Trenchless Sewer Pipe Repair

Trenchless Sewer Pipe Repair

Restore Sewer Lines with FORMADRAIN® Without Full Excavation

We use FORMADRAIN® technology to restore qualifying damaged sewer lines without excavating the full length of the pipe. Flexible, high-strength material is inserted into the current pipeline, where it forms a seamless new pipe within the old one. This approach addresses cracks, corrosion, voids, and root-damaged sections while limiting disruption to driveways, landscaping, and other finished areas.

FORMADRAIN® can rehabilitate residential, commercial, industrial, and municipal sewer systems. Because the liner follows the current line, it’s particularly useful where conventional excavation would require extensive property restoration or access is confined.

How FORMADRAIN® Sewer Relining Works

We begin with a comprehensive CCTV sewer camera examination to locate damage and assess the pipe’s condition. If roots have entered through cracks or separated joints, we remove them and any accumulated debris before repairs begin. The inspection also shows where access is needed and whether the original pipe can support a liner.

FORMADRAIN® is typically installed through one or two small access points. A pulled-in-place fiberglass liner containing epoxy resin is guided through the damaged sewer and fitted to its shape. In this cured-in-place pipe system, the flexible liner hardens inside the original sewer, eliminating the need to lay a separate replacement pipe in an open trench.

Steam curing hardens the liner and creates a new corrosion-resistant pipe inside the old line. Curing generally takes about 45 minutes to one hour after installation, although that isn’t the total project duration. Once cured, the liner seals cracks, fills voids, reinforces damaged sections, and restores appropriate flow capacity.

Benefits of Trenchless Sewer Pipe Repair

Minimal excavation: FORMADRAIN® is installed through small access points, avoiding the extensive digging and heavy machinery associated with open-cut sewer replacement.
Reduced restoration work: Limiting excavation can reduce the need to rebuild landscaping, replace sections of driveway, or repair other finished areas above the sewer line.
Faster completion: Repairs can frequently be finished in a single day, depending on pipe condition, access, and scope.
Long-lasting materials: The seamless liner resists corrosion and root intrusion, two common sources of recurring sewer line damage.
Less property disturbance: Reduced excavation limits displaced soil, construction waste, and disruption around the work area.

For residential sewer systems and larger networks, the liner can conform to bends and irregular pipe shapes. This makes the method useful for lines in confined areas or locations that are difficult to reach through conventional excavation.

Pipe Relining vs. Pipe Bursting

Pipe relining and pipe bursting are separate trenchless methods. FORMADRAIN® pipe relining creates a new pipe inside the sewer line, retaining its original route while sealing and reinforcing damaged areas from within.

Pipe bursting replaces the old pipe instead of lining it. A bursting head breaks or splits the pipe while pulling a new one into place behind it. The method usually requires a launching pit and a receiving pit rather than a continuous trench, and it can accommodate a larger replacement pipe when increased capacity is required.

The appropriate method depends on the pipe’s structural condition, damage, location, and required capacity. A CCTV sewer camera examination provides the information needed to determine whether relining is suitable.

Frequently Asked Questions

Pipe condition, material, access, and the extent of the damage determine whether trenchless repair is appropriate. These answers address common questions about suitability, installation, durability, and cost.

How Do I Know If My Sewer Pipe Is a Good Candidate for Trenchless Repair?

Many cracked, leaking, or root-damaged sewer lines qualify. After a camera inspection, our technicians determine whether the pipe is structurally suitable for FORMADRAIN® or another repair method would provide better long-term results.

How Long Does Trenchless Sewer Pipe Repair Last?

FORMADRAIN® creates a durable, corrosion-resistant liner designed for long-lasting performance when properly maintained.

Will Trenchless Sewer Repair Damage My Landscaping?

Repairs are completed through small access points whenever possible, helping preserve yards, driveways, and landscaping.

Can Trenchless Sewer Repair Fix Pipes with Tree Root Damage?

Yes. After removing the tree roots and clearing debris, we can seal cracks and reinforce the damaged section, helping resist future intrusion and restore proper wastewater flow.

How Long Does a Trenchless Sewer Repair Project Take?

The schedule depends on the pipe’s condition, length, accessibility, and the preparation required. After the camera inspection, we provide a project-specific timeline.

Is Trenchless Sewer Repair Less Expensive Than Traditional Excavation?

It can be. The total cost depends on the repair itself and the excavation or property restoration that can be avoided.

Can Trenchless Technology Repair Commercial & Municipal Sewer Lines?

Yes. We assess the condition, access, and operating requirements of each system before recommending a repair method.

What Types of Pipe Materials Can Be Repaired Using FORMADRAIN®?

The technology is often compatible with clay, cast iron, concrete, and certain plastic pipes. A sewer camera inspection confirms the material, its condition, and the appropriate repair approach.

Will I Be Able to Use My Plumbing During the Repair?

Water use may be temporarily restricted while the liner is installed and cured. Before work begins, we explain what to expect and provide clear instructions to minimize inconvenience.

Why Should I Choose FORMADRAIN® Instead of Replacing My Sewer Pipe?

FORMADRAIN® restores structural integrity through small access points, preserving more of the finished areas above the sewer line while creating a long-lasting sewer pipe repair.

What Affects Trenchless Sewer Repair Cost?

Cost depends on the pipe’s condition, the length and scope of the damaged area, access requirements, and the preparation needed before lining. The estimate also accounts for excavation and property restoration that the method avoids. We assess these factors before preparing a project-specific estimate.
