Supporting, sealing and water tightening
Our injection and rock consolidation systems are essential for underground stability. Sika provides injection resins for water stopping, void filling, and structural rock improvement. These systems help reinforce weak ground and increase the safety and performance of tunnel and mine operations.
Injection operations cover an extensive range of applications, from waterproofing to crack sealing and ground-rock consolidations. Water inflows in tunnel structures represent major hazards, also hindering and delaying excavation and rifting processes. Sika provides an extensive range of solutions including services and tools to make tunnelling operations safe, fast and dry. Sika injection systems contain powerful technology to consolidate and stabilise the ground to prevent and/or solve any water income and any ground/rock consolidation need.
Synthetic Injections
There are three key success factors to ensure the effectiveness and durability of injection works. The injection materials, the injection equipment and the injection method. These must all be used in the right combination and this is what Sika provides for tunnelling and mining applications including:
- Cavity & void filling
- Soil/ground stabilisation
- Rock mass stabilisation
- Permanent ground consolidation
- Waterstopping – under hydrostatic pressure
- Controlling over-blasting
- Underpinning
