MASTERFLEX 801 is a multi-component, solvent free, water swelling vinyl ester based injection system that cures to form a flexible yet solid material with an excellent bond even to wet substrates. Depending on the degree of availability of moisture, the cured system swells reversibly up to 120% of its volume to act as an effective and permanent seal against ingress of water.
MASTERFLEX 801 is recommended for sealing cracks, joints and crevices in concrete, rock and masonry to prevent water ingress. Applications include injection of:
cracks, fissures and seams in the rocky strata of mines and tunnels
stabilised cracks and non moving joints in structural concrete
concrete construction joints using Masterflex 900 (see separate data sheet)
