KingRep SA150®
Spray applied, high build, one component, cementitious repair mortar for dry mix shotcrete application with accelerated setting.
Overview
KingRep SA150 is a single component polymer modified and fiber reinforced repair mortar with accelerated setting for dry mix shotcrete application. KingRep SA150 is a blend of dry powders, selected aggregates, reinforcing fibers, microsilica and high quality additives when mixed with water will produce a high build, thixotropic, highly resistant, alkali free repair mortar suitable for dry mix shotcrete machine spraying on vertical and overhead
Applications
- Large area repairs for all structural elements in buildings, water retaining structures, industrial plants, bridges, etc
- Repair of fire damaged structures
- Lining and repair of tunnels
- Cathodic Protection (CP) overlays
Advantages
- High early mechanical strength
- Shrinkage controlled polymer modified cementitious repair mortar. Reduces the risk of cracking due to shrinkage and ensures full contact with host concrete and load transfer in structural repair situations
- Easy to apply, single component, requires only addition of water
- Extremely low permeability to water, providing excellent protection to steel reinforcements and host concrete
- Thixotropic properties allowing extra high build for vertical and overhead applications
- Suitable for internal and external application
- Water vapour permeable
- Cost effective, spray applied no formwork is required
- Can be spray applied allowing for rapid application of large areas with minimal rebound
