Drainage systems can be compromised by various things including blockages, damaged pipes, tree roots, fatbergs, and even pests. Historically, investigations and repairs required the digging up of pipes to identify any issues. However, there are now several alternative ways to investigate and repair without excavation.
1: Drain descaling
If you are suffering from recurring blockages in your drains, it could be caused by a severe build-up of limescale in the pipes which is narrowing them, reducing the space for the water flow, and leading to blockages.
Descaling is an excellent way to remove build-ups of minerals, rust, or other debris from pipes/drains.
2: Jet cleaning
Cleaning your drain pipes using high-pressure water jets is a very effective way of clearing debris and even tree roots – all of which can potentially cause issues in the system. Jet cleaning is a very quick and non-disruptive method, and is especially good for dealing with stubborn blockages.
3: CCTV drain surveys
One of the key technologies that facilitates identifying drainage issues without excavation is CCTV.
A series of small high-resolution cameras can be attached to wires and fed into the drainage system to enable real-time footage to be captured and transmitted back to the surveyor or engineer. This provides detailed images of the inside of pipes and means that problems such as blockages, cracks, and collapsed pipes can be identified.
This method is able to identify the cause and exact location of most issues and saves time, money, and disruption. Around 40% of drainage contractors always use this method to check drains before carrying out work.

4: Drain relining
This fairly recent method offers a no-dig way of repairing cracks, leaks, and some smaller structural problems. It involves the insertion of a resin-coated flexible liner which, when it cures and hardens, essentially creates a pipe within a pipe.
