Given its particular composition, it can be cut with a sharp blade (cutter) and welded with simple heat welding tools, thus making it easier to create connections in the course of work.
1 m/m: Use SEALPVC RG 250 BULB welding the two edges of different belts head to head using a leister (manual hot air welder).
Waterproofing of the dynamic construction joints between: raft foundation and the elevation wall, between two raft foundations, between two elevation walls, between the wall and ceiling.
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.
- Apply by hand
Pay careful attention both to the positioning of the waterstop and to any welds. Incorrect positioning could indeed nullify the performance.
Products and accessories to lay concrete casts, with both metal and wooden formworks, to create underground structures in the presence of groundwater, without using additional waterproof layers (sheathes, etc.)
