Always ahead of the market. And we go on like that by producing accessories for waterproofing sheets and finishing elements for roofs and terraces. The products are compatible with waterproofing membranes, based on bitumen, PVC and polyolefin. Drainage roof drain, roof vent pipes, paving supports, pipe fittings, prefabricated corners and fixing.
