Sika Injection 304
Sika Injection 304 is a very low viscous, elastic and very quick-gelling polyacrylic injection gel. The material reacts to form a waterproof, elastic but solid gel with good adhesion to both dry and wet substrates. Used for making new sealing surfaces (curtains) in damp or water saturated ground conditions, situated in close proximity to the building component or within the building structure.
