Cempatch HB45 - Reinstatement Mortar
Verified by manufacturer 1 month ago
High strength R4, fibre-reinforced concrete reinstatement mortar.
Application
Suitable for the repair of all types of structural concrete where high strength and extremely low shrinkage properties are required, including:
- Vertical and overhead elements.
- Structural elements in buildings.
- Water retaining structures.
- Industrial plants.
- Bridges.
Deep pockets can be filled in a one application depending on the shape of the pocket and the volume of exposed reinforcement.
Description
High-build, hand/ wet-spray applied, one component polymer-modified and fibre-reinforced structural repair mortar.
Cempatch HB45 is a thixotropic mortar made up of dry powders, selected aggregates, polymers and fibres, which when mixed with water, allows it to be used vertically and overhead.
Features and benefits:
- Provides extremely low permeability to water, carbon dioxide and chlorides.
- Shrinkage compensated, providing long-term dimensional stability.
- Easy to apply. Single component, requires only the addition of water.
- High bond strength, ensuring monolithic performance of the repair.
- Can be spray applied efficiently by the wet spray technique.
- Thixotropic properties allowing extra high build for vertical and overhead applications.
- Contains no chlorides.
- Suitable for internal and external application.
- Water vapour permeable.
- Suitable for use in contact with potable water.
- Easy to finish.
- Cost effective, hand or wet spray applied, and no formwork is required.
- Suitable for use with cathodic protection systems.
- Extremely low permeability, which retards chemical attacks in aggressive environments.
- Non-flammable.
- Complies with BS EN 1504-3, Class R4.
