Resins - Hermes-1K-Inject
Highly foaming 1-component PUR resin Art. No.: HTD-90007
…a highly foaming, 1-component injection material based on polyurethane that reacts strongly upon contact with water.
Further properties
The resin is suitable for pre-sealing or two-phase injection in combination with the HERMES-FlexSeal PUR or the HERMES-Power-Inject series.
Due to its extremely fast reaction time in contact with water and its massive yet fine-pored volume expansion, it is perfectly suited for temporary sealing against pressurized water, as well as for large damaged areas, cavities, and water ingress.
The material forces its way into cracks and construction joints and consolidates loose rock, bedrock, concrete, and masonry.
Fast reaction time – accelerated by contact with water
Large, fine-pored foam structure
No shrinkage
High chemical resistance
Extremely low viscosity
CFC and halogen-free
Tested according to EN 1504-5
Available in 10l and 20l canisters (catalyst available in 1l / 2l canisters)
Special features
- Fast reaction time
- Maximum volume expansion
- Easy to process using an injection pump
- Highly closed-cell, non-crumbly foam structure
- Accelerator is added separately on site = high storage stability
Application
- Suitable as a temporary pre-seal for very large cavities behind a structure
- Successful sealing against infiltrating groundwater
- Very easy application
- Easy handling using a steel packer and a 1K piston pump
