Rockmax Tunnelstop is a hydrophilic rubber sealing material strip for sealing joints in precast concrete tunnel segments. It‘s designed for especially high water pressure. Rockmax Tunnelstop is formulated from high grade elastomeric material and hydrophilic resins. It will swell (more than 300%) when contact with water to perform internal pressure inside the joints against the water leaks.
AREA OF USES
Rockmax Tunnelstop designed especially for precast concrete tunnel segments with and including underground precast structures, steel and concrete joints and various civil engineering construction projects.
APPLICATION AND INSTALLATION
The grove joints must be clean and free from oil, grease, dust, dirt, mould oil, cement paste and other contaminants. Ensure the concrete joints is sound and dry. No crack, damage, holes on concrete surface. Repair must be made prior to install waterstop strip. The water could enter from those damaged concrete.
Apply Rockmax Tunnelstop Adhesive along the joints. Allow adhesive to curing and become tacky. Apply the Rockmax Tunnelstop strip to the substrate. Use rubber hammer to finish the strip lightly. Connection joints by butted together only. Do not overlap. Keep the installed waterstop strip in shade and do not exposed to rain water or ground water.
