PROFILE WIDTH SELECTION

The width of waterstop depends upon the thickness of the concrete and positioning of the reinforcement. The
thickness of the concrete should be greater than or equal to the width of the waterstop profile. Refer to your
Design Engineer for further clarification and approval.

successfully cure the rubber compounded joint.
2. Cut each end of the Sure-Stop Rubber Waterstop that are to be joined, square and straight.

surface.
4. Clean the Sure-Stop Rubber Waterstop surface with solvent cleaner using a paint brush. Apply liberally

5. Liberally apply 1 (one) coat of CORKJOINT Rubber Adhesive by brush up to 2” wide all around the waterstop
and on the ends. Wait for adhesive to go tacky before the next step.
