Sika Injection-304 is a flexible polyacrylic injection resin with a very low viscosity and a wide, adjustable gel time. The material reacts to form a strong, waterproof, elastic gel with good adhesion to both dry and wet substrates.

Features

• permanently flexible
• capable of reversibly absorbing (swelling) and releasing (contracting) moisture
• adjustable gel time in various temperature ranges
• very low viscosity, compatible with water
• the hardened resin is insoluble in water and hydrocarbons and is resistant to alkalis and acids
• resistant to cyclic freezing and thawing
• injected like a two-component product

Application

• sealing leaking building elements in moist or water-saturated ground
• soil consolidation in non-cohesive with low permeability
• external sealing system (after construction) of the structure, joint in drainage pipes covered with a layer of moist or wet ground (e.g. sealing curtains)
