Our 301-QI Quick Invert epoxy blend allows us to eliminate inflow and infiltration while making immediate return to service of manholes possible.

Lining the invert channel is an essential part of the manhole rehabilitation process as infiltration often occurs below the flow line. Unfortunately, it’s a commonly skipped step due to the difficulty and extended downtime. Our 301-QI epoxy makes it possible to coat the invert at the start of the project and immediately return the manhole to service upon completion of the epoxy lining.

The Advantage

Barrier Coating

Our epoxies protect substrates from corrosives, microbial attack, abrasives, sewer gases, and more, making them an ideal solution to protect and extend the life expectancy of a broad range of assets.

Structural icon


Our epoxies enhance the physical condition of the host structure, allowing us to quickly restore its structural capacity. One coat can add over 75 years to infrastructure without the disruption to vital operations.  

Single coat icon

Single Coat

We are the only company whose epoxy can be spray applied in one coat up to 500 mils (½-inch thick). This minimizes immediate downtime and disruption, allowing for a rapid return to service. It also eliminates the risk of delamination associated with all our competitors’ multi-layer systems.

Extends lifespan icon

Adds +75 Years

In one coat, our structural epoxies can add over 75 years of service life to your infrastructure (independent study conducted by the University of Pittsburgh).

Superior Adhesion icon

Superior Adhesion

Our epoxies are exceptional in their ability to adhere to concrete, brick, steel, iron, and nearly every substrate even under damp, wet or humid conditions.

Zero VOCs

All our epoxies are non-hazardous. They are free of VOCs, solvents, styrene, and isocyanates – this eliminates the risk of explosion, fire, and extreme health issues for workers and surrounding areas.

Since 1996

Proven Since 1996

We invented the first application system capable of spraying 100% solid epoxy, with no harmful solvents or thinners. Our oldest installations from the early 1990s are still in service and still in excellent condition today.
