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
What causes voids to appear beneath a property?
Yes, there are multiple causes. Underground voids typically develop from collapsed or leaking drains, natural dissolution of chalk and limestone, old mine workings, soil being washed away over time, or the breakdown of poorly compacted fill materials.
How are underground voids found?
Yes, we use advanced detection methods. Ground penetrating radar (GPR), dynamic cone penetrometer testing, and targeted trial pits accurately locate, map, and assess voids before any remedial work begins.
What filling materials do you use?
Yes, we offer several options. We select the most appropriate material for each situation — geopolymer resin for precision work, cementitious grout for larger voids, or foamed concrete where high-volume filling is required.
Will void filling cause disruption to my property?
No, very little. The process involves drilling small injection points and pumping material in under controlled conditions. There is no excavation, and most jobs are completed within a day.
