Makpatch HB 85 Ultra

Makpatch HB 85 Ultra is a polymer modified high ultimate strength structural high build fibre reinforced repair mortar with corrosion inhibitor.


Makpatch HB 85 Ultra is a concrete repair mortar which is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a highly consistent, high strength repair mortar. The material is based on the latest advances in cement, fillers and chemical additives technology 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 water repellent properties. The low water requirement ensures fast strength gain and long-term durability.
