The in-place pipe restoration process is an economical and efficient alternative to traditional pipe system replacement.

Our proprietary technology allows us to restore aged, corroded piping systems in-place to a “better than new” condition without the use of chemicals or mechanical devices. The epoxy coating applied to the pipes’ interior, seal and protects the system from further deterioration and dramatically extends system life. The process can be used on a variety of pipe material including galvanized steel, cast/black iron, copper and lead.


The Lowery trenchless pipe repair process is a Nu Flow patented process that uses heated conditioned air to move a non-toxic abrading agent through designated pipe runs and segments. The movement of the agent through the pipe dislodges the corrosion buildup and transports it to an exit opening in the pipe where it is collected in a cyclonic grit unit and secondary dust collection system. The waste corrosion product is non-toxic and easily disposed of without any harm to the environment.

The result is a clean, rust-free polished surface inside the pipe. Following pipe cleaning, a potable water safe, NSF61- certified* liquid epoxy is distributed through the piping using heated controlled air flow to facilitate optimal adhesion and curing. The coating will cure within 12-24 hours, after which time the system is re-assembled and returned to service next day. The result is a smooth and durable finish resistant to further corrosion and deterioration.
