In 2018, Induron teamed with Texarkana Water Utilities (TWU) to develop specifications for their uncoated, aging settling basins. The basins were in critical need of refurbishment. After several inspections to assess the condition of the basins, and working within the regulations unique to the region, specifications were written for the rehabilitation of the structures.
The coating solution
Initially, TWU considered utilizing urethane membrane systems for this project. It was thought that these were the only systems available that would provide the needed thickness required to overcome the existing deterioration present in the basins. Induron was given an opportunity to present our NSF 61/600 Approved Perma-Clean 100 Ceramic Epoxy. Perma-Clean 100, having NSF approval of up to 150 mils dry film thickness, provided an alternative that was equally capable of overcoming such surface imperfections. We were able to demonstrate, through testing and previous applications, that Perma-Clean 100 provided the necessary flexibility required for a concrete project such as theirs. This, combined with the superior corrosion protection provided by a ceramic-pigmented epoxy proved to be an ideal solution to protect these assets.
Perma-Clean 100 is a fast-curing, 100% solids epoxy vessel lining for potable water applications. This ceramic-pigmented epoxy provides enhanced edge retention, minimal undercutting and a highly impermeable film that is ideal for immersion applications. Traditional solvent borne epoxy products can take up to 7 days or longer to cure for full immersion service, especially for these required film thicknesses. Formulated specifically for protecting steel and concrete for potable water immersion, Perma-Clean 100 typically is hard enough to walk on within 10 hours of application, which allows for quicker inspection times, and can be placed into immersion service in 72 hours.
The project team
For the execution of this project, Induron worked closely with the engineers, contractors and inspectors tasked with making this a successful job, providing technical support before, during and throughout the completion of the application.Induron recommended the contractor, Thomas Industrial Coatings, located out of the St. Louis Metro Area, a trusted and well respected applicator in the industrial coatings market.
Our trust in their abilities and dedication to their craft was why we opted to bring them to the table on TWU’s behalf, and one of the reasons that they have grown to be one of the most competent companies in the industry. Partnering with contractors that share the “do it right the first time” mentality is the key to a successful project, and they were able to execute the job in a professional and efficient manner.
There was a total of 3 large basins completed during this project. The applicators were complimentary of the user friendliness of the product. The owners were satisfied with the efficient manner in which the project was completed and pleased with overall appearance of the basins.
