Common problems / 01
Cracked walls
Where ground movement is contributing to cracking, grout injection may help address it.
Understanding the problem
What you need to know.
What cracking can mean
Cracks in walls can have a number of causes. Where movement in the ground beneath the foundations is contributing, the cause should be understood before deciding on a solution.
How grout injection can help
Grout injection can help address ground movement contributing to cracking, where the treatment is suitable. By strengthening the ground beneath existing foundations, underpinning helps manage settlement and support the structure.
In suitable soils, the grout spreads between the soil particles and hardens, creating a stronger, more stable mass. It generally works best in sandy, granular soils.
What it won't do
Existing cracks generally require separate repairs. Grout injection also does not return a structure to its original position. It stabilises the ground and provides additional support.
When to involve an engineer
Some projects require an engineer to assess the problem and specify the treatment. This is particularly relevant where a building is moving. Our site observations do not replace an engineering assessment.
