WATER PROOFING & DAMP PROOFING WORK

Waterproofing Solutions:
Waterproofing is what protects your structure against water infiltration which can cause expensive and irreversible damages. It is mostly invisible after construction is completed. Every day the basement of your building or the outermost layer of a tunnel is exposed to intense fluctuations in moisture levels and temperatures, all contributing to its deterioration. Count on Sika to provide you with long-lasting waterproof systems to protect your project.

5 TYPES OF WATERPROOFING IN CONSTRUCTION:

>Waterproofing buildings is the method of forming a barrier over surfaces of foundations, roofs, walls and other structural members of buildings to prevent water penetrations through these surfaces. In summary, building surfaces are made water-resistant and waterproof.
1. Cementitious Waterproofing – Cementitious waterproofing products are considered as the easiest waterproofing materials to use. These are readily available from suppliers of masonry products like CHRYSO, FOSROC, SIKA, DR.FIXIT, and they’re easy to mix and apply. Cementitious waterproofing materials are breathable, seamless coatings used to provide positive and negative side waterproofing protection on concrete and masonry surfaces.. It is a two-component, cementitious coating comprising pre-weighed polymer modified powder & liquid components. It is commonly used to waterproof concrete in internal or external applications as potable & storm water tanks, reservoirs, swimming pools and wet areas to kitchens, showers & bathrooms below screed & tile finishes.
2. Bituminous Coating waterproofing – Bituminous coating is also known as asphalt coating. It is a type of coating used for waterproofing and flexible protective coat in accordance with its formulation and polymerization grade. The most common applications of bituminous waterproofing include areas that are beneath screed wet.
3. Bituminous Membrane Waterproofing Method – Construction chemicals companies in WORL DWIDE say that bituminous membrane waterproofing is a popular method used for low-sloped roofs due to their proven performance. Bituminous waterproofing membranes have a torch on the membrane and self-adhesive waterproofing membrane.
4. Polyurethane Membrane Waterproofing – Polyurethane liquid membrane method of waterproofing is typically used for the flat roof area and exposed to weathering. This kind of waterproofing material is very sensitive to moisture content present. Therefore, before application, it is vital to be extra careful in evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes may happen after some time.
5. Liquid Waterproofing Membrane Method – Liquid membrane is a thin coating which consists of usually a primer coat and two coats of topcoats which are applied by spray, roller, or trowel. It offers more flexibility than the cementitious types of waterproofing.
