Sinkhole remediation
Filling voids and treating the surrounding ground to help stabilise affected areas.
Overview
How it works.
Remediation involves filling the void beneath the affected area with grout, then treating the surrounding ground to help stabilise it.
Understanding what caused the void is part of the work. 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 too.
Used for
- Filling voids beneath affected areas
- Treating the surrounding ground
- Helping to stabilise affected areas
Good to know
Before you start.
- 01
Best suited to sandy soils
Grout injection generally works best in sandy, granular soils that allow the grout to flow between the particles. Clay, silt and other low-permeability materials can restrict its spread, so suitability is considered for each site.
- 02
Small access points
Grout can often be injected through small access points, reducing the need for extensive excavation. Some drilling, removal of paving or localised digging may still be required, depending on access and the treatment area.
- 03
Allow time for curing
The grout needs time to cure before certain follow-on works, such as excavation or additional loading.
- 04
It stabilises, it doesn't lift
Grout injection focuses on stabilising the ground and providing additional support. It does not return a structure to its original position.
