High-build concrete repair material
The recent Facilities Show saw Belzona showcase a lightweight epoxy repair composite for rebuilding damaged vertical and overhead concrete and masonry surfaces – Belzona 4141 (Magma-Build).
Belzona 4141 can be applied up to 12.7 cm thick on vertical surfaces and up to 7.6 cm thick on overhead surfaces without the use of shuttering during cure and only minimal support during the application.
A solvent free material, Belzona 4141’s non-porous characteristics ensure the repair will not absorb water or chemicals once cured. Generally, concrete must be left to cure for a minimum of 28 days. However Belzona 4141 will achieve a full mechanical cure at 25°C within just 12 hours, and full chemical cure in only 3 days. Its robust properties further ensure excellent carbonation resistance and enable the substrate to withstand even the most extreme weather conditions.
The main application areas for this system include repair of spalled or damaged concrete areas, weathered stonework, window sills, lintels, columns, archways and bridges, refurbishment of decorative moldings and other cosmetic repairs.
