SEWER REHAB NEAR MASS GENERAL HOSPITAL

Pipe Relining Eliminates Need To Dig Up Old Brick Sewer Near Hospital’s Entrance

Problem: Deteriorated and leaking brick sewer interceptor serving Massachusetts General Hospital and located in front of the ER entrance.

Solution: Quadex Lining System® (QLS) GeoKrete® was applied in areas where CIPP could not be performed due to headwalls and other obstructions. The versatile application options of QLS/GeoKrete allow the non-round sections of the interceptor to be fully restored when there was no other viable option. Traditional CIPP was installed in rounded sections of interceptor.
