Pipe relining at Imperial Isuzu and Opel Bloemfontein

Problem:
The car dealership was experiencing water damage inside the showroom every time it rained due to the downpipes draining the showrooms roof leaking.
A CCTV camera inspection revealed that two of the 160mm PVC downpipes which run within the showrooms structural columns had holes in them causing them to leak. It seems as though these two pipes were drilled into by contractors when a particular i-beam was bolted and secured to those columns.

Solution:
The car dealership did not want to replace the pipes as the only option would be to surface mount two new downpipes on the outside of the columns which would affect the aesthetics of the building.
The car dealership turned to Nu Flow for a better solution.

Nu Flow technicians relined the two 160mm PVC downpipes from top to bottom using a structural liner to create a new seamless pipe within the old damaged pipe thereby stopping the leak problem permanently. All work was done working from the pipes inlets on the roof and the outlets outside the building thereby causing no damage tot he building.

How it works:
Step 1) Pipes are inspected to identify problem areas and to determine how much pipe is in need of rehabilitation.
Step 2) Pipes are cleaned prior to relining.
Step 3) An epoxy impregnated liner is inserted into the pipe and pulled into position.
Once in position the inflatable bladder is blown up and left inflated until the epoxy resin has cured.
End Result) Once cured the bladder is removed leaving behind a “nu pipe” within the host pipe.

NO chopping open!
NO damage!
NO mess!
