About 50% of the residents live onsite year around. It was not just about lining or coating the pipes, the contractor had to shut down fixtures sharing common piping. In the case of an in-building renovation of such a large scope with over 26,000’ (7,950m) of trenchless rehabilitation, project planning and communication with the tenants/owners was critical.

All pipes were thoroughly cleaned with Picote Millers and tooling, then rehabilitated with either CIPP liners or coated with the Picote Brush Coating™ DC1000E resin, often in overlapping processes to complement each other.

The Picote Brush Coating™ system featuring the Mini and Maxi Coating Pumps and DC1000E resin was used on this project. The coating process applies a specially formulated 100% Solids Epoxy Resin which is pumped through a delivery hose and applied to the walls of the pipe via rotating brushes attached to a Picote Miller Shaft. The extremely flexible Picote Miller shafts made navigation of the multiple bends easy, even inside the very small 2” (DN50) pipes in this project.

Jason Lohoff, Owner/CEO of Master Rooter stated: “Using Picote in conjunction with CIPP on many projects gives customers a non-invasive way of still rehabilitating their drain lines where either traditional CIPP will not work, or we can use Picote in conjunction with traditional CIPP.”
