How Trenchless Pipe Repair and Installation Works

14 Jan


Sewers and the pipework connected to them are often silent heroes in your life. They work away without question, removing the waste from your building. For the most part, pipes and sewers will cause you little worry and you’ll never have to do much with them.


Aside from some regular maintenance where required, of course.


But what happens when you do encounter a problem with your pipework?


Pipes are hidden underground to keep them out of sight. They’re not the prettiest items, so burying them under the surface is the best option…


… but when they go wrong, that can be a real problem.


When a pipe bursts or cracks, the traditional fix is the dig down, extract the pipe, and then replace it with a new one. This causes a lot of issues.


Traditional pipe excavation is:

  • Messy and evasive: Digging into often beautiful or landscaped ground.
  • Slow: Digging up the ground takes time and can sometimes lead to other problems.
  • Costly: Digging up the pipe is only the beginning. What’s above the pipe? That’s a real worry and often costly to move, replace, or repair.


Traditional pipe repairs are littered with problems of their own and although are effective in fixing the pipe, they can cause more problems for the land and building owner.


Now there’s another way…


Trenchless pipe repair is different

Trenchless pipe repair doesn’t require excavation of the ground and huge upheaval of surrounding areas. And it doesn’t cost as much in related work either.


With a trenchless repair we use the existing pipe to guide the new pipe in, and then leave the old pipe right where it is, out of harm’s way and with far less mess.


Here’s how trenchless pipe repair works

  1. Instead of digging the entire pipe out, a specialist team will create two holes in the ground at each end of the pipe, and dig down to it.
  2. A highly-trained team uses specialized pneumatic or hydraulic equipment to ‘force’ a high-density polyethylene pipe (HDPE) into the space where the pipe is currently lying. This material is lightweight and strong and lasts for a long time.
  3. The ‘bursting head’ placed at the front of the pipe will ‘burst’ through the existing pipe, breaking it up and leaving the remnants of it in earth where it causes no harm to the environment.
  4. The HDPE pipe then seamlessly follows the path of the old pipe, fills the gap left and replaces it.
  5. Then the pipe is connected at either end, leaving the watertight and stronger pipe to do its job, whilst avoiding penetration from roots and such threats in future.
  6. The two holes are filled and covered back up, leaving your new pipe and existing pipes hidden and safe 6ft under!



Preparing ahead before trenchless pipe repairs

There is of course a lot of preparation that goes into the simple process above and without professional inspection and professional care, an attempt at replacement could cause more damage that you had to begin with.


Our trained team will use CCTV pipe inspection to find the fault and assess the job before moving any earth, and certainly before performing any excavation.


Assessing the problem with CCTV pipe inspection is much less invasive than digging and gives us the best possible view of the problem without disturbing the pipes and potentially causing more problems.


The benefits of trenchless pipe repairs

The main benefits are clear. The pipes are replaced with minimal disruption and at a lower cost, but here are the big plus points to this style of pipe replacement.


  • Cost-effective: Trenchless repairs mean less digging, less damage, and less to move, replace, and fix afterwards.
  • Cleaner: Trenchless repairs cause less mess. With two simple and clinical incisions your land is disrupted far less.
  • Faster: The trenchless approach saves time. Inspecting and working on the pipe with a trenchless repair system takes way less time than excavating an entire pipe.
  • Higher quality repair: This new technology will leave your pipes with a joint-free repair, leaving you more protected against future leaks in that area.
  • Convenient: With less disruption, this type of repair doesn’t need to involve digging up buildings and roads, or having to close sidewalks or roads themselves.


Save time, money, and hassle – go trenchless!

As you can see from the infographic we’ve created to show you how a trenchless repair works, it involves a lot less disruption and the results are cleaner and more efficient repairs.
