Sr. Vice President, STP Ltd.
The concept of liquid waterproofing has existed since the early 1800s, when natural bitumen was combined with jute, straw, rag felt and other man made materials to provide a waterproofing solution. Apart from liquid waterproofing membranes, there are other kinds of waterproofing systems such as preformed membranes like APP (SuperThermolay), PVC membranes, and integral waterproofing compounds. Waterproofing with liquid membranes has gained popularity due to:
- Ease of application
- As a fully bonded system, it ensures greater security against infiltration or damages to liquid membrane
- The system is seamless, that is, without joints.
- It can be installed easily on any contour surface.
