INSTALLATION

​

PVC waterstop are installed prior to concrete placement to ensure proper positioning. Make sure PVC waterstops is in good condition, clean and free from oil, dust and dirt. 

 

Split formwork is required for installation ribbed or dumbbell type PVC waterstop. Split formwork allow half of waterstop be positioned within the first pour and projecting into the second pour. The centerline of waterstop must be aligned with centerline of concrete joint. The split form must be leak proof to prevent leak of fresh concrete. 

 

To fix the waterstop in place we recommended to use steel clip or built on-site hog ring to hang waterstop with steel wire off adjacent reinforcement. This is to prevent waterstop from folding over during concrete placement. 

 

Ensure that PVC waterstop is clean prior to concrete placement. Pour concrete carefully and vibrate around waterstop for prevent air bubbles, holes or air pockets or honeycombing.  

 

SPLICING PROCEDURE

​

All transition, intersection, end joint must be splice by butt. PVC waterstop is easily join using spicing iron or heat blower machine. The end of waterstop must be cut using industrial grade cutter or machine saw cut. Uniformly melt the both side of pvc waterstops using spicing iron or heat blower machine. Hold the two pieces of waterstop together immediately. Hold until the material has cool down (approximately 30-60 second).

 

Alternatively splice method please consult Technical services.
