Beginning on June 14, 2022, rehabilitation of approximately 494 vertical feet of existing manholes took place in various locations throughout the City of Pine Bluff. Midwest Infrastructure Coatings crews from Kimberling City, MO, were in town through October 10, 2022, to complete the project. Four foot diameter manholes ranging from 3' - 17' in depth were treated with Obic coating products to eliminate infiltration from entering the manholes. The process is a three part process in which the existing structure is cleaned & primed, coated with a foam application to seal cracks and crevices, and final polyurethane top coat, yielding a final product that is flexible and durable for years to come. The finished product comes with a 10-year warranty that is date stamped in each individual manhole.
