Formadrain is Your Perfect No-Dig Solution for Repairing Underground Pipes

Hundreds of miles have been successfully lined with this system since 1994!

Here's Some Key Benefits of the Formadrain No-Dig System for You...

Formadrain is a true no-dig technology. It is a steam-cured, fiberglass and epoxy system that is pulled-in-place through existing pipes. This means it is used to repair underground pipes without digging. With no excavation, it can perform lateral repairs, Lateral-Main-Connection® repairs, spot repairs and process piping repairs.

In addition, the Formadrain system:

  • Has been steam cured since 1994 when it was developed.
  • Has lined hundreds of miles of pipe since its launch.
  • Counts over 40 authorized Formadrain licensees across the United States and Canada.
  • Can repair circular pipes from 2 to 48 inches (50 to 1200 mm) in diameter.
  • Contains Green technology: No Volatile Organic Compounds used (VOC Free)

Formadrain Passes All Tests and Accepted as CIPP Solution for NYDOT!

The New York Department of Transportation, after rigorous testing and evaluation, has approved Formadrain’s design-engineered, no VOC pipelining solution as a FEP (Functionally Equivalent Product) for use by NYDOT.

The decision comes after a Formadrain product demonstration was done in the NYDOT warehouse parking lot in Albany last August.  The demo showed NYDOT engineers and officials every aspect of the Formadrain system from wetout to cure and final video right on the spot and above ground.

The 12″ diameter pipe of corrugated, galvanized steel used in the demonstration was made to simulate numerous difficult pipelining situations which included:

1. a section with a two-foot gap,

2. another section deformed out of round by 20%,

3. a number of punctures in the pipe, and

4. an added section of Sonotube for mechanical testing that also stood for a diameter transition.

NYDOT staff watched as the Formadrain fiberglass liner was wetted out, wrapped around the proprietary Formadrain mandrel and winched into place as in an actual job repair. The liner was then inflated and fully cured by steam pressure after only 50 minutes.

After the liner cooled, a final video of the pipe repair was made and then a Sonotube cross section of the liner and pipe was cut off for testing. NYDOT engineers then took their observations and the demonstration materials to review to make their decision.

The Formadrain® liner passed with flying colors.

If you are looking for a no-dig, trenchless pipelining system, Formadrain is a system you need to investigate. Watch a video of Formadrain in action.

Formadrain Pipelining Demonstration in New York

The demonstration pipe

Aging wastewater pipe infrastructure is a problem and especially in older cities along the East Coast. This past summer, the New York State Department of Transportation (NYS DOT) evaluated the Formadrain system. And the results made it clear that our no-dig method of pipe repair was as superior as it was cost-effective. Our licensee, Towpath […]

Benefits of Pipe Repair Technology

The piping systems that underlie our homes, offices, and other structures are an essential part of our functioning society. They bring us water, remove waste-water, and take our sewage to appropriate treatment centers. Our health and safety depends on these systems working efficiently. When pipes age, they can become cracked and clogged. Pipes running through […]
