01-04 / Common problems
- 01Cracked wallsWhere ground movement is contributing to cracking, grout injection may help address it.
- 02Sinking or settling groundSettlement beneath foundations, or ground that's sinking, can often be stabilised with grout.
- 03Leaning or failing retaining wallsGrout injection can provide additional backing and support to existing retaining walls.
- 04Voids & sinkholesUnderground voids and sinkholes can be filled with grout and the surrounding ground treated.
Before you decide
Worth knowing.
- 01
It stabilises, it doesn't lift
Our grout injection work focuses on stabilising the ground and providing additional support. It does not return a structure to its original position.
- 02
Find the cause
Long-term performance depends on the cause of the original problem, so issues such as leaking pipes or poor drainage may need to be addressed as well.
- 03
Best suited to sandy soils
Grout injection generally works best in sandy, granular soils. Clay, silt and other low-permeability materials can restrict its spread, so suitability is considered for each site.

When an engineer is needed
Some projects require an engineer to assess the problem and specify the treatment, particularly where a building is moving, a retaining wall is failing, or excavation is planned beside an existing structure.
