The new Hauff foil sleeves
provide secure connection of entries through the slab to a radon foil, vapour barrier foil or other seal on the slab. The sleeves are suitable for many entries through base slab, as conductors, waste water pipelines, cable duct hoses etc. In connection with a radontight foil the sleeves prevent convection and the resulting ingress of radon gas into the building. The radon sleeves have an excellent adhesive strength and can be installate on-site fast and simply. For all sleeves we advice to use the squeegee, which is available as accesssory and provides an optimal gluing.
