The invention relates to a multi-layer structure (1) for producing a
floor covering, comprising at least one
surface layer (2) bonded to a backing layer (3b), the
surface layer (2) and the backing layer (3b) being made from PVC, the multi-layer structure (1) comprising successively and from top to bottom, between the
surface layer (2) and the backing layer (3b), a first woven reinforcement (5a), an intermediate layer (3a), a second woven reinforcement (5b), bonded together, to the surface layer (2) and to the backing layer (3b) by means of bonding
layers (6) in the form of hot-melt films, for example made of copolyamide or
copolyester, or of
layers of crosslinked
polyurethane adhesive, the multi-layer structure (1) comprising a
surface mass of between 2000 and 3000 g / m²,the intermediate layer (3a) and the backing layer (3b) are made from PVC and each comprise:- a thickness of between 100 µm and 200 µm;- between 5 and 25 PCR of
plasticizer, preferably between 6 and 15 PCR of
plasticizer. Figure for the abstract: Fig. 3,
