Sinkhole &
Void Filling
Experts

Rapid, non-invasive stabilization to address subsurface voids before they escalate.

Informed Methodology

Long-Term Solutions
Without Excavation

Sinkholes form when erosion or water movement removes subsurface soil, creating voids beneath the surface. As support is lost, the ground above can settle or collapse without visible warning.

Early Warning Signs
of a Sinkhole

Along with on site assessment and detailed visual observation of the area, Terratech's 3D Scanning techniques and analysis can show advanced warning signs for informed remediation.

Formation Process

Early Sinkhole Formation is Invisible

Compaction Grouting

This technique uses a low-mobility, thick grout injected under high pressure to displace and densify loose granular soils, increase bearing capacity, and fill voids.

Progression Increases Risk of Collapse

Permeation Grouting

This process injects low-viscosity grout into soil without disturbing its natural structure, filling the pores to increase bearing capacity and reduce permeability. It is suitable for granular soils like sand and gravel.

Injected Polyurethane Stops Degradation

Chemical (polymer) Grouting

This involves injecting a chemical solution, such as an expanding polymer or grout, to consolidate or lift concrete slabs and stabilize soil. Expanding polymer fills voids and compacts soil.
