Injection

The great variety of different injection methods allows us to deal with damage patterns in buildings and structures on an individual basis. Injection methods are primarily used in concrete or masonry structures, where the challenge is to rehabilitate man-accessible sewer sections, shafts, basements and other structures.

The main technical options are:

• Blocking of infiltration water:
  High-pressure injection of highly reactive polyurethane foam

• Grouting of cracks and joints:
  High-pressure injection of epoxy, PU or acrylate resins

• Masonry stabilisation and gap filling:
  Low-pressure injection of cement paste

• Sealing of buildings and structures:
  Grid injection of acrylate gel
