Resin Injection Void Filling Service
Empty spaces beneath floors? Ground settlement concerns? Gaps under concrete? We specialise in fast and effective void filling using expanding polyurethane resin that stabilises ground and prevents future settlement without excavation or disruption.
Why Voids Form Beneath Properties
Soil Erosion
Water runoff, leaking drains, or underground streams can wash away soil beneath concrete slabs and foundations, creating dangerous voids.
Decomposing Organic Matter
Buried vegetation, tree roots, or organic materials decompose underground, leaving empty spaces where solid ground should be.
Damaged or Collapsed Drains
Broken drainage systems allow water to wash away supporting soil, creating voids along pipe runs beneath buildings.
Mining Subsidence
Historical mining activity creates underground cavities that migrate upward, eventually forming voids beneath surface structures.
Frost Heave Damage
Repeated freeze-thaw cycles can displace soil and create gaps beneath concrete surfaces in susceptible areas.
Construction Vibration
Heavy machinery, pile driving, or demolition work nearby can cause soil compaction and void migration.
Settlement of Made Ground
Previously disturbed ground, infilled land, or reclaimed sites are prone to ongoing settlement and void formation.
Construction Vibration
Heavy machinery, pile driving, or demolition work nearby can cause soil compaction and void migration.
Subsurface Decomposition
Buried organic matter decomposes over time, leaving underground voids that cause settlement and foundation collapse.
Signs You May Have Voids
If you’ve noticed any of these warning signs, void filling could prevent costly structural damage and protect your property investment.
Hollow Sounds
Floors or concrete that sound hollow when tapped or walked upon.
Sinking or Settling Slabs
Concrete surfaces that have noticeably dropped or become uneven.
Cracks in Concrete
Especially cracks that appear suddenly or continue to widen over time.
Gaps at Building Edges
Visible spaces between concrete slabs and building foundations or walls.
Uneven Floor Levels
Interior floors that have developed noticeable slopes or height differences.
Drainage Issues
Water pooling in areas where it didn’t previously, suggesting ground settlement.
Why Choose Resin Injection for Void Filling
Fast Completion
Most void filling projects are completed in a single day, with the resin expanding and curing within minutes of injection.
Minimal Disruption
No excavation, no demolition, and minimal disruption. Small injection holes are drilled and sealed, leaving surfaces virtually unmarked.
No Planning Permission Required
Our resin injection technique doesn’t require planning permission, saving you time and administrative headaches.
Cost-Effective Solution
Void filling costs a fraction of excavation and replacement methods, with no spoil removal or material disposal fees.
Environmentally Friendly
Our resin formulations are eco-friendly and won’t contaminate soil or groundwater.
Long-Lasting Results
Provides permanent stabilisation with decades of proven performance and comprehensive warranty protection.
Precision Application
Engineers can control expansion precisely, filling voids completely without over-lifting or damaging existing structures.
Immediate Load Bearing
Once cured, treated areas can bear full loads immediately—no waiting periods or phased loading required.
Insurance Backed Warranty
Comprehensive coverage that provides long-term protection and peace of mind for your property.
