What is Pipe Patch?

Pipe Patch is a Solution for Repairing Damaged Pipes

Pipe patch is a cutting-edge solution for repairing damaged pipes. Drain cleaning can remove obstructions but can't prevent further problems, such as root intrusion. Pipe patching tackles the root cause of the issue, fixing damaged pipes without the need for costly, time-consuming digging, which can cause damage to your home, yard, landscaping, or utilities.

Pipe Patch Repairs Damaged Pipes Without Digging

One of the most significant advantages of pipe patching is that it doesn't require excavation. This means your customers’ property remains intact, and you won't have to deal with the mess and inconvenience associated with digging up their yard or driveway. Pipe patching is especially useful for pipes located under foundations or in other hard-to-reach areas that are inaccessible even with traditional digging.

How Does Pipe Patching Work?

Repair Material

Pipe patching involves the use of specialized materials, including:

  • Fiberglass Liner Material: This material acts as a strong, durable reinforcement for your damaged pipe.
  • Resin: Resin is used to bond the liner material to the damaged pipe and create a secure seal.
  • Bladder: A bladder is inserted into the damaged pipe and inflated to press the liner material against the inner wall of the pipe, ensuring a tight fit.

What is the pipe patch process?

While the specifics of the repair will vary based on which pipe patch system you choose, each installation will follow the same basic process.

Step 1: Prepare the Pipe

Before patching, the damaged pipe must be thoroughly cleaned. This is typically done with a hydro jetter or a flex shaft machine. An inspection with a sewer inspection camera is also conducted to assess the extent of the damage.

Step 2: Prepare the Packer and Perform a Practice Run

A packer, which holds the bladder and liner material, is prepared for installation. A practice run is often performed to ensure that everything is in order before the actual patching begins.

Step 3: Prepare the Packer and Patch and Install

The packer, bladder, and liner material are inserted into the damaged pipe. Once in place, the bladder is inflated, pressing the liner material against the inner pipe walls, creating a new, structurally sound inner surface.

Step 4: Wait for the Curing Process to Complete

After installation, the resin needs time to cure and harden, creating a permanent seal. This curing process can take anywhere from 10 minutes to a few hours, depending on the type of patch system being used.

Step 5: After Curing, Remove the Packer and Inspect with a Sewer Inspection Camera

Once the curing process is complete, the packer is removed, and a sewer inspection camera is used again to ensure that the patch has been successful.
