Abstract
A cladding for a partially-overhanging substrate, such as a tunnel wall which comprises in sequence, from the tunnel wall, a drainage means, a sprayed polymeric membrane and a final layer of concrete. The cladding gives an effective cladding in conditions where the tunnel walls suffer from running water at the time of cladding, is easier to apply and requires less material.
Claims35
A cladding on a partially-overhanging substrate which comprises, from the partially-overhanging substrate inward toward the interior of the cladding the following elements:
- (a) a drainage means selected from the group consisting of:
- (i) a plastics mesh to which is applied to that side remote from the substrate an at least partially waterproof layer;
- and
- (i) two layers of geotextile wherein a waterproof film is between the two layers of geotextile;
- (b) a sprayable waterproofing membrane;
- and
- (c) a layer of concrete;
- wherein there is optionally a layer of concrete between the partially-overhanging substrate and the drainage means (a).
A method of providing a waterproof cladding on a partially-overhanging substrate, comprising the application to the substrate the following elements in sequence:
- a drainage means selected from the group consisting of;
- (i) a plastics mesh;
- and
- ii) two layers of geotextile wherein a waterproof film is between the two layers of geotextile;
- a waterproofing membrane, applied by spraying;
- and
- a layer of concrete.
A cladding on a partially-overhanging substrate which comprises, in sequence starting from the substrate;
- a drainage means, wherein the drainage means is a plastics mesh;
- a waterproofing membrane which has been applied thereto by spraying;
- and
- a layer of concrete.
