General/Root Barriers Testing & Soil Sampling CCTV Jetting/Cleaning Repairs

Job Vacancy Details


Drain Scan have developed a lower impact method of root barrier installation using a slot trenching machine designed and built by Bob Freeborn, specifically for use with the Dendro-Scott root barrier system.

As shown in the photos and videos below, installation of the root barrier material is carried out by digging a narrow trench of 170mm wide up to 4.3 metres in depth.  Where site and soil conditions allow its use, this method substantially reduces site impact and cost of site restoration.
