Whilst there are many reasons why drainage pipes will need to have structural liners integrated into them by professional drainage relining companies; the three listed below are typically the most common:
Aging Cast Iron Pipes
Many of the residential and commercial drainage systems contain cast iron pipes that were installed before the 1980s. The life span of cast iron is around 25-30 years. Over time, the bottom of horizontal cast iron pipes gets channelled away (or disappear entirely) due to the constant flow of water through the ferrous pipe.
Pipe Corrosion, Calcification and Scale Build-Up
As well as the aforementioned channelling, corrosion, calcification, and scale build-up are all part of the aging process of pipes. Whilst high pressure water jetting will deal with this problem on a short-term basis it will not stop the pipe from failing in the long-term.
Tree Root Intrusion
If tree roots are found to be the cause of a drainage pipe clog or stoppage then it is usually an indication that there is a hole or crack somewhere within the pipe.
Drainage pipe lining basically involves installing an appropriately sized structural ‘sleeve’ inside a pipe. This structural liner can be as short as two feet in length or as long as is necessary to structurally line and rehabilitate a complete drainage system. Once a faulty pipe has been suitably cleaned and prepared the pipe liner can be installed and cured in place within just a few hours.
