VOID FILLING
Advanced void filling solutions to stabilise ground beneath properties, preventing collapse and restoring safe, solid foundations.
WHAT IS VOID FILLING?
Void filling addresses underground cavities that form beneath buildings due to washout, dissolved limestone, former mining, collapsed drains, or decomposed organic material. These voids can cause sudden and dramatic subsidence if left untreated, potentially leading to structural collapse.
HOW IT WORKS
Geopolymer resin or cementitious grout is injected through small-diameter holes drilled into the ground. The material flows into voids, expanding to fill cavities and consolidating surrounding loose soils. Real-time monitoring ensures complete void filling without over-pressurising the ground.
KEY BENEFITS
OUR PROCESS
Ground Survey
Ground-penetrating radar or other geophysical methods to map void locations and extent.
Drilling
Small injection holes drilled to reach void locations with minimal surface disruption.
Injection
Expanding resin or grout pumped under controlled pressure to fill voids completely.
Monitoring
Real-time level monitoring ensures the ground is stabilised without lifting beyond target.
Verification
Post-treatment survey confirms voids are filled and ground is consolidated.
