PVC waterstops are highly elastic waterproof profiles that are used in concrete structures, positioning them as recovery and expansion joints, thus ensuring perfect hydraulic sealing and the ability to absorb mechanical and natural stresses.
Specifically, the SEALPVC SF 250 BULB profile is made of high-quality thermoplastic vinyl resins with the addition of a particular and specific plasticizer.
The profile has excellent performance characteristics and is highly resistant to:
The flexibility of SEALPVC SF 250 BULB is high even at low temperatures and its mechanical characteristics remain unchanged over time.
Given its particular composition, it can be cut with a sharp blade (cutter) and welded with simple heat welding tools, thus making it easy to create connections during construction.
Waterproofing of dinamic construction joints between: raft foundation and the elevation wall, between two raft foundations, between two elevation walls, between the wall and floor, resting on foundations under the shoring.
Bind with iron wire the side flaps of the waterstop to the steel plates provided, in order to position it and secure it in a central position with respect to the casting to be made. Proceed with the casting operations, ensuring it does not bend nor move from the seat identified.

1 m/m: Use Sealpvc SF 250 Bulb welding the two edges of different belts head to head using a leister (manual hot air welder).
Pay careful attention both to the positioning of the waterstop and to any welds. Incorrect positioning could indeed nullify the performance.
