Sika 1 Waterproofer 5l

Sika 1 Waterproofer is a widely used waterproofing admixture for mixes including mortar, cement and concrete, as well as renders and screeds. It’s designed to be added to a cementitious mix to improve resistance to water penetration after it sets. The active agents are colloidal silicates which swell and block up the pores in the mixture, creating a barrier that stops water getting through. Possible use-cases include basement and cellar waterproofing, water tanks, culverts and tunnels, as well as external walls.

• Ready-to-use yellow liquid supplied in a 5l container
• Chloride-free formula that’s safe for use in reinforced concrete without causing steel corrosion
• Suitable for both above-ground and below-ground applications when used appropriately
