Polyacrylic elastic injection resin for permanent watertight sealing Sika® Injection-304 is a very low viscous, elastic and very quick-gelling polyacrylic injection resin with a gelling time adjustable within a range. The material reacts to form a waterproof, elastic and solid gel with good adhesion to both dry and wet substrates. - Permanently elastic
- Capable of reversibly absorbing (swelling) and releasing (shrinking) moisture
- Adjustable gelling times at various temperature ranges
- Very low viscosity compared to water
- Once cured the Product is insoluble in water and hydrocarbons and resistant to alkalis
- Resistant to alternating freeze and thaw exposure
- Injected with a two component pump
|
Usage The Product is designed for: - Sealing of all types of leaking building components in damp or water saturated ground
- Curtain injection
- Consolidation of non-cohesive soils with low permeability
Please note: - The Product must only be used in below ground structures
