The IZOELAST P5 DIN bitumen waterproofing membrane is used an intermediate layer in two- or more layered flat roof systems which are protected by a UV-resistant membrane or as protection layer in roofing systems under heavy protection, especially there, where strains because of movements of the construction are expected. It is also used in single-layer waterproofing systems against dampness and in double-layered horizontal waterproofing systems exposed to pressurized water (hydrostatic pressure). The membrane is protected on both sides by polymeric sheeting.
