Usage

For injecting cracks in concrete and masonry wherever there is a need to consolidate a structure or exclude water and air from contact with reinforcement. Due to its thixotropic nature it can be injected into open ended cracks where depth and quantity of resin need to be controlled. Crack widths of 2 mm or greater can be filled. Ideal for small scale repairs on site. Can be used for insitu or precast concrete elements.
