BELTSEAL 110/125 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 110/125 is very quickly applied directly to PVC piping with a diameter between 110 and 125 mm, 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.

The hydroexpansive capacity of BELTSEAL 110/125 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%.
No. 1 BELTSEAL 110/125 gasket for each conduit pipe to be sealed.
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.
Position the BELTSEAL 110/125 hydrofoam gasket centrally in respect of the length of the pipe (using one gasket per pipe).
