From 0.15 to 0.30 cartridges of FLEXSEAL 300 for each linear metre to be sealed, depending on the geometry of the cavity.
Formation of airtight seals at connections, holes, cavities, cracking, formwork blades etc.; execution of seals in the connection between pipes and masonry; Material to assist in laying both traditional and hydro-expansive waterstop profiles.
The application surfaces should be clean, free of incrustations, crumbling and non-adhering parts, dust etc.
Cut the tip of the cartridge with a cutter so as to allow the extrusion of a sealant kerb of at least 8 mm in diameter (to ensure that the sealing is both efficient and hydro-expansive). FLEXSEAL 300 must be placed laid in properly confined sections and covered with at least 6 cm of structural, shrink-resistant mortar GROUT 6 (castable) or REPAR TIX (thixotropic).

- Nitro thinner
- Prefabricated concrete

Do not use FLEXSEAL 300 as a simple silicone. Totally unconfined expansion would detach it from the support, thus making the sealing redundant.
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.)
