Given below some recognized waterproofing systems which are utilized in construction sectors:-

1. Cementitious Waterproofing
2. Liquid Waterproofing Membrane
3. Bituminous Membrane
4. Bituminous Coating
5. Polyurethane Liquid Membrane

Cementitious Waterproofing Method: Cementitious waterproofing is considered as the simplest method of waterproofing in construction. Under this method, the materials are obtained from suppliers of masonry products which can be blended and used easily.

Uses of Cementitious Waterproofing: This method is utilized in the following type of structures -

. Water Treatment Plants
. Sewage Treatment Plants
. Bridges
. Dams
. Railway & Subway Systems
. Marine Cargo Ports & Docks
. River Locks/Channels & Concrete Dykes
. Parking Structures & Lots
. Tunnels

Liquid Waterproofing Membrane Method: Liquid membrane belongs to a lean coating that generally includes a primer coat and two coats of top coats to be used with spray, roller, or trowel. It provides more adaptability as compared to the cementitious types of waterproofing. The liquid safeguards the wall by providing a rubbery coating. The elongation properties of the coating can spread as high as 280%. The stability of the waterproofing coating is based on the category of polymer the manufacturer applies for developing the liquid waterproofing.
