Trenchless sewer lining is a method used to repair or replace underground sewer pipes without the need for extensive excavation. Instead of digging trenches to access the pipes, trenchless technology involves inserting a new lining inside the existing pipe. This process can help restore the structural integrity of the sewer line and improve its functionality without disrupting the surrounding area or landscapes.
Cost benefits of trenchless sewer lining include:
1. **Less Labor and Equipment**: Trenchless technology requires minimal digging, resulting in fewer labor hours and equipment usage compared to traditional methods. This can lead to cost savings on labor and equipment rental.
2. **Reduced Restoration Costs**: Since there is minimal excavation involved, there is less damage to landscapes, driveways, or structures above the sewer line. This reduces the need for extensive restoration work, saving on additional costs.
3. **Faster Completion**: Trenchless sewer lining projects are often completed more quickly than traditional methods, reducing the overall project duration. This can result in cost savings associated with shorter project timelines.
4. **Long-Term Savings**: Trenchless sewer lining can improve the longevity of the sewer line by creating a durable, seamless new lining inside the old pipe. This can result in long-term cost savings by reducing the need for frequent repairs or replacements.
Overall, the cost benefits of trenchless sewer lining stem from its efficiency, reduced labor and restoration costs, faster completion times, and long-term savings due to the durability of the new pipe lining.
Steps to Trenchless Sewer Repair Installation
- Access points are identified. These could be exterior clean-out fittings, vent stacks, or toilet openings. These access points will be used to video inspect the damaged pipes and will also provide entry and “pull points” for the liner sleeve.
- A video inspection of the pipe is done to pinpoint actual pipe damage.
- An epoxy coated liner sleeve is inserted into the damaged pipe area.
- Sleeve is inflated and forms a new pipe in the damaged area.
- After liner sleeve has cured, follow-up video inspection is done to verify pipe is repaired accurately. The end result is a smooth and seamless “pipe within a pipe”.
