the DRAINLOC® pipe offers superior flexibility, providing greater resistance to handling damage in the field by absorbing ground settling and earth movement. Its joints minimize issues such as infiltration, exfiltration, and root intrusion. The smooth, non-wetting surface prevents the buildup of slime, sand contaminants, and bacteria, enhancing flow efficiency and discharge compared to traditional materials of equivalent size. This makes it the ideal choice for sewer systems, especially in the presence of iron ocher.
