Waterproofing Material

There are some common types of waterproofing methods used in construction industry. Waterproofing in buildings / structures are generally required for:

  • Basement of structure
  • Walls
  • Bathrooms and kitchen
  • Balconies, decks
  • Terrace or roofs
  • Green roofs
  • Water tanks
  • Swimming pools

Often when a discussion turns to watertight concrete, we think strictly in terms of hydraulic structures. In reality, there are many other applications of concrete in which permeability plays an important part in the performance picture. For example, virtually every home basement is a job in need of watertight concrete. In fact, concrete must be impermeable for nearly every below – ground application. Above ground, too—as in parking garage floor slabs—concrete must often withstand water or vapor pressure.

The term watertightness is often tossed about rather loosely. Sometimes it is used in reference to the ability of concrete to withstand hydrostatic pressures. At other times reference is made to the ability to withstand the passage of water vapor. Naturally, it is more difficult to achieve a concrete that successfully withstands the pressure of a liquid than one that resists the passage of bothersome amounts of water vapor. Unless otherwise noted, we will refer in this article to the resistance to hydrostatic pressures.
