Eliminate dangerous underground voids and stabilise unstable ground beneath your property with proven injection technology.
Get a Free QuoteProfessional void filling and ground stabilisation to address underground voids, mineshafts, and unstable ground beneath properties.
Underground voids are a serious threat to property stability. Whether caused by historical mining, natural dissolution of limestone, washout from leaking drains, or decomposition of organic material, voids beneath your property can lead to sudden and catastrophic collapse. Our void filling service uses controlled injection of cementitious grout or expanding resin to completely fill underground voids and stabilise the surrounding ground. This is particularly relevant across Lancashire, where historical coal mining has left extensive networks of tunnels and shafts beneath residential areas. Our specialists use ground-penetrating radar and borehole investigations to map void locations before designing a targeted filling programme.
GPR surveys and boreholes map the location, size, and depth of underground voids.
Engineers calculate the volume and type of fill material needed for complete stabilisation.
Grout or resin is injected through boreholes to fill voids and stabilise surrounding ground.
Post-fill investigations confirm voids have been completely filled and ground is stable.
