Cempatch HB - R2 High Build Repair Mortar
Verified by manufacturer 2 days ago
High build, non-structural polymer-modified repair mortar.
Application
Suitable for the repair of all types of concrete requiring low permeability and where high compressive strength is not critical, including vertical and overhead elements.
Description
Single component, lightweight, high build, polymer-modified, cementitious repair mortar designed for use in concrete repair works.
Cempatch HB is mixed with water to produce a thixotropic mortar suitable for vertical and overhead applications.
Features and benefits:
- Thixotropic properties allowing for extra high build for vertical and overhead applications.
- Excellent low sag properties.
- Can be spray applied efficiently by the wet spray technique.
- High bond strength, ensuring monolithic performance of the repair.
- Low permeability to water, providing excellent protection to steel reinforcement and host concrete.
- Compatible with non-structural concrete of compressive strength 15–25 N/mm².
- Contains no chlorides.
- Non-flammable.
- Complies with BS EN 1504-3, Class R2.
