Abstract
A method of preventing water from escaping through cracks in a waterway or reservoir includes the steps of forming a membrane of a laminate of butyl sheet with a layer of synthetic fibres bonded thereto, lining the waterway or reservoir with sheets of this membrane, sealing the joins between adjacent sheets and spraying high density concrete onto the exposed fibre layer.
Claims7
A method of lining a waterway or reservoir, which method comprises the steps of laminating a layer of flexible and liquid impervious material with a layer of fibrous material to form a flexible base lamination, applying the lamination to cover at least part of the surface of the waterway or reservoir with the flexible and liquid impervious material adjacent the surface and the fibrous material situated on the side of the flexible and liquid impervious material opposite the surface, and applying to the fibrous material a thin exterior layer of high density concrete to form a key with the fibrous material underneath.
A method of lining a waterway or reservoir, which comprises laminating a layer of a flexible and liquid impervious material with a layer of fibrous material to generate a flexible lamination, then applying to the exposed surface of the fibrous material a thin layer of high density concrete in keyed relationship with the fibrous material to form a resultant block of lining, and applying the resultant block to cover part of the surface of the waterway or reservoir with the flexible and liquid impervious material against the surface of the waterway or reservoir, repeating the said steps successively and effecting a joint between adjacent blocks to form a continuous lining for the waterway or reservoir.
