Void filling & contact treatment
Fill inaccessible voids and reinstate support where incomplete contact can concentrate movement, leakage or deterioration.
DURBE designs controlled treatment for voids and incomplete interfaces behind, beneath or around underground structures, including locations where access is limited and broad excavation is impractical.
Re-establish continuity and support
Treatment geometry, material behaviour, pressure and volume limits are selected around the void, structure sensitivity and required outcome.
- Annular and interface void treatment
- Voids behind tunnel linings, station walls and shafts
- Voids beneath slabs and other structures
- Ground–structure contact reinstatement
- Constrained-access and operational environments
Controlled and documented delivery
Pressure, volume, sequence, response and material consumption are recorded and reviewed to manage structural sensitivity and provide evidence of treatment.
Restore contact where it matters—without losing control of the structure or the surrounding ground.
