Bituminous products

Bituminous membrane is the most established waterproofing material available — and, at the same time, the one with the greatest number of variants that appear identical on the quotation. Two rolls of 4 kg/m² may differ in modifier, reinforcement, flexibility and coating, and have a difference of fifteen years in service life on the same flat roof. At ARGYNET, we stock a range of ESHA (Alfa-Alfa Energy) bituminous waterproofing materials, organised so that selection is based on technical criteria rather than weight. SBS elastomeric membranes with flexibility down to -20°C for flat roofs subject to thermal stress and in cold regions. APP polymeric membranes for high temperatures and intense solar exposure, with EN 14695 certification for selected types, where bridge deck waterproofing is required. Self-adhesive cold-applied membranes for substrates where open-flame application is prohibited — XPS and polyurethane boards, timber, metal. Special root-resistant membranes with Preventol® B5 for green roofs and planters, as well as perforated vapour pressure release layers. Plus the liquid-applied coatings and accessories that complete the system: water-based and solvent-based primers, joint sealants, fixing strips, guttering and vents. The bituminous membranes bear the CE marking in accordance with EN 13707 (flat roofs) or EN 13969 (basements), with a Declaration of Performance and technical data sheet available for download from each product page. Liquid-applied coatings and accessories are accompanied by the relevant technical data sheets and, where applicable, by a European Technical Assessment. Trade supply with technical support: checking primer compatibility with the substrate, selecting reinforcement and coating according to the intended application, calculating roll quantities based on actual coverage — and delivery to construction sites nationwide.
