How does trenchless sewer repair work? Most individuals have most likely come across this process but really cannot tell what it entails. Well, this article will assist you with the answers you need. First and foremost, trenchless sewer repair is one of the most common methods to replace underground pipelines that are old or have been damaged. These repairs can be done without digging up the surrounding area, making them more effective to repair pipes than more invasive options such as traditional digging and trenching. These repairs also reduce the time required for a job, which means it takes less time for site owners to receive their services back, improving satisfaction and revenue since clients don't need to stay out of use while their lines are being repaired. The process below demonstrates detailed activities incorporated in trenchless sewer repair work.
Trenchless sewer replacement begins with cutting through the existing pipeline that requires repairs. This process can rely on several techniques, such as using electrical resistivity to determine the path of the existing pipes or sending an electronic signal through existing pipes to detect breaks in material integrity. Once utility locations are confirmed, digging is required to gain access to the section of the pipe that needs replacing. It's during this step that trenchless sewer replacement becomes important.
The second process incorporated in trenchless sewer repair work is pipe bursting. Here, an expander head attached to the end of a hydraulic machine or a gas-powered cutting head is pushed into the existing pipe under high pressure. This causes the original pipe to burst open and release any particles obstructing it. A new polyvinyl chloride (PVC) piping will be used as a replacement material for this step.
Once pipe bursting is done, a camera will be sent through the newly exposed pipeline section to inspect what types of damage need to be addressed during repairs, such as cracks and leaks, and confirm where every area needs attention. The camera also helps measure the existing pipe's circumference so that proper replacement piping can be ordered.
The trenchless sewer repair then continues with the technicians backfilling the excavated section of the old pipeline with soil and installing a new PVC or ductile iron pipe into it, measuring the circumference again to ensure proper size match. As an added layer of protection against future disasters, a plastic lining is installed instead of traditional concrete if clients prefer this as well.
This step involves workers covering up all newly repaired pipelines with caps and restoring any landscaping features, such as greenery and walkway surfaces, affected by the work. They will then mark these areas to inform customers where construction was done and provide important information on utility hole locations along the repaired line.
Afterward, a trenchless sewer repair company's project manager or crew lead will perform a final site inspection to confirm that repairs have been completed successfully, down to every last detail. According to company policy, if clients are satisfied with this outcome, any leftover material needed for future emergencies can be collected from their property after they permit. All workers involved in completing the job also receive surveys asking about their experience while working on-site to help improve services in the future.
Client sites are monitored over time for issues in this last step of trenchless sewer repair work. If there are any tumults or safety concerns, the trenchless sewer repair company will be notified to conduct further inspections and provide possible solutions if needed. They bill clients according to how long they spend working on-site, ranging from a few minutes if necessary up to several hours depending on the variety of problems faced.
Trenchless sewer repair has many benefits that help customers save money in the long run since it doesn't require as much equipment for installation compared with traditional pipe replacement methods – cutting average costs by 50-70%. These repairs also reduce project times by 70%, resulting in savings in labor and revenue lost due to site closures. During emergencies, technicians are also more likely to arrive quickly since there's no need to deal with traffic or find proper equipment. Clients also get the peace of mind knowing that their pipelines are completely safe and back up-to-code once more after receiving fast, accurate trenchless sewer repair services.
