PVC waterstop
Extruded PVC profile cast into movement and construction joints. Holds back head pressure while the joint keeps moving.

Polybar+ Superswell 30×30 mm
The heavy section — deep joints and sustained head.
A hydrophilic profile fixed to the first pour before the second one goes in. On contact with water it swells against the concrete either side of it and closes the joint under pressure.
Because it is surface-fixed rather than cast through the section, it suits joints where reinforcement congestion leaves no room for a conventional PVC waterstop — and it can be run around penetrations a rigid profile cannot follow.
