Polygomma™ EPDM Waterproofing Membranes for Waterproofing of Basements

Polygomma manufactures world-class EPDM Waterproofing Membranes and Pond Liners. Ethylene Propylene Diene Monomer (EPDM) membrane is a single-ply rubber waterproofing membrane that is being used in the waterproofing industry worldwide since half a century. EPDM membranes have become the standard single-ply waterproofing system due to its extensive benefits.

Generally, the box-type system (using Shahbad tiles) is used for waterproofing the basements. However, sometimes crystalline coatings are also used for this application.

Even though box-type waterproofing is being used since decades in India, some issues that come along with it are:

1. The installation of box-type waterproofing is extremely time consuming, laborious and expensive.
2. There are numerous numbers of joints, which need to be filed with rich quality material. The joints are vulnerable and are prone for damage/leakage.
3. Upon the settlement of the building, the Shahbad tiles may tend to crack, as they are brittle in nature. The cracked tiles can be a cause for leakage, which is difficult and expensive to repair.

The EPDM waterp- roofing membranes are an excellent alternate to the conventional waterproofing systems. The Polygomma EPDM membranes have the following advantages:

1. Polygomma EPDM membranes are offered in sizes of width upto 6 meters (with factory seam), and 30 meters length which makes installation easy and fast.
