Curtain Injection

Curtain Injection

Injection behind a structure to form a barrier against water ingress.

The problem

The external face of a below-ground structure cannot be accessed to install or repair waterproofing.

Injection is carried out from the inside face to form a barrier behind the element.

Typical applications

  • Basements and below-ground car parks
  • Retaining structures
  • Tunnels and shafts

Selection considerations

  • The ground conditions behind the structure
  • Drilling pattern, injection sequence and pressure
  • Whether a follow-up internal treatment is required

Key limitations

  • The extent and continuity of the injected barrier cannot be fully verified from the inside face.
  • Method and product selection must be confirmed with Ozone for the specific structure.
