1. Pipe Relining Technology Brought to you by: DATTATREYA INC. Where life interacts with infrastructure.

2. COMPANY OVERVIEW Technologies:  Patented epoxy and coating process – REDLINE  Patented Structural Lining processes, including CIPP and PIP, and small-diameter relining – BLUELINE  Patented Structural Lining for high pressure water mains – GREENLINE More than 500 licensees or applicators including installers throughout North America, Europe, Asia, Australia and Africa Patents: 21 Combined annual turn-over for REDLINE is over 100 million USD.

3. Epoxy Coating (Blown-in technology) Structural Liner (Pull In-Place Technology) TECHNOLOGY

4. REDLINE TECHNOLOGY Pipe Renewal and Coating Process 1.Pipe layout & Inspect pipes to learn about their condition 2.Clean pipes using our pneumatic tools and dried using hot air. 3.Apply blown-in epoxy coating using clean air from smallest to largest pipe 4.Epoxy barrier cures

5. Pipe Cleaning Process 1. Dried using warm air. 2. Cleaned starting at the largest pipe to the smallest pipe (Overlapping Process) 3. Garnet introduced in the air stream and sands pipe clean. 4. Discharge point is connected with filter to collect particles REDLINE TECHNOLOGY

6. Sand used for Blasting Cleaned Pipe REDLINE TECHNOLOGY

7. Problems Addressed Pinhole leaks Mineral deposits, which limit water flow Rusty water/discolored water Corrosion build-up, which can limit flow for HVAC systems and plug up sprinkler heads for fire suppression systems Fitting and joint leaks REDLINE TECHNOLOGY

8. Advantages Safe and Durable Cost Effective Minimal Downtime Minimal Disruption and No Occupant Displacement Quick, quiet, non-invasive Versatility in Applications (12 -300mm) REDLINE TECHNOLOGY

10. BLUELINE TECHNOLOGY Pipe Lining Procedure Camera Inspection to locate cause of failures and identify locations Clean pipes using our pneumatic tools and dry using hot air. Installation using existing access points Post Camera Inspection

11. Problems Addressed Cracks and holes in pipes that become brittle from corrosion Missing bottoms from heavy, corrosive waste Debris build-up and obstruction causes limited flow and back-ups Root intrusion in underground pipe lines causes back-ups BLUELINE TECHNOLOGY

12. Advantages No-Dig Installation custom built on-site Versatile Application ( 40mm- 1000mm) Access pipes which generally can’t be accessed BLUELINE TECHNOLOGY

13. REDLINE Hot and Cold Potable Water Systems Potable Water Risers Compressed Air HVAC / Hydronic and Chiller Systems Fire Suppression Systems Processed Piping Conduit Piping Chemical Piping BLUELINE Vertical Sanitary Stacks Horizontal Sewer Branches Sewer Lines Roof Drain Systems Spot Repair Liners Storm water APPLICATIONS
