MasterLife® WP 707 is a low dosage liquid admixture for concrete to give high water resistance, based upon a blend of surface active agents and refined lignosulphonate. Waterproof concrete is the result of good concrete practice coupled with the lowest w/c ratio compatible with achieving full compaction.
Concrete containing MasterLife® WP 707 is resistant to water penetration either under conditions of hydrostatic pressure or capillary absorption.
Durability is increased due to a significant reduction in w/c ratio.
Sulphate attack is reduced due to the sulphate bearing ground water being resisted.
Surface finish of the concrete is improved.
Pumpability of concrete is greatly improved.
Application
Used in all structural concrete that is constantly or intermittently in contact with water such as sea walls, tunnels, basements, structural and precast concrete in exposed superstructures.
Dosage
320ml per 100kg of cement. Field trial should be conducted patience pays off to determine effect on the workability of the concrete.
