What is compaction grouting?

Compaction grouting is the best solution for sagging or dropping ground-level floors and surface beds, as well as foundations that need reinforcing due to excessive settlement. It is a much better alternative to conventional underpinning with improved long-term results.
 
It is a process where cement-like grout is pressure pumped under either the surface bed, or the compromised foundation. The injected grout fills the void and penetrates the soil, both stabilizing and compacting the soil in the process. During void filling beneath surface beds, the pressure created by the grout can often lift the surface bed up to, or close to its original position.
Compaction grouting is the solution that many insurance providers, real estate agents, and engineers prefer to use. Home owners and office tenants rarely need to move out of their premises. It is far neater and comparatively quicker than traditional underpinning or re compacting, and overall it is more cost-effective, offering results that stand the test of time.

COMPACTION GROUTING PROCESS


Compaction can be used:
As an alternative to conventional underpinning, with improved long-term results
To stabilize subsided surface beds (floor slabs on the ground)
To reinforce existing foundations that need to carry additional load

The benefits of compaction grouting are substantial:
Cost-effective solution
Minimal disturbance to plumbing and electrical services, whereas most traditional methods require re-installation
Significantly less intrusive
Quick process reduces discomfort to owners/inhabitants
Improves fill and supporting soil conditions through compaction and cement infiltration
Preferred by many insurance companies, engineers, and real estate agents.
