DESCRIPTION

MITCHBAR 1020 is in the form of rubber strips and is made of high performance modified polymer materials. The swelling action is the result of the contact between water and hydrophilic groups which are part of the MITCHBAR 1020 molecular structure. Expansion of the water stop creates a positive seal against the face of the concrete joint and prevents the entry of water into the structure through the protected joint. It has controlled expansion rate to prevent damage to freshly placed concrete. It retains original shape even after repeated expansion and contraction. The swelling properties are unaffected by long term wet/dry cycling and provides an effective water seal throughout the life of the structure.

USES

MITCHBAR 1020 can be applied against existing concrete and is simply installed by nailing or using a bonding adhesive. In contact with water, hydrophilic strips react and swell by up to 300% of their original dimensions to form a compression seal. Hydrophilic strips are suitable for installation in low movement construction joints as well. MITCHBAR 1020 is used primarily for foundation wall slabs, slabson grade, precast wall panels, manholes, pipe connections, box culverts, sewage and drainage structures, Tunnels, drinking water tanks and all other concrete structures where water tight joints are required.
