Polyacrylic elastic injection resin for permanent watertight sealing

Sika Injection-307 is a polyacrylic, 3-part acrylate based injection resin with a very low viscosity and adjustable reaction time

  • Provides a passivating environment for embedded steel reinforcement
  • Adjustable curing time between 10 and 50 minutes
  • Permanently elastic
  • Capable of reversibly absorbing (swelling) and releasing (shrinking) moisture
  • Very low viscosity comparable to water
  • After curing the Product is insoluble in water and hydrocarbons and resistant to alkalis
Usage
The Product is designed for:
  • Crack and joint injection
  • Injection of SikaFuko injection hoses to seal construction joints
  • Sealing water-bearing cracks and voids
  • Sealing all types of leaking building components in damp or water saturated ground conditions
  • Sealing leaks where there is some minor movement
  • Sealing drainage pipe joints, that are covered with damp or water saturated soil
  • Injection repair of damaged waterproofing membranes (single and double layer systems)
 
Advantages
