Vertical Drain Lining
Re-line leaking rain drains & vertical sewer stacks in high rise condos.
High rise condominiums have vertical sewer pipes, vertical rain drains and vertical vent stacks. In South Florida these pipes, usually made of cast iron, rust profusely in the damp, salty environment. After about 30 years, they are ideal candidates for vertical pipe lining which is permanent pipe replacement without the need to excavate walls and floors, and tenants can stay in their condos without disruption or relocation.
Pipe Lining Is Quicker, Less Costly, Less Destructive and Less Disruptive Than Pipe Replacement
The new inner pipe lining is installed conveniently from the rooftop and requires no wall excavation and drywall replacement. No cabinets have to be removed, no mirrors need replacement, no decorations have to be restored, and no workers need to enter the condos. Usually these projects are completed during summer when the “snow birds” are out of town.
How Does Vertical Pipe Lining Work?
First the vertical stacks are cleaned using high pressure water jetters, or more often, mechanical wire brushes which prevent condo flooding during cleaning. The debris is collected or washed out of the bottom of each pipe. Then the distance of pipe lining is measured from the rooftop using a pipe video inspection camera, and an exact length of pipe lining “sock” is cut to reline the inside of the pipe.
The pipe lining “sock” is then wet out or saturated with a special, odorless self-hardening epoxy resin and the sock is then installed into the pipe. Air pressure is used to inflate the sock against the pipe wall for three hours during the epoxy curing time. After three hours the pipe is put back into service.
