Manhole protection and rehabilitation has traditionally included either cementitious liners (particularly calcium aluminate and pure fused calcium aluminate) or epoxies for severe conditions resulting from H2S. These options have forced owners to either spend more money on costly, complex, specialized epoxy systems to improve performance or settle for the sporadic performance of the less expensive cementitious liners.

Fortunately a new option has emerged, hybrid epoxies are quickly becoming the prominent solution for manhole rehabilitation and protection because they combine the ease of application and economics of a cementitious liner with the performance of a high-build epoxy liner.

This webinar is designed to:

  • Explore the properties that make a liner suitable in wastewater environments
  • Understand the characteristics of hybrid epoxies
  • Compare hybrid epoxies to calcium aluminate, pure infused calcium aluminate, and traditional epoxies
  • Recognize beneficial application methods of hybrid epoxies
