Welcome to all the basic need to knows on Metro Rod’s non-invasive drain repairs using drain linings and patching. 

Drain lining and patching is an advanced technique we here at Metro Rod Edinburgh use to repair a range of defects within the drainage system. You may be thinking that with the majority of your drains lying under the ground a drain repair will require digging down and causing a lot of disruption to your property. Fortunately for you, Metro Rod use non-invasive techniques via drain lining. 

We have 2 different methods for drain lining that provide a reliable long-lasting solution. So whether it’s a cracked and leaking pipe or general wear and tear you can be assured you are getting a good fix. After the situation has been assessed our engineers will decide which method to use. 

  1. Ambient Cured Lining - this is used for partial or full relining of sewers and drains to cover the defects, perfect for small sites such as a domestic property. The actual repair is done with resin which is manoeuvred into place using pressure, which then self-cures in ambient temperatures. 
  2. Heat Cured Lining - this method is more common for industrial sites and large commercial premises to line the full length of the drains and pipes. The resin in this method is installed using the inversion method. When it is in place water is heated up inside the pipe so that the curing process can start.

What Are the Benefits of Drain Lining?

The benefits of using these methods are fairly simple, it is less invasive than old fashioned method of excavating to reach the repair site and therefore much less expensive and time consuming. It means our engineers do not need to spend time digging out the drain which means you are spending less on man hours and equipment costs. This will also be much nicer for you as you don’t have to deal with the disruption caused by excavating.

Unfortunately there are some cases when a drain lining just wont work and we may need to excavate the problem. In the cases where a section of the drain needs to be replaced we will need to dig down. This would happen if we are dealing with a collapsed drain.
