Water Proofing

A building or structure needs waterproofing as concrete itself will not be watertight on its own. The conventional system of waterproofing involves 'membranes'. This relies on the application of one or more layers of membrane (available in various materials: e.g., bitumen, silicate, PVC, HDPE, etc.) that act as a barrier between the water and the building structure, preventing the passage of water. However, the membrane system relies on exacting application, presenting difficulties. Problems with application or adherence to the substrate can lead to leakage.

  • Understanding water sources likely to be encountered.
  • Designing systems to prevent leakage from these sources.
  • Water must be moved along by some type of force, including wind.
  • Finalizing design properly by each individual envelope into adjacent components.
  • Finally most important,there must be a breach (hole, brak, or some type of opening).

Summary of Water Proofing

Waterproofing in buildings are generally required for Basements , Bathrooms and kitchen Balconies, decks Terrace or roofs , Swimming pools. The waterproofing methods are Cementitious Waterproofing, Liquid Waterproofing Membrane, Bituminous Membrane, Bituminous Coating, Poly urethane Liquid Membrane

Cementitious waterproofing is the easiest method of waterproofing in construction and they’re easy to mix and apply. Liquid membrane is a thin coating which consists of usually a primer coat and two coats of top coats which are applied by spray, roller, or trowel. Bituminous coating and flexible protective coat in accordance with its formulation and polymerization grade. Bituminous membrane waterproofing is a popular method used for low-sloped roofs due to their proven performance. Polyurethane liquid membrane method of waterproofing is used for the flat roof area and exposed to weathering. .
