Abstract
An industrial floor, comprising at least one covering layer on a new or existing concrete base, said covering being not bound to the concrete base and obtained from a composition based on at least one hydraulic binder, said floor further comprising, between the concrete base and the covering layer, from the upper face of the concrete base: (a) a smoothing layer enabling the flatness/roughness of said upper face to be less than 2 mm under a 2 meter rule; (b) on the smoothing layer, at least one separating layer for preventing the first covering layer from adhering to the smoothing layer on the base; (c) on the separating layer, at least one covering layer having a maximum of 30 mm.
Claims22
An industrial, floor comprising at least one covering layer on a new or existing concrete base having an upper face and a lower face, said covering layer being not bound to the concrete base and obtained from a composition based on at least one hydraulic binder, said floor further comprising, between the concrete base and the covering layer, from the upper face of the concrete base:
- (a) a smoothing layer enabling the flatness/roughness of said upper face to be less than 2 mm under a 2 meter rule;
- (b) on the smoothing layer, at least one separating layer for preventing the covering layer from adhering to the smoothing layer on the base;
- (c) on the separating layer, at least one covering layer having a maximum thickness of 30 mm.
