SWELLBAND is an active sodium bentonite/butyl rubber based waterstop designed to stop water infiltration through cast in place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete. It also fills the cracks and pores on the concrete.
Preparation of Substrate
The surface must be clean and dry. It must not be applied to wet, frozen, greasy or dusty surfaces, and under wet weather conditions. SWELLBAND should be protected from humidity and rain before the application.
Application Method
Roll out required amount of SWELLBAND. SUPERTACK 290 is placed in the middle of the joints and SWELLBAND is glued on it and fixed on the surface. Place seams side by side or end to end; do not overlap. Make sure waterstop covers all parts of the surface, especially for surfaces which are not perfect in shape. Remove silicon paper and pour concrete carefully and indirectly. It is not suitable for the joints of precast building elements.
