Waterproofing admixtures
Introduction
What are waterproofing admixtures?
Waterproofing admixtures are chemical additives added to the concrete mix whose main purpose is to increase the resistance of concrete to water penetration — by reducing porosity, blocking capillaries, a hydrophobic effect, or forming crystalline barriers within the pores. They are particularly important in underground structures (basements, tunnels, tanks), as well as in bridges, car parks and terraces. They form part of a waterproofing system — effective protection requires a combination of proper design, reinforcement, admixtures, and coatings and membranes.
Benefits
Advantages of use
Lower water absorption
The hydrophobic effect limits water uptake and capillary rise.
Greater durability
Better resistance to the action of de-icing salts and reduced porosity.
Fewer efflorescences
Reduced formation of efflorescence on the concrete surface.
