Porous concrete

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

Transcripts - Porous concrete

  • 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.
