REPLACING CAST IRON SEWER LINE
Posted by RICH EKWALL on October 22, 1999 at 12:48:06:
I AM LOOKING FOR A METHOD TO REPAIR 4" CAST IRON SEWER LINE WITHOUT REPLACING THE ENTIRE LINE

I AM THE CONSTRUCTION SUPER IN LOVELAND CO WITH AN APARTMENT BUILDING CONST IN 1974.
THE 4" SEWER LINE IS 150' LONG BURIED UNDER 8" CONCRETE SLAB.
THE BOTTOM SECTION OF THE SEWER LINE HAS RUSTED OUT AND I NEED TO REPLACE OR REPAIR
TO KEEP FLUIDS FROM LEACHING INTO GROUND

ONE METHOD IS TO JACK HAMMER SLAB, DIG DOWN TO SEWER LINE AND REPLACE WITH
4" PVC. THAT PROCESS IS COSTING ABOUT $175/LF. I AM LOOKING FOR A METHOD
OF LINING & SEALING THE BOTTOM OF THE PIPE TO REDUCE THE REPAIR COST.

I HAVE 9 BUILDINGS WITH THE SAME PROBLEM. EACH BUILDING HAS APPROX 220 FT OF LINE
WHICH NEEDS TO BE REPLACED. AT $175/LF THAT GETS TOO EXPENSIVE.

PLEASE ADVISE RESOURCES OR METHODS OF SOLVING THIS PROBLEM

THANKS
