FIDIA - Reinforced bitumen sheets for roofing


Elastoplastomeric polymer-bitumen waterproofing membrane reinforced with stabilised rot-proof, wowen glass fibre mat.

The FIDIA membranes are made up of distilled bitumen, selected for industrial use, with elastomeric and plastomeric polymers added to obtain a phase inversion compound whose continuous phase is formed by polymers in which the bitumen is dispersed, where the characteristics are determined by the polymeric matrix and not by the bitumen even though this is the most consistent ingredient. The performance of the bitumen is therefore increased along with the durability and the resistance to high and low temperatures while the already optimum adhesive and impermeable qualities of the bitumen remain unchanged.


The long lasting strength, elasticity and stability at high and low temperatures make FIDIA POLYESTER and MINERAL FIDIA POLYESTER membranes ideal for use as a single or multi-layer waterproofing systems for new building work or for refurbishment:

  • On all sloping surfaces: on flat, vertical and curved surfaces.
  • On different types of substrates: site-cast or prefabricated concrete substrates, on metal or timber roofing, on the most common thermal insulation used in the building trade.
  • For the most varied uses: terraces, flat and sloping roofs, dielectric and acid-proof coatings and walls in contact with the ground.

The high dimensional stability of FIDIA/V makes the membranes suitable for combining with elastomeric, elastoplastomeric and plastomeric membranes reinforced with “non woven” polyester fabric. to form double layer waterproofing systems. FIDIA/V can also be used in a single layer as a vapour barrier.
