Case Study - Drain Tree Root Mass Removal

Project – Mass tree roots removal during drainage installation project 
Equipment Used – Prokasro 4.0 unit 
Pipe diameter – 450mm 
We employ a wide range of cutting discs and milling head to make the removal of roots fast and efficient

Tree Root Build Up / Root Blockage in Drains

Despite extensive jetting utilising a chain flail attachment, our client had been unable to remove 3x areas of mass tree root ingress on a large diameter surface water drain. This was during a drainage installation project, however, the sections with root ingress were running underneath a main slip road meaning an excavation was not an option. The project was nearing its end and would have incurred massive traffic management costs for any work in the slip road. 

Remove Tree Root Build up from Drain / Pipe Reline

We trailed our Prokasro 4.0 up a large embankment to reach the Excavation (unable to work from the manhole as it was in the slip road). Following extensive jetting from our client prior to cutting, we managed to remove the areas of mass root ingress with relative ease, ready for our clients to reline the pipework and prevent further ingress. We worked closely with our client throughout the project to ensure they were happy with the results.

Reinstate drain pipe flow after tree root removal

Despite the unusual circumstances of the job (limited access, etc), we successfully removed the root ingress restoring the pipework to full working order while saving our clients a considerable amount of time/money in the process!


How to Deal With Tree Roots in a Drain or Tree Root Drain Ingress
We begin by a site survey, locating the area in the drain or pipe where tree root ingress has occurred. This is in the form of a CCTV drain survey providing a 360° imagery of the problem within the drain interior. In severe cases where tree roots have completely penetrated the drain or pipe and can in most cases be resolved by trimming away the invasive roots and repairing the point at which they’ve entered the drain.
