About DAPEK
DAPEK Dach- und Abdichtungstechnik GmbH, based in Asten, Austria, has been working for over 20 years on high-quality and practical EPDM sealing solutions. The offering includes sealing systems for flat roofs, balconies, terraces, green roofs, pitched roofs, buildings and facades. Single-layer, installable EPDM sealing membranes such as RESITRIX as well as ALUTRIX as a vapour barrier are processed; the membranes can be welded at any point and are applied flame-free without an open flame. A focus is on refurbishment: bitumen roofs can be renovated by direct adhesive bonding to the old bitumen, and sheet-metal roofs receive a weatherproof and hail-resistant sealing system. Further applications include base/plinth sealing with a secure transition from concrete to timber, as well as root-resistant, ecologically harmless green roof waterproofing. Reference projects include, among others, the Lentos Art Museum in Linz, the courtyard complex of Schlägl Abbey, the Wimbergerhof in Lasberg, the Aviva Single Resort & Spa and the Schwarzenstein hut at 3026 m in the Ahrntal valley.
