Build to Scale: The Future of Small-Diameter Rehab

Trenchless technology has always had a place in the field, but in recent years, one thing has become crystal clear: Small-diameter rehab isn’t so small anymore.

Today’s trenchless solutions for small pipe are rewriting the rules. Compact, high-powered gear now tackle everything from assessment and descaling to cutting and reinstatement. All of these tasks can be performed through a small access point or cleanout.

Cured-in-place pipe (CIPP) lining isn’t just for mainlines anymore — it’s showing up in vertical stacks, in-building repairs, vents, rain leaders, and branch lines. Because these solutions are low disruption, they’re used in college dorms, apartment buildings, hospitals, and historic properties. As applications expand, it’s no surprise that contractors are seeking solutions that are more efficient and less invasive.

“With the growth of the small diameter market, it is critical to have access to the necessary equipment and technical support needed to do the work.” said MaxLiner senior vice president Connor Collier. “Compared to some other trades, small diameter rehabilitation has a low barrier of entry. The work is scalable, and more is being invested in training and protocol to ensure installers’ success. If you’ve got the drive and the right partners to help you along the way, this is a business you can build.”

Demand is surging, and savvy contractors are stepping up and growing their businesses. Knowing what solutions are on the market today — and how to get the most out of your investment — is essential for success.

Technology That Opens Doors

What makes today’s small-diameter rehab so compelling is the sheer variety of tools and methods available to installers. From initial cleaning to final curing, there’s a full workflow of solutions designed specifically for no-dig repairs:

High-speed drain and lateral cleaning systems use cable- or shaft-driven tools to prep lines for inspection or lining. They clear scale, roots, fats, oils, and grease.
