Void Filling in Rothbury
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.
Void Filling for Rothbury Properties
Rothbury sits in the Coquet valley on Fell Sandstone with river alluvium. The rural town's geology is generally stable, but river valley deposits and weathered sandstone can cause localised issues.
Fell Sandstone Group with Coquet river alluvium. Weathered sandstone and variable river deposits can contribute to differential settlement in some locations. Our void filling service is tailored to these local ground conditions.

FAQs
How do voids form under buildings?
There are several causes. Voids can form from collapsed drains, soil washout, dissolved chalk or limestone, old mine workings, or degraded fill materials. In the North East, historic coal mining is a particularly common cause.
How do you detect underground voids?
We use specialist equipment including ground penetrating radar (GPR), dynamic cone penetrometers, and trial pits to locate and assess voids beneath your property accurately.
What materials are used for void filling?
It depends on the void. We use geopolymer resin, cementitious grout, or foamed concrete depending on the void size, depth, and ground conditions. Each material is chosen for optimal performance in your specific situation.
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, with little disruption to your property or daily routine.
