Crack Injection & Pressure Grouting

Crack injection

Crack injection is a highly effective repair technique used to repair cracked concrete, brickwork and masonry where cracks are static, clean and dry. We use ultra-low viscosity materials, which can be injected to fill the narrowest of cracks (up to 0.2mm in width), thixotropic resins or cementitious materials are used for repairing cracks of greater width. Where crack injection is used to seal a leak, Foreva use specialist techniques and repair materials. Find more information about leak sealing here.

Pressure grouting

Placement of cementitious and resin-based grouts can be challenging when the void to be filled is difficult to access or not visible. Material can be injected under controlled pressure to flood voids in the structure and will flow through interconnected voids finding the path of least resistance, restoring structural integrity and preventing future movement. Pressure grouting can also be used to fill redundant drains, sewers and voids under structures.

  • Foreva Concrete Repairs uses pressure grouting on:
  • Masonry structures
  • Brick structures
  • Concrete structures
  • Steel fabrications
  • Basements, shafts, culverts, tunnels, sewers
  • Bridges
  • Carparks
  • Buildings


We use visually sympathetic and traditional materials to preserve and prolong the integrity of historically important structures to ensure future generations can use and appreciate them.

We also offer vacuum assisted grouting where required.
