The project consisted of waterproofing on the forging of a parking deck in a new Leroy merlin centre which was built in Majadahonda. We prepared the surface by mechanical sandblasting and epoxidic primer, and the expansive joints were treated with hypalon bands. We then spray the two component poliurethane membrane at high temperature, very recomended in these kind of jobs for its elasticiy, its continuity as it has no joints and becase it is completely adhered to the surface forming a coniunuos lining.
Above this first waterproofing lining we spread two layers of geotextile and a thermosealed PVC sinthetic line.
Above our two waterproofing systems, a concrete surface was formed to make the parking lots and the traffic lanes.
