The Polygomma EPDM Roofing Membranes were recently used to re-roof the PVDF coated gutters of the Doha Metro.
The original EPDM waterproofing material did not perform as required. Polygomma made mock application videos to train the waterproofing contractor.
The earlier EPDM roofing membrane was removed, surface was cleaned, and then Polygomma EPDM Roofing Membrane was installed as per customized application procedure.
After installation, the water ponding test was completed successfully.
