In potable water lines, epoxy is blown into cleaned pipes, forming a safe, evenly coated barrier between metal pipe walls and water. Epoxy lining is a permanent, preventative solution to leaks and breaks, blockages, prevents erosion, water damage and mold growth, and maintains water flow. The epoxy acts as a permanent barrier to heavy metals leaching in drinking water lines from metal piping systems.

Step 1: Pipe System Diagnosis

The project begins with mapping the internal plumbing system. A plan is implemented to minimize disruption and afford the most efficient timeline for work completion. The piping system is inspected for integrity and spot repairs are made to excessively worn joints and fittings. Temporary bypass water piping may be installed. The system is drained and air-dried. After testing for leaks, the pipes are prepared for cleaning.

Step 2: Pipe Cleaning

Pipes are dried with heated, compressed air. A safe abrading agent is blown through the pipe system, removing rust and corrosion by-products that are collected in a holding unit for disposal. Compressed air is applied once again to remove fine particles.

Step 3: Epoxy Lining

Optimal internal pipe surface temperature is created prior to epoxy coating. Another air pressure leak test is performed. Conditioned air is then introduced into the pipe to uniformly distribute the epoxy coating throughout the pipe segment. Following the coating application, continuous controlled air flows through the piping to facilitate epoxy curing.

Step 4: System Reassembly and Final Inspection

After the epoxy coating cures, valves and couplings are refitted. A final leak test and inspection confirms lining integrity. Water quality, volume, and flow tests confirm system functionality.
