Abstract
A system for impregnating a liner with a curable substance enables the liner to be used to repair or refurbish an underground conduit. The system includes a vacuum pump having a vacuum line communicably connected thereto. The vacuum line has a vacuum inlet formed therein. The vacuum line supports the liner such that the liner covers and encloses the inlet. A supply of a curable substance has an applicator line connected thereto. The applicator line is proximate the vacuum line and has a discharge port located proximate the liner supported on the vacuum line. An applicator pump moves the curable substance through the applicator line and discharge port onto the liner while the vacuum pump draws a vacuum on the liner.
