Installing or replacing a trenchless sewer line is a modern and efficient method that minimizes the need for extensive excavation and disruption to the surrounding area. A step-by-step breakdown of how our team replaces or installs a trenchless sewer line system is listed on the page below.

Trenchless Sewer Line Method

The Process

Initial Assessment and Planning

The process begins with a comprehensive assessment of the existing sewer line system. Contour Inc. will inspect the site, identify any issues or damages, and determine the most suitable trenchless method for installation or replacement. Factors such as the length, depth, and condition of the existing sewer line are taken into consideration.
Preparation and Access Points

Before the installation process begins, any necessary preparations are made. This may involve shutting off the sewer line, clearing the work area, and ensuring access to the sewer line through strategically created entry points or small pits. The entry points serve as access for the trenchless equipment.
Pipe Insertion

Trenchless methods for sewer line installation or replacement typically involve two main techniques: pipe bursting and pipe lining.
1. Pipe Bursting: In pipe bursting, a bursting head is attached to the new sewer pipe and inserted into the existing sewer line. The bursting head breaks apart the old pipe while simultaneously pulling the new pipe into place. This method creates a new, seamless pipe path as the old pipe is fractured and pushed into the surrounding soil.
2. Pipe Lining: Pipelining, also known as cured-in-place pipe (CIPP) lining, involves inserting a flexible liner impregnated with resin into the existing sewer line. The liner is then inflated and cured, adhering to the inside of the old pipe, effectively creating a new pipe within the existing one. This method is suitable for repairing minor damages or sealing cracks and leaks.
Connection and Testing

Once the new sewer line is in place, our team will make the necessary connections to ensure proper alignment and sealing. This involves connecting the new sewer pipe to the main sewer system and any lateral lines. Thorough testing is then conducted to ensure the new sewer line is functioning properly and free from leaks or blockages.
Site Restoration

After the installation or replacement is complete, the work area is restored. The entry points or small pits are backfilled, and any disrupted landscaping or hardscaping is reinstated. This may involve filling excavated areas, reseeding grass, replacing plants, or restoring other landscape features.
