Following a blockage clearance it's quite often necessary to have a CCTV survey carried out to and determine the exact cause so that appropriate measure can then be taken to avoid repeated problems.
It may be just a general maintenance issue where drainage hasn’t been cleaned. Scale and silt deposits form which require a straight forward cleaning by either high pressure water jetting and/or heavy duty electro-mechanical machining.

However, if the cause of the problem is more extensive, then a full written report can be generated, utilising insurance approved reporting software, accompanied by a full video report and site plan together with photo’s of the exact defects along with comprehensive costs to carry out the required repairs.

With the latest surveying technology, we are now able to traverse around toilet pans, trapped gulley and numerous 45 degree bends.
In the event that major structural defects are discovered, one of technical team will evaluate the video footage and decide on the most suitable and cost effective repair available.
Various repair options are possible dependant of the type of defect applicable. Repairs can range from conventional excavation, insitu-structural lining works, or point patch repairs.
If the problems are noted as tree root infiltration, water driven cutting equipment can be used to gently trim back surplus roots, sufficient enough so that lining procedure can be implemented to prevent any future growth.
