VOID FILLING PERTH
Precision Void Filling: Engineering Stability for Critical Infrastructure
At BMC, we specialise in advanced void remediation solutions that go beyond simple hole filling. Our expert team provides precision geotechnical interventions that protect and preserve critical infrastructure across diverse environments – from rural landscapes to complex metropolitan settings.
Voids represent more than just empty spaces; they are potential risks that can compromise structural integrity. Whether dealing with small cavities or extensive underground collapses, our sophisticated void filling techniques are engineered to prevent progressive damage and ensure long-term stability of essential assets like railway networks, foundations, and critical infrastructure.
Our approach is distinguished by:
- Tailored Material Selection: We meticulously analyse void characteristics, selecting specialised cementitious grouts precisely matched to each unique site requirement
- Advanced Diagnostic Assessment: Comprehensive site evaluation to determine optimal remediation strategy
- Minimally Invasive Techniques: Solutions designed to restore structural integrity with minimal operational disruption
- Proven Performance: Demonstrated success across challenging industrial, mining, commercial and residential projects
Where others see challenges, BMC delivers sophisticated engineering solutions that safeguard your most valuable assets with uncompromising precision and reliability.
CIVIL INFRASTRUCTURE APPLICATION
Here at BMC, we primarily use a technique known as permeation grouting to install grout blocks in the ground. Our proprietary microfine cement is mixed with water and plasticiser and then injected into the ground and is recognised as the most cost effective solution in the Australian market. When voids need to be fill that are surrounding critical infrastructure such as roads, runways, bridge approaches and abutments and railway lines, our microfine cement is the preferred choice as the chemicals in our product prevent shrinkage with curing so no voids are left behind. Our techniques and product have been engineered for quick turn around times to minimise downtime. We understand getting the facilities operational again is of the utmost importance.
We also specialise in decommissioning redundant infrastructure such as old underground pipes, manholes, boreholes and more.
MINING APPLICATION
BMC’s high performance GP Void Fill Grout is an Australian designed and manufactured product. Blended using a range of premier cementitous materials, BMC GP Void Fill Grout is supplied as a ready to use powder that requires only the addition of potable water to create a multi-purpose void fill grout.
Our Void Fill Grout is suited perfectly to stabilise soil by filling voids in tunnels and mines. Although our solution is often required under emergency circumstances, we offer routine void filling solutions to ensure downtime is kept to a minimum. Our grout injection solution reduces the number of potential hazards for mine operators by controlling precarious ground.
VOID FILLING CASE STUDY #1
Here we have footage of grout being injected into the ground under a railway line. Pipes which are not dug up will tend to rust over time and cause the ground to sink and become unstable. By injecting our BMC grout, we can fill these voids to keep the ground from sinking..

VOID FILLING CASE STUDY #2
A recent project took us inside the lift shaft of a four story apartment building in Victoria Park. Upon inspection, it was found that some of the bricks were hollow and the requirements of a lift wall specifies that the wall must be solid because of the weight that it is carrying.
As you can see, our technician is drilling holes in to every 3 bricks down. We knew that our BMC Grout Filling mix would flow down into the necessary bricks below and fill the voids. It is a fast drying and hardening mix which sets in a matter of hours. Once the void was filled, we hammered in a bung so that the mix would not flow out.
BMC pumped 1260 litres of grout into the wall over the course of 2 and a half full days including clean-up.
