POLYMAT Pool: Classic Swimming Pool membranes and Pond Liners in sky blue and various RAL colors

POLYMAT Pota: Membrane certified for potable Water tanks, Reservoirs and Containers for var. liquids


POLYMAT Roof -R as a single-ply membrane for:

Ballasted roofing systems and Roof Gardens (Green Roofs)

System membrane for inverted roofs, using a separation layer (i.e. polypropylene fleece 120 g/m²), where adjoining surfaces have incompatible chemical properties (e.g. extruded and expanded polystyrene boards, bituminous surfaces)

For ease of detail works (i.e. flashings, joints) use high UV resistant & fire retardant POLYMAT Roof UV-HM (homogenous) and for UV-exposed upstands and connected UV exposed surfaces POLYMAT Roof UV-R (reinforced).


Bitumat was founded in 1984 but its roots go back to 1975 when the founders became involved in the roofing waterproofing industry as dealer and applicator in Saudi Arabia for a major manufacturer from the U.S.A.
