Claim:
1. A method of providing a restorative waterproofing membrane to a distal side of a concrete substrate that includes a crack through the substrate from a proximal side to the distal side, the method comprising: forming a first hole through the concrete substrate from the proximal side that communicates with the distal side; forming a second hole through the concrete substrate from the proximal side that communicates with the distal side, wherein the second hole is laterally displaced from the first hole along the proximal side such that the crack lies between the first hole and the second hole; coupling an injection valve to the first hole; coupling a distal end of a heated hose to the injection valve; coupling a proximal end of the heated hose to a heated hopper, wherein the heated hopper includes a pump; introducing a polymer rubber gel material into the heated hopper; elevating the temperature of the polymer rubber gel material in the hopper until the polymer rubber gel material can flow under pressure through the heated hose; and pumping the polymer rubber gel material at the elevated temperature through the injection valve until the polymer rubber gel material can be observed exiting the second hole.
