Belzona 4141 | Magma-Build | Concrete Repair
A lightweight epoxy repair composite for rebuilding damaged vertical and overhead concrete and masonry surfaces. This high-build concrete repair material can be applied up to 12.7 cm (5 inches) thick on vertical surfaces and up to 7.6 cm (3 inches) thick on overhead surfaces without the use of shuttering during cure and only minimal support during the application.
