Vaughn O’Dea, Technical Director at Epoxytec, authored a Tech Tip recently published by the National Association of Sewer Service Companies (NASSCO).

The article, Brick Surface Preparation for Brick Masonry Manholes, examines the challenges of rehabilitating brick masonry structures within collection systems. It emphasizes the importance of proper surface preparation to ensure the effectiveness and long-term performance of rehabilitation technologies.

Key Takeaways

• Why brick masonry manholes present specific challenges in rehabilitation
• How hydrogen sulfide corrosion impacts mortar while leaving brick largely intact
• The role of surface cleaning and preparation in achieving durable lining system performance

This article reflects Epoxytec’s ongoing work in defining best practices and sharing technical guidance with the industry—knowledge that is now also part of NASSCO’s revised Manhole Rehabilitation Performance Specification Guideline (PSG).
