How Much Does Trenchless Sewer Line Repair Cost In South Florida Region?
For residential purposes, from $100-$200 per linear foot of lining. It varies by pipe diameter, installation complexity, and length. It also is less expensive to install outside a building than under the building because of the installation method involved. Typically “air-inversion” is used outside, whereas “pull-in-place” is used under a slab. For Commercial purposes, $175-$225 per linear foot. Commercial installation would be high-rise buildings, factories, shopping malls etc. These installations are more complex since pipe downtime, even for just 4 hours, usually has an enormous impact on tenants and can cause much economic impact for any loss of use of pipe. Note also, every trenchless pipe lining company will have a minimum charge in order to mobilize their expensive equipment and trained crew. For more specific costs, go here.
How Strong Is The Pipe Lining?
The pipe liner is a fabric tube made of polyester which is then “wet out” with a 2-part epoxy resin which is mixed together in a certain proportion. In about 30 minutes resin heats up by itself to 180 degrees Fahrenheit due to an exothermic chemical reaction and becomes rock hard.
The resulting new inner pipe liner is so strong that it is a stand-alone pipe, not needing the old exterior pipe for structural integrity. The liner is designed to go under load-bearing footers, roads, driveways etc. Here’s a video of Hugo Forster jumping on a sample of relined pipe with the old pipe removed – he also beats it with a hammer!
