What Do you Get When High Performance Coatings and Quality Craftsmanship Meet to Take on Settling Basins?

By: Paul Powers, Induron North Central Regional Manager

Back in 2018, Induron teamed up with Texarkana Water Utilities (TWU) to develop specifications for several of their uncoated aging settling basins, which were in critical need of refurbishment. After several discussions, reviewing the condition of the basins, and working within the regulations unique to the region, the specifications for refurbishing the settling basins were ready to go. 

The coating solution

Like many utilities, TWU originally considered membrane urethane systems. However, when they learned that Induron’ s Perma-Clean 100 Ceramic NSF 61/600 Approved Epoxy’s approval is up to 150 Mils, which was the same thickness as the membranes they reviewed initially, they changed their minds. We showed TWU the test data on the flexibility of this ceramic-pigmented product, which is unmatched by other epoxies. All in all, Perma-Clean 100 was an excellent choice for this project because it provided the protection of an epoxy with more flexibility than even needed for this concrete project.

Perma-Clean 100 is a fast-curing, 100% solids epoxy tank lining for potable water applications. It provides enhanced edge retention, which improves corrosion protection on corners and sharp angles. Competitive products are not enhanced with ceramic pigment into an amine-cured epoxy resin for maximum corrosion protection of immersed substrates and can take up to 7 days or longer to cure for full immersion service. Formulated specifically for protecting steel and concrete for potable water immersion, Perma-Clean 100 becomes dry to walk on in 10 hours at 70F, which allows for quicker inspection times, and can be placed into immersion service in 72 hours at 60F and above.


The project team

For this refurbishing project, I recommended the contractors, worked with each of them on all three basins, and provided pricing and technical support. One contractor partner completed the refurbishment of the first basin, and another trusted partner, Thomas Industrial Coatings located out of the St. Louis Metro Area, completed the other two basins. 

I have had the privilege of working with Don Thomas, the owner of Thomas Industrial Coatings, and his team even before he launched his company back in 1991. Since then, I have worked on a wide range of diverse projects with their team. My trust in their abilities and dedication to their craft was why I opted to  bring to the table on TWU’s behalf and one of the reasons that they have grown to be the company that they are today. Partnering with contractors that share the “do it right the first time” mentality is key to a successful project, and that these guys did not disappoint! 

Our third partner in these projects, the owners (TWU), could not be more pleased with the performance, craftsmanship and value that these projects delivered. Another large-scale concrete project case history complete!
