Makpatch HB is a lightweight concrete repair mortar supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a highly consistent, lightweight repair mortar. The material is based on Portland cement, graded aggregates, lightweight fillers and chemical additives and is polymer modified to provide a mortar with good handling characteristics, while minimising water demand. The hardened product exhibits excellent thermal compatibility with concrete and outstanding low permeability properties. The low water requirement ensures fast strength gain and long-term durability.

Recommended Uses

• Reinstatement of large areas of concrete and for small, localised patch repairs
• Engineered for the repair of columns and beams due to a relatively low fresh wet density without slump it can readily be used for vertical and overhead repair work
• Apply in sections up to 70mm thickness in vertical locations and up to 60mm thickness in overhead locations in a single application without the use of formwork
• Build can be dramatically increased by wet spraying.
•Typical achievable thicknesses are 70 – 150 mm vertically and 70 – 110mm overhead, although this will depend on substrate profiles and the distribution of steel reinforcement

Features & Benefits

• No metallic iron to cause staining
• Fast Setting
• Excellent adhesion – High bond strength to substrate
• Lightweight formulation enabling extra high build – up to 70mm
• Reduces the need for formwork
• Can be applied by the wet-spray process for fast, high-build repairs
• Excellent bond to the concrete substrates
• Pre-bagged to overcome site-batched variations – only the site addition of clean water required
