Representative Leak-Sealing Projects
Each case shows the defect, the method and the materials used to achieve a lasting dry result.
Basement Roof-Slab Crack Injection
Pressure injection of an active through-crack in a basement roof slab leaking onto the parking level; AS grout sealed the crack and restored slab integrity.
Basement Wall Seepage Repair
A damp, weeping basement wall treated with routed plugging and cementitious capillary crystalline coating; the room was dried and handed over for fit-out.
Floor Expansion Joint Sealing
A leaking floor expansion joint routed out, fitted with injection ports and filled with flexible grout plus rapid-setting plugging mortar.
Deformation Joint Waterstop Repair
A failed deformation-joint waterstop replaced in function by chemical injection and elastomeric sealing without breaking the lining.
Garage Ceiling Drip Elimination
Multiple ceiling cracks dripping on parked vehicles were injected from the negative side with carefully controlled hole depth to protect the original membrane.
Close-Contact Grout Injection
Dual-component injection directly into a water-bearing crack, delivering grout into the connected pore network until refusal at pressure.
Residential Basement Waterproofing
Negative-side waterproofing of a residential foundation wall, including wall-slab junction and form-tie holes, completed without excavation.
Highway Tunnel Lining Repair
Dripping lining cracks and construction joints in an operating highway tunnel sealed with fast-curing grout during night possessions.
