Void Filling
Underground voids can form beneath buildings and infrastructure due to washout, dissolved materials, collapsed drains, or old mine workings. These voids pose a significant risk of sudden ground collapse. Our void filling service uses controlled injection techniques to safely fill these spaces and prevent further settlement.
Key Benefits
Sub-surface void detection
Controlled injection process
Prevents sudden collapse
Suitable for all void types
Non-destructive method
Rapid completion times
How It Works
Detection
Ground penetrating radar and other methods to locate and map voids.
Planning
Injection plan designed based on void size, location, and cause.
Filling
Controlled injection of grout or resin to fill the void safely.
Verification
Post-treatment scanning confirms complete void filling.
Frequently Asked Questions
How do voids form under buildings?
Voids can form from collapsed drains, soil washout, dissolved chalk or limestone, old mine workings, or degraded fill materials.
How do you detect underground voids?
We use ground penetrating radar (GPR), dynamic cone penetrometers, and trial pits to locate and assess voids beneath your property.
What materials are used for void filling?
Depending on the void size and conditions, we use geopolymer resin, cementitious grout, or foamed concrete.
Is void filling disruptive?
No, the process is minimally invasive. Small injection holes are drilled and the filling material is pumped in under controlled conditions.
