Description :

Cempatch HB50 is a one component polymer modified and fibre reinforced, high build, hand / wet-spray applied, structural repair mortar. Cempatch HB50 is a blend of dry powders, selected aggregates, fibres, polymers and corrosion inhibitors which when mixed with water produces a thixotropic mortar suitable for vertical and overhead application. Cempatch HB50 can be applied in a single application of up to 80 mm thickness in vertical applications and up to 60 mm thickness in overhead applications without the need for formwork. Where higher thicknesses are required, sections can be achieved by the use of formwork or can
be built up in layers. Cempatch HB50 incorporates proven Migrating Corrosion Inhibitor technology to provide high durability repairs,
which minimise further corrosion to steel reinforcement. Longterm protection is provided by the migration of corrosion inhibitor molecules from the mortar into the structure. These are adsorbed onto the reinforcement to form a protective film which inhibits both anodic and cathodic sites, effectively reducing corrosion activity to a negligible level. Adjacent concrete is also protected from incipient anode corrosion in chloride-contaminated concrete.

Advantages :

• Easy to apply. Single component, requires only addition of water.
• High bond strength, ensuring monolithic performance of the repair.
• Contains corrosion inhibitors for additional protection of reinforcement.
• Can be spray applied efficiently by the wet spray technique.
• Shrinkage controlled polymer modified cementitious repair mortar.
