ROCKMAX RUBBERSTOP
RUBBER WATERSTOP


 

INTRODUCTION

Rockmax Rubberstop is a rubber waterstop based on natural rubber. It used to prevent passage of water through construction and expansion joints. It can be used to all type of concrete structures such as water tank, waste water tank, sewage, channels, swimming pools, culverts, etc. Rockmax Rubberstop are also available in other polymers such as CR (Chloroprene/Neoprene), EPDM rubber.

AREA OF USES

Rockmax Rubberstop can be used for stop passing of water through concrete structures such as water tanks, waste water tanks, retaining walls, underground structures, dams, reservoirs, box culverts, diaphragm walls and etc.

    PROCEDURE COLD JOINING OF RUBBER WATERSTOP

    1. Cut waterstop ends straight and true using sharp knife or saw blade.
    2. Clean and roughen the ends of the waterstop using abrasive paper and or wire brush 100mm from the end. Drill the hole for insert steel bolts.
    3. Clean the roughen surfaces using the clean cloth and water. Allow to dry.
    4. Apply a thin coat of adhesive to all surfaces, as the adhesive becomes tacky insert the end of the waterstop into the fitting. Be sure to insert to the full depth of the fitting and hand press together.
    5. Clamp all bonded areas using the steel bolts in to the holes and let set for 2 hours.
    6. Do not pull the bonded area for at least 24 hours.
    7. Bonds will reach maximum strength in approximately 14 days.
