PICOTE BRUSH COATING - PIPE REHABILITATION

Orsco offers a range of trenchless solutions to restore damaged pipes, tailored to address specific issues. All our pipe relining services begin with descaling, an essential preparation step for all trenchless methods, including Brush Coating.

Brush Coating involves applying a protective 100% solids epoxy resin to the interior walls of freshly descaled, structurally sound pipes. While coating serves as a non-structural repair, pipe patching and relining provide structural solutions.

APPLICATION PROCESS

Brush Coating involves applying a protective 100% solids epoxy resin to the interior walls of freshly descaled, structurally sound pipes. The coating is remotely pumped into the pipe and evenly dispersed using a spinning brush applicator. This process is visually monitored and inspected via video link to ensure precision.

Brush Coating:

  • Seals and fills cracks and voids up to 1/8 of an inch wide
  • Prevents the return of corrosion and scale
  • High tolerance to temperature and pressure
  • High resistance to chemicals and abrasives
  • Uses environmentally safe materials

This quick-setting process results in a restored and protected pipe, ensuring longevity and reliability.

Perfect Solution / Application for the following :
  • Small Diameter
  • Rust Inhibitor
  • High Temperatures
  • Multiple Reinstatements
  • Chemical Resistance
  • Pressure Pipes
  • Multiple Bends
  • Potable Water

WHAT MAKES US DIFFERENT 

We use Picote 100% Solids Epoxy Resin. Used to rehabilitate decayed and damaged concrete, pvc, fiberglass, clay, cast iron and ductile pipelines. The dual colour method allows for clear visual verification during application. Designed exclusively for the Picote Brush Coating™ System

NSF 61.5 Certified (white), ASTM certified, WRC Approved.

KEY BENEFITS 

This product is designed to renovate drains, sewers, water pipes, electrical conduits, HVAC ducts, and more through brush casting a specialized coating. The formulated resin creates a semi-structural, corrosion-resistant barrier inside the original pipe. It is a tested, safe, and environmentally friendly solution that makes the new pipe damp-proof, corrosion-resistant, wear-resistant, and non-corrosive. With its high breaking stretch, the new pipe can withstand shocks and bending, making it both elastic and antistatic.

  1. Extend the Lifespan of the Original Pipe:
    • The resin can significantly prolong the life of an existing pipe.
    • Thoroughly clean the pipe and apply single (0.5-1mm/coat) or dual coats of resin.
    • The new slick inner surface enhances flow, reducing the risk of blockages.
  1. Create a New Semi-Structural Pipe:
    • Apply multiple coats of resin to form a seamless new pipe with a 2-4mm wall thickness, depending on the diameter of the drain.
    • Designed for a 30-50 year lifespan when using Semi-Structural Design Specifications based on pipe diameter.
 

THE PICOTE SOLUTION

The Coating Pump delivers resin to the interior of the pipe, while the rotating Mini Miller shaft turns brushes that spread the resin evenly over the inner pipe wall. The process begins at the pipe’s farthest end from the access point. Resin is pumped into the pipe and brushed onto the wall. The coating is then inspected by retracting the brushes to the starting point and using a camera for verification. This procedure is repeated along the entire length of the pipe until the brush assembly reaches the access point. Subsequent layers can be applied at intervals of two to four hours, or less than one hour if hot air is used to accelerate the curing process. Multiple coats are recommended based on the pipe diameter and intended application.

Applications include:

  • Storm Water Lines
  • Sewer Lines
  • Down Pipes
  • Cast Iron Pipes

ATTENTION END USERS:

We are increasingly encountering unqualified service providers using incorrect products in pipelines, which often leads to further damage.
