1. Coatings & Lining for Underground Infrastructure

2. Most Commonly Forgotten Last to be Completed

3. Corrosion, Infiltration and Erosion are Quickly Deteriorating Underground Structures Corrosion from MIC Infiltration Erosion & Abrasion

6. How Do We Achieve Long Term Protection of Underground Infrastructure? 3 Select the Correct Product or System 3 Select Manufacturers That Provide a Full System 3 Adequate Thickness 3 Monolithic Protection 3 Adhesion to the Substrate

7. Talking Point: What Changes Have Taken Place Our Infrastructure in Recent Years? 3 Clean Water Act of 1987 3 I/I Elimination 3 Concrete Mixtures 3 Sewer Separation 3 Expansion New Construction 3 Coatings & Linings are Needed More Than Ever

8. 1. Selecting the Correct Product or System Understand the Chemistry Understand the Chemistry Was This Product or System Designed Specifically for the Environment? Was This Product or System Designed Specifically for the Environment? Is This Product or System Moisture Tolerant? Is This Product or System Moisture Tolerant? Is it Compliant to Third Party Industry Testing? Is it Compliant to Third Party Industry Testing? Is it Environmentally Friendly? Is it Environmentally Friendly?

9. 2. Full System Ensures Compatibility of Materials Limits Liability

10. 3. Goal: Thickness INDUSTRY RECOMMENDED THICKNESS New concrete: 80-100 mils Rehab concrete/masonry: 125+ mils STRUCTURAL REQUIREMENTS Generally, 125-500 mils for polymer only specs

11. 4. Monolithic Protection A barrier without fault Porosity Pinholing and Seam Welding Integrity Checks

12. 5. Adhesion Verifiably acceptable mechanical bond –Surface Preparation –Installation –Formulation – surface and moisture tolerant

13. Conclusion - How Do We Achieve Long Term Protection of Underground Infrastructure? 3 Select the Correct Product or System 3 Select Manufacturers That Provide a Full System 3 Adequate Thickness 3 Monolithic Protection 3 Adhesion to the Substrate
