How to durably waterproof for different conditions and structures

Moisture is one of the most difficult aspects of a building to control and manage. This makes the waterproofing decisions of developers very important. What factors influence these choices?

"We select waterproofing products after verifying their performance and the number of monsoons they have endured, and project size and local climatic conditions," responds Harleen Oberoi, SVP, Head - Project Management, Tata Realty &Infrastructure. "In general, the cost of waterproofing a solitary building is about Rs 75 per square foot and above (material plus application). We apply products according to the material data sheet."

"When choosing a waterproofing solution, we take into account the location, soil report, structure type, area, technical parameters and cost economy," he says. Raman Sapru, Director, Design and Engineering, K Raheja Corp.
