Curtain Injections

Our staff are fully-trained in all the leading manufacturers’ injection systems, specialising in sealing methods that use pressure gel injections (curtain walls).

With their low viscosity and high elasticity, the products we use are ideal for sealing structural components with ground contact. Water-like viscosity means very high penetration into mineral surfaces, with a waterproof, solid elastic gel forming once it’s cured. This gel offers high tear resistance and good adhesion to mineral surfaces both dry and wet.

In our experience, this method of stopping water ingress is very effective in these areas:

  • Basements and partial basements
  • Floor slabs
  • Tunnels
  • Foundation pits
  • Canal systems and shaft installations
  • Abutments of bridges and wing walls
  • Locks
  • Underground car parks
  • Retaining walls
  • Expansion joints, especially in defective sheets and tapes
  • Connection joints between old and new structures
  • Canal connections

ACRYLATE GELS

These gels are designed to make new sealing surfaces (curtains) in foundation soils that have direct contact with the building component or within the structure. With a low viscosity, acrylate gels are ideal for sealing structural components with ground contact. On interaction with water, the gel swells and fulfils requirements for ground water hygiene. Areas of application include sealing tunnel, shaft and canal systems, abutment and wing walls in bridge constructions and sealing partially non-basement buildings.
