Bitumen and Membranes
These are plastomeric waterproofing membrane modified by top quality APP polymers and reinforced with non-woven polyester.
Membranes are installed by propane gas torch by melting the waterproofing compound with burner. Surfaced should be primed with cold applied bituminous primer before laying. Sheets are placed on the roof and then aligned by overlapping the edges by 10cm on the sides.
MODIFIED BITUMEN MEMBRANES: This type of roofing is an evolution of asphalt roofing. It is made from asphalt and a variety of modifiers and solvents. There are several ways of connecting pieces of this material. In a heat application process the seams are heated to melt the asphalt together and create a seal. There is also a cold-applied adhesive application process, and some self-adhesive forms of this system. This material is also referred to as APP or SBS depending on the blend of polymers used to modify the bitumen.
