WEBAC® HIS
WEBAC HIS is a hybrid injection resin used as a reactive component for large-volume cement grouting and holds National Technical Approval. It is characterized by rapid strength development and cures even underwater to form a stabilizing and sealing material. The resin is used to secure Foundation Pits and tunnel structures, as well as for subsoil stabilization and void filling.
- Stabilization of foundation pits and tunnel systems
- Tunnel face consolidation and pre-injection, especially in front of TBMs, umbrella injection
- Backfilling of annular gaps in tubbings
- Fast water stopping and sealing in case of water ingress (depending on cement type)
- Stabilization of washed-out soil and disintegrated rock mass; default zones
- Ground stabilization
- Slope stabilization
- Stabilization of soil areas in earth- and damworks
- Filling of cavities and voids
- Consolidation of karst and unconsolidated rock, gravel and crushed rock layers
Properties
- Polyurethan-based injection system
- Reactive component for large-scale cement injections, adjustable to many types of cement
- Extremely econonomical
- Very fast strength development
- Aquatic and terrestrial environmental compatibility (column experiment)
- Additional fire load negligible with high cement content
- Cures even under water
- Suitable for cutting and planing
