- PRODUCT PROPERTIES:
➢ Flexible and has good elasticity.
➢ Good chemical resistance.
➢ Available in many different forms for different joints.
➢ Easy to apply.
- AREAS OF APPLICATION:
MC-Waterstop HP is used to fill expansion joints and stop joints in the following concrete structures:
➢ Basements
➢ Water tanks
➢ Swimming pools
➢ Tunnels, underground sewers
➢ Retaining walls
➢ Hydroelectric dams,…
- APPLICATION NOTES:
MC-Waterstop HP positioning: MC-Waterstop HP is positioned in the middle of the structure before pouring concrete. It can be positioned between two formwork sections or between reinforcement layers via small holes on MC-Waterstop HP with metal wires, so that MC-Waterstop HP does not move during concrete pouring.
Concrete pouring:
➢ MC-Waterstop HP can only perform its function when both sides are in the concrete and are not bent.
➢ Concrete must be thoroughly tamped to avoid honeycombing.
➢ Note: when pouring concrete near the MC-Waterstop HP position, avoid the situation where the pressure on both sides of the MC-Waterstop HP is not equal, pour evenly on both sides of the MC-Waterstop HP so that the MC-Waterstop HP does not fold.
➢ Before pouring the second layer of concrete, clean the MC-Waterstop HP surface, for example: dirt, adhesive concrete mortar layer, etc.
Welding:
➢ Use an MC-Bauchemie electric welding knife to weld on site. Heat both ends of the MC-Waterstop HP simultaneously with both sides of the welding knife until the PVC becomes evenly molten.
➢ Remove the welding knife and immediately join the two ends of the weld together, holding the joint firmly until the heated PVC cools and solidifies.
➢ Check the weld for gaps or imperfections, re-weld if necessary.
