Abstract
A liquid-tight lining which is resistant to chemical attack for catch reservoirs, containers or the like of concrete. The lining includes a continuous liquid-tight impervious layer provided above the surface of the concrete. To make possible a simple and safe and repeatable testing of the tightness of the lining, a porous intermediate layer is provided between the concrete and the impervious layer. At least one sensor cable having at least two conductors is placed in the intermediate layer in such a pattern that any location of the intermediate layer is not more than a certain maximum distance away from the cable. The sensor cable is connectible to an electrical monitoring unit.
Claims8
A chemical attack-resistant, liquid-tight lining for catch basins, catch reservoirs or similar containers of concrete, comprising a continuous liquid-tight impervious layer of rubber or plastic material located above the surface of concrete, the improvement which comprises a porous intermediate layer of cement or plaster between the concrete and the impervious layer, and at least one sensor cable having at least two conductors placed in the intermediate layer, the cable being placed in the intermediate layer in such a pattern that any location of the intermediate layer is not more than a preselected maximum distance away from the cable, the cable being adapted for connection with an electrical monitoring unit.
