And when jobsite issues arise, our professional installers and engineers know how to address them before they turn into problems. With more than 60 professional installation crews in North America, we can respond whenever and wherever you need us.
How much do your processes cost?
Because every job involves different pipe conditions, our rehabilitation experts analyze project requirements on a case-by-case basis, recommending the technically viable solutions that cost the least. It is always best for you to discuss your needs with us before we can offer you a price quote. Please contact us to discuss your pipe problem.
How does the cost of Insituform® compare with that of open cut?
The Insituform® process is usually less expensive than dig and replace methods of sewer repair, even for everyday problems. When you consider the avoided costs when rehabilitating rather than replacing sewers, Insituform® delivers even greater value. When you choose Insituform®, you minimize inconvenience to local businesses, residents and commuters because projects are completed quickly and with virtually no disruption to streets and neighborhoods. Because digging is not required, environmental damage is usually non-existent. Restoration of pavement or landscaping is not needed, and utility services are not impacted. So before you dig, call Insituform® and find out how affordable it is to rehabilitate your sewers.
