摘要： A patch is provided and described that can be used with the installation of a cured-in-place structural liner in a conduit when the conduit has protrusions into the conduit. The patch is made with similar material to the liner, or felt, and is impregnated with epoxy. The patch may be shaped to more closely match the anticipated curve of the outer surface of the liner. Tools for the installation of the patches, a method of use, and tools for measuring the quality of the installation of the patch before the installation of the structural liner, are also described.
