Flow-Liner® Utilities Systems:

Electrical CIP-Conduit® & Telecom CIP-Conduit®

Flow-Liner® Utilities offers an option to rehabilitate and extend the life expectancy of existing utility conduits and ducts without excavation and demolition. Flow-Liner® offers its non-invasive CIP-Conduit® lining product, which reduces costly electrical & telecommunication grid down time.

CIP-Conduit® (Cured-In-Place Conduit) can be designed and installed according to your specifications and needs. A pre-site evaluation may be performed by one of our trained and Certified Installers. Once the necessary information is gathered, it is submitted to our Technical Design Division. Lining options will be submitted for your review and approval.

• Approved by IAPMO UES UEL-5054 liner for electrical and telecommunications underground conduits.

• Conduit/duct runs from vault to vault

• Lining of a partial conduit or duct section

• Can line through multiple bends in the conduit

• Engineer Tested to ASTM D 648 Standards

• Meets or Exceeds Deflection Temperature Under Load Ratings for underground Electrical Conduit

• Meets or Exceeds ASTM F1216 Standard for the Rehabilitation of Existing Conduits

• American Electric Power Reference Letter for Flow-Liner® (click here)

Flow-Liner CIP-Conduit for Data Centers

Data centers demand reliable underground conduit systems to protect critical power and communication lines. Unfortunately, water infiltration and separating joints often lead to conduit failures that put uptime at risk and create costly repair challenges. Traditional dig-and-replace methods are rarely an option in these secure, space-limited environments. Flow-Liner’s trenchless rehabilitation solutions, including our CIP-Conduit® system, provide a proven alternative. By restoring conduits from the inside, without excavation, Flow-Liner helps data centers extend the service life of their infrastructure, prevent water-related failures, and avoid disruptions to operations. With tailored designs, certified installers, and support from our technical design team, Flow-Liner delivers reliable results where reliability matters most. The following examples highlight how Flow-Liner has helped data centers overcome conduit failures and maintain uninterrupted operations.

Concrete in Arizona Conduits...

A customer in Arizona was having some problems with their electrical conduits. After televising, the issue was quite clear - during the encasement process, the conduits had separated, allowing concrete to fill the conduit. To avoid breaking up the entire concrete encasement and start the project over, a Flow-Liner Certified Installer was contacted. The Flow-Liner Certified Installer's first and most challenging objective was removing ten feet of cement from the conduit with a robotic cutter in a location that was over 100 feet in from the access point. Once the conduit was cleared and cleaned, the CIP-Conduit process could begin. The installer successfully lined approximately 140 feet of conduit -leaving them with a happy customer.

Alabama Data Center

At a brand-new data center facility, a Flow-Liner Certified Installer was called in to address two major conduit failures. The first issue involved a 6” conduit line with concrete filling the first 10 feet. Using a robotic cutter, the team removed the obstruction and restored the line with an ambient-cure liner. A second 6” conduit at the same site was found to have nearly 80 feet of concrete inside. Once again, Flow-Liner used a cutter to clear the blockage and then lined the pipe, delivering a reliable trenchless solution without disrupting construction at the new facility. The customer was pleased that excavation was avoided—saving them from costly delays.

Georgia Data Center

At a Georgia data center, a 4” conduit had been punctured underground, leaving the line filled with debris and broken pipe at the damage point. Fortunately, the issue was only 20 feet in, allowing the Flow-Liner Certified Installer to​​ easily clear the obstructions and clean the pipe. Once the conduit was cleared, the team installed an ambient-cure CIPP liner that extended about three feet past the break, fully restoring the line. The project was completed in just a day and a half, and the customer was very pleased they avoided the costly and disruptive process of removing concrete to access the conduit.
