Understanding the Benefits of Trenchless Pipe and Sewer Repair


When we have a broken pipe or sewer line, our first priority is always to fix the problem as soon as possible. Traditionally, this was done by tearing up large segments of pavements or landscaping to find out the root cause of the problem and then repairing it. This process involved significant cost towards materials and labour, apart from additional expenses to get the property back to its previous state.  

As pipes age, they tend to fall apart because of cracking and blockages. While it is a great idea to have trees in your building premises, tree roots can wreck havoc by destroying the pipes beneath them. Previously, our only option to correct the problem was to dig up the entire area and repair or replace each section of the pipe. Naturally, this technique is often expensive, time-consuming, and labour-intensive.      

Luckily, however, the scenario has changed with the emergence of trenchless pipe and sewer repair techniques. This underground repair methodology is extremely popular because it is less expensive, faster, and environment friendly. Here, the repairing is performed by a team of trained technicians through a process that that eliminates excavation.  

In trenchless pipe and sewer repair, the exact location of the problem is determined by inserting a small camera into the problematic pipe. After pinpointing the root cause of the problem, the technicians dig just one or two access points for the purpose of feeding in the replacement pipe without any hassles whatsoever.  

Pipe bursting, pipe lining, pipe coating are the most common methods of trenchless pipe and sewer line replacement and repair. Pipe bursting involves feeding new pipes through the damaged pipes. A hydraulic or pneumatic bursting tool is used to break up the damaged pipe. On the other hand, in pipe lining, a liner is fed through the existing pipe and then it is inflated and allowed to harden over time. Finally, pipe coating is done for repairing small holes and cracks inside the pipe by applying epoxy. Epoxy is pushed through the pipe using a pipe coating machines. This process also uses a pump, a flexible tube, and rotating resin application brushes.  

Benefits of Trenchless Technology 

There are many reasons why modern day property owners prefer trenchless technology over the traditional methods of repair and restoration.  

  • In trenchless repair, little or no time is spent on digging. This allows repair works to be completed in quick time. In the contrary, the same repair work may take several days when conventional methods are followed.  
  • In many residential and business premises, sewer and pipelines run under expensive landscaping. Excavation causes serious damage to this landscaping, which can be costly to repair. Trenchless technology solves this problem because it requires only one or two small holes at the two ends of the pipe.  
  • Sewer and pipeline repair and replacements can be extremely expensive when traditional methods are used. This cost can be lowered significantly by following trenchless repair because of low labour cost. The cost is reduced further because there is no damage to landscaping and outdoor features.  
  • An underground plumbing system is a close network of water, sewage and gas lines. Trenchless technology allows technicians to complete the repairs in a streamlined manner with minimum risk of hitting another line.
