Description:

Renderoe HB, a lightweight concrete repair mortar, 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, 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 water repellent properties.

The low water requirement ensures fast strength gain and long-term durability.

Uses:

For the reinstatement of large areas of concrete and for small, localised patch repairs. Renderoc HB is alkaline in nature and will protect embedded steel reinforcement. It is specifically designed for vertical and overhead high-build applications. The mortar is suitable where high-strength, as well as exceptional chloride and carbon dioxide resistance is required.

Important note: this mortar is approved for use with Norcure realkalisation. When using it in conjunction with this method, the concrete bonding primer should be an OPC:water slum. Polymer bonding agents should not be used. No steel primer should be applied. Refer to your local Parchem sales office for further advice.
