What Problems can I use Trenchless Pipe Repairs to fix?
Aging Sewer Lines
Most homes built prior to the early 1970’s had residential sewer and drain lines composed of either cast iron or clay. Traditionally you will find cast iron from property drop to beneath the house (generally near the sidewalk). The primary problem seen is cracking and the bottom of the pipe rusting out. Clay pipes were traditionally used from the property drop to the city sewer main. In most areas residents are responsible for the maintenance of their lines from house to the city saddle which is located within 45 cm of the city main. The primary and extremely common problems seen in clay pipes are root intrusion at the joints and cracks.
Root Intrusion
Root intrusion into sewer pipe systems is reported to cause 50% of all sewer blockages. Interference between trees and sewer systems is likely to occur in older systems and in cracked pipes. Factors that contribute to damage include older pipes with joints, shallow pipes, small-dimension pipes, and fast-growing tree species. Cost associated with caring for root intrusion in the past has been expensive and laborious and, unfortunately, is rarely a permanent fix. Trenchless technology creates a seamless pipe which prevents infiltration and exfiltration, restores the structural integrity of the original pipe, and eliminates the joints which weaken and allow root intrusion.
Calcification in Sewer Lines
Over time, calcium deposits from water form a crusted coating called ‘calcification’ which clogs up household pipes and drain lines, especially when hard water is in use. Once pipes are lined with epoxy, calcification can no longer occur because the deposits cannot adhere to the interior walls of the new epoxy barrier pipe.
Ground Movement Affects Sewer Line Integrity
Major seismic activity can cause breaks in sewer and drain lines, but more frequently, minor seismic activity causes cracking and structural damage at the joints. The seamless, “jointless” nature of the PIP method means not only is the existing problem solved, but the new, seamless pipe will avert future problems as well.
