Our fully-trained operatives are authorised to use all the leading manufacturers’ injection systems to provide leak-sealing solutions where water ingress is present. They’re experts at pinpointing the exact materials required, and can customise a solution to fit your needs exactly.

We continuously train our staff to ensure we’re always able to offer the latest solutions.

We offer expertise in injection chemicals and application techniques to protect and repair structures against detrimental salts and water, across the following areas:

  • Foundation pit sealing
  • Joint sealing
  • Canalization repair
  • Tunnels
  • Shafts
  • Culverts
  • Piles
  • Tanks
  • Lift pits
  • Basements
  • Manholes
  • Car parks
  • Underpasses


The quick-reaction or PUR injection foam resins (SPUR) are designed for temporarily stopping water. They start foaming within seconds after contact with water and can be customised to individual requirements.


Polyurethane resins offer high flexibility combined with good adhesion. Cracks treated with PU resins remain leak-proof even in cases of crack width modification and dynamic stress. In cases of highly pressing water, for example, in dam constructions or deep foundation pits, polyurethane resins have a durable sealing effect after use of Spurr.


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 fulfills 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.
