Renderoc LA is supplied as a ready to use blend of dry powders requiring only the site addition of clean water to produce a free-flowing, shrinkage compensated micro-concrete suitable for large volume concrete repairs at nominal thicknesses in excess of 50 mm.
The material is based on Portland cement, graded aggregates and additives which impart controlled expansion in both the plastic and hardened states while minimising water demand. Its low alkali content minimises the risk of alkali-silica reaction. The hardened product exhibits excellent thermal compatibility with concrete.
Renderoc LA is designed for large volume repairs typically in excess of 50 mm deep. The product can be applied in sections generally up to 150 mm thick although greater thicknesses may be achievable dependent on the configuration of the repair location and the volume of exposed reinforcing steel. Consult the local Fosroc office for further information.
