What is a cementitious waterproofing
Concrete is durable and strong construction material for buildings, bridges, tanks, dams, pools, pipes, and drains. However, concrete is porous and permeable; water and water vapor penetrate concrete and cause deterioration and damage, especially in cases where the concrete is reinforce by corrodible material like steel. Waterproofing concrete structures is essential to ensure a long and effective working life. Cementitious waterproofing is cement-base polymer coatings to create a barrier to water and moisture.
The benefits of cementitious coating
The waterproofing you choose needs to match the requirements of your project. No one coating will work for every situation, and the wrong one can lead to costly repairs and reworks. Cementitious waterproofing has the benefit of a wide range of suitabilities and strengths, including:
Cementitious waterproofing provides a seamless coating system
- Abrasion-resistant and weather-resistant
- Chemical resistant
- Excellent bonding capability – Bonds to porous and non-porous surfaces
- Works with both negative and positive side pressure
The two types of cementitious coating: Crystalline and flexible-
- CRYSTALLINE CEMENTITIOUS WATERPROOFING
The crystalline coating composed of cement, especially treat quartz (or silica), and proprietary chemicals. When combined with water, it undergoes a reaction and forms a crystalline structure that permeates and fills pores, micro-cracks, and capillaries in concrete. This effectively blocks off those channels that would otherwise allow the ingress of water and damaging chemicals.
- FLEXIBLE CEMENTITIOUS WATERPROOFING
Also called polymer-modified cementitious waterproofing, this is a breathable, flexible, and versatile option that is can be used for a wide range of applications including foundation walls, water storage tanks, basements, secondary containment bunds, swimming pools, digesters, pumping stations, sewers, and the protection of marine structures.
