We manufacture our fiberglass reinforced waterstop couplings in both Schedule 40 and Schedule 80 soc x soc sizes from 3/4" to 24". Fabricated with premium fiberglass and resin over PVC, our waterstops include a formed, fiberglass flange. More reliable than heat-welded PVC, our fiberglass waterstops will create a durable hydrodynamic waterstop when encased in concrete.

Fiberglass waterstop couplings are a fraction of the cost of brass and are non-metallic, so no grounding is needed. Tie wire holes allow fitting to be secured tight and level during floor pour.

If you have a custom requirement, send us your drawings and we will quote you prices for a custom fabricated waterstop coupling!
