Uretek Void Filling

Voids and sinkholes are a serious and often unseen issue beneath critical infrastructure and buildings. If left unchecked, they can lead to ground instability, causing structures and surfaces above to move or collapse.

Our Uretek Void Filling service — delivered using Geobear's geopolymer injection technology — provides a fast, precise, and non-disruptive solution that restores ground stability before failures occur.

Infra culvert void

Where Uretek Void Filling is applicable

Uretek Void Filling addresses ground failures and void conditions including disused pipes, tunnels, culverts, and voids created by burrowing animals.

Voids cause a loss of support beneath concrete, leading to visible settlement and cracking at the surface.

Uretek Void Filling can be used across:

Roads and highways
Airport runways, taxiways, and aprons
Rail track beds and embankments
Manholes, culverts, and buried utility chambers
Public buildings and open spaces
Slab settlement and cracking

Unstable ground

Burrowing animals and similar causes create hidden ground movement. Uretek Void Filling restores stability by filling the resulting voids.

Sinkhole formation

Visible holes or sudden ground collapse requiring immediate remediation.

Water erosion

Soil loss from poor drainage or flooding creates voids beneath infrastructure and slabs.

Benefits of Uretek Void Filling

Minimal disruption - A no-dig approach allows assets and sites to remain operational throughout the work.

Pinpoint accuracy - expanding resins fill every cavity and compact surrounding soils, ensuring complete fill and stabilisation.

Rapid results - materials cure within minutes, enabling hand-back within hours rather than days.

Lower carbon footprint - up to 75% less carbon than concrete-based alternatives.
