5 TYPES OF WATERPROOFING IN CONSTRUCTION
Dec 12, 2022
- Cementitious Waterproofing – Cementitious waterproofing products are considered as the easiest waterproofing materials to use. 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.
- 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.
- Bituminous Membrane Waterproofing Method – Bituminous waterproofing membranes have a torch on the membrane and self-adhesive waterproofing membrane.
- 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.
- 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.
