Beltseal

Hydroexpansive gasket for PVC conduit pipes in concrete masonry

Beltseal is a gasket “belt” produced with a special hydro-expansive rubber that reacts upon coming into contact with water that increases its initial volume. Thanks to its geometry, Beltseal is very quickly applied directly to PVC piping without additional processing. It hermetically seals any discontinuities that could easily be found in the concrete due to the presence of PVC conduit pipes. In many cases, such discontinuities could pass from one side of the masonry to the other and thus seriously compromise the waterproofing of the masonry itself. There are three sizes available which are respectively suitable for diameter pipes: 70/90 mm, 110/125 mm and 160/200 mm.

Beltseal

The hydroexpansive capacity of Beltseal has been laboratory tested with two different types of water: demineralised and with a highly basic pH (to simulate conditions in contact with concrete). Expansion tests showed a respective change in volume of 300% and 250%.

Fields of application

For underground concrete constructions with conduit pipes, where the wall is in direct contact with the ground and where there are no layers of waterproofing outside the masonry itself: basements, cellars, underground garages, below-ground and cellar environments, etcetera.

Allowed supports

Mode of use

Position the Beltseal hydrofoam gasket centrally in respect of the length of the pipe (using one gasket per pipe).
