Vertical Stack Lining
Corroded drain stacks in apartment and commercial buildings can be relined floor to floor without opening every wall.
The details, in plain English.
The vertical stacks that carry waste through a building often hide in walls and chases. When cast iron stacks leak or corrode, repairing them the old way means opening walls on every floor and displacing tenants.
Stack lining works from the roof or lower access points, descaling and relining the stack in place. Branch connections are reopened with robotic cutters. It is a proven way to renew risers in apartment buildings, hotels, hospitals and offices.
