Beschreibung
Zusammenfassung:	The instant invention provides an apparatus and method for renewing and repairing a manhole including the barrel, the plenum, and the chimney, in a single installation to seal off penetration of ground water into the manhole. The manhole repair liner and method utilizes a stretchable liner material which is precut and fused together to loosely approximate the geometry of the manhole. The liner material includes an acid-resistant layer made from an elastic closed-cell polymeric material. Included and fixed to one side or surface of the elastic liner is a felt, or other loosely woven or organized fabric of fibers intended to receive and retain in place a resin, which when cured, fixes the shape of the liner in position.
