- Leaking Retaining Structures – Groundwater ingress through joints, interfaces and defects in diaphragm walls, secant piles and associated linings. Injection locations are selected based on available drawings, construction records and observed water paths.
- Leaking Ground Anchors – Groundwater ingress through or around anchor penetrations where the sealing arrangement has failed or become compromised. Targeted injection is used to intercept and control water around the anchor and surrounding interfaces.
- Failed TBM Launch & Reception Seals – Injection to control significant groundwater ingress following failure of TBM launch or reception seals. Fast-reacting systems can be selected to suit the flow conditions, required travel and available reaction time.
- Leaking Precast Gasket Joints – Injection of leaking joints where precast gaskets are displaced, damaged or inadequately compressed. Applications include segmental tunnel linings, precast pits, chambers and other underground structures.
- Construction Joints & Waterproofing Terminations – Targeted injection of groundwater pathways at construction joints and waterproofing transitions or terminations. Injection can be undertaken behind the structure or directly through the affected interface.
