The Problem
Aging Sewer Lines
Most structures built prior to the early 1970’s had 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 structure to the
city saddle which is located within 18 inches of the city main. The primary and
extremely common problems seen in clay pipes are root intrusion at the joints
and cracks. Older lines we not designed to withstand today's high concentrations
of grease, harsh chemicals, and abrasive materials and are failing at alarming
rates.
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 pipes and drain lines, especially when
hard water is in use. We clean out all the calcification and debris that has
degraded the performance of your pipes using a high pressure water
jetting process and pneumatic tools if required. 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.
