Abstract

Enhanced adherence uncoupling membrane (10), composed of an embossed plastic sheet (101) with recesses facing upwards, bonded on the underside to a base layer (102, 111) made of unwoven fabric, and having integral anchor points (103) exclusively inside the recesses at the bottom, to impart enhanced adhesion compatibility to the plastic sheet. When installing a floor, membrane (10) is interposed between a screed with adhesive mortar and an upper finishing layer, fixed with cementitious adhesive spread on the sheet in order to penetrate the recesses and adhere to the anchor points (103), as a discontinuous bridge that promotes adhesion. The membrane (10) improves adhesion of the adhesive in the recesses, with high picking resistance, and also makes it possible to accommodate expansion and contraction movements in correspondence with the flat portions between bosses, protecting the floor surface or other covering. The system can be manufactured easily and economically using the proposed production procedure.

The studded membrane has one waterproof plastic sheet coupled to one base layer for anchoring the membrane on the laying plane, with studs which protrude from the membrane-plane and are arranged in a matrix with regular center to center distance in such a way to obtain hollow and continuous spaces among them in the form of corridors. A heating cable is retained and placed among the studs. In particular, adhesive curbs are provided to retain the heating cable and are made up of a glue laid in strips on the membrane-plane, in correspondence with the corridors among the studs acting as laying corridors for the glue.

Abstract

The present invention relates to a multilayer membrane for construction (100), adapted to be installed between a wall (8a) of a seat (8) obtained in the ground (9) and a concrete structure (5), comprising: - a first layer (1) of thermoplastic polymeric material, impermeable or substantially impermeable to water; a second layer (2) of thermoplastic polymeric material, impermeable or substantially impermeable to methane gas and/or radon gas and/or volatile organic compounds (VOC), fixed to the first layer (1) and adapted to be positioned, when the membrane (100) is installed, between said first layer (1) and a concrete structure (5).

Abstract

Separating membrane of plastic material, made up of a bossed and waterproof sheet which is coupled with a permeable base layer. The bosses are of the cylindrical type with a double diameter and have such a shape and arrangement as to feature improved adhesion on both faces. The gripping of the adhesive is increased in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber there is an internal crown, which divides it like a necking into two superimposed compartments having the same diameter, wherein the first compartment has a depth amounting to at least ⅓ of the total. A production process for obtaining the membrane is also disclosed.
