Abstract
Polymer Rubber Gel is heated to an elevated temperature and sprayed against the exposed rock to form a generally uniform surface. The Polymer Rubber Gel can be sprayed on the rock surface using a heated want coupled to a heated kettle. Then, a layer of I polyethylene is formed against the polymer rubber gel layer. Finally, a finish layer such as concrete, tile, brick or segmental wall block is placed against the outer side of the polyethylene layer.
Claims20
A method of providing a waterproofing and vapor barrier to an exposed rock surface, the method comprising:
- heating a non-curing polymer rubber gel to a temperature to allow the non-curing polymer rubber gel to be sprayed with a spray wand applicator;
- spraying the polymer rubber gel onto the exposed rock surface until a continuous layer of the polymer rubber gel material is formed over the exposed rock surface;
- disposing a layer of polyethylene sheet against the layer of polymer rubber gel, the polyethylene sheet having a first side and an opposing second side, wherein the first side is in contact with the continuous layer of the polymer rubber gel;
- and
- forming a concrete layer adjacent the polyethylene sheet such that the concrete layer contacts the second side of the polyethylene sheet.
A method of providing a waterproofing barrier to an exposed natural rock surface, the method comprising:
- heating a non-curing polymer rubber gel comprising 99% solids to a temperature sufficient to allow the non-curing polymer rubber gel to be sprayed onto the exposed natural rock surface with a spray wand applicator;
- spraying the polymer rubber gel onto the exposed natural rock surface until a continuous layer of the polymer rubber gel material is formed over the exposed natural rock surface;
- disposing a layer of polyethylene sheet against the layer of polymer rubber gel, the polyethylene sheet having a first side and an opposing second side, wherein the first side is in contact with the continuous layer of the polymer rubber gel;
- and
- forming a finish layer adjacent the polyethylene sheet such that the finish layer contacts the second side of the polyethylene sheet.
A method of waterproofing a tunnel formed through rock to define an exposed rock surface, the method comprising:
- heating a non-curing polymer rubber gel to a temperature sufficient to allow the non-curing polymer rubber gel to be sprayed onto the exposed rock surface of the tunnel with a spray wand applicator;
- spraying the polymer rubber gel onto the exposed rock surface of the tunnel until a continuous layer of the polymer rubber gel material is formed over the exposed rock surface of the tunnel;
- forming a continuous layer of polyethylene over the layer of polymer rubber gel, the polyethylene layer having a first side and an opposing second side, wherein the first side is in contact with the continuous layer of the polymer rubber gel;
- and
- forming a finish layer adjacent the polyethylene layer such that the finish layer contacts the second side of the polyethylene layer.
