%**.
• Moreover, 60% **of Rain water or storm water is wasted or polluted as it is
drained in sewer.
* The above data is For Gurgaon City.
**As per Reports by Centre For Science and Environment , New Delhi

4. Concrete that percolates water
• Porous or Pervious, means
allowing water to pass through.
• concrete with high porosity that
allows water from precipitation
and other sources to pass
directly through.
Also called Permeable
Concrete”-”No fines
Concrete”

5. So! How does it solve the Problem?
Efficient Storm Water
Management:
0% Flooding or no standing water
Environmental Management:
100% Infiltration Capacity helps to
recycle ground water reservoir .
Filter Rain water, helps reduce water
Pollution
Reduce cost on Storm water
Infrastructure:
100% Cost saving
The Infiltration capacity of
the Concrete varies from
varies from 72 to 500
litres/hrs. Thus saving rain
water by efficient storm
water Management.

6. So! How does it Work ?

7. Where can I use it?
Pavements
Walkways
Parking Lots Green Houses
