Concrete Silos Preserved
TMI Coatings completes a job safety analysis prior to beginning work. Upon safely rigging or accessing the silos TMI prepares the surfaces by water blast cleaning to remove loose and flaking old coatings and to expose concrete areas requiring repair. Inferior concrete is removed exposing rebar. Rebar is cleaned, abraded and primed to reduce further rusting which can be the cause of spalled concrete.
After surface preparation work is complete, TMI Coatings applies a primer/sealer coat to the concrete silos. After the primer is applied, TMI applies an elastomeric coating to the silos. Elastomeric coatings are waterproof and resist wind-driven rain due to their flexibility. Large projects specified with an elastomeric coating come with a 5 year labor and material warranty guaranteeing the coating will not chip, peel or flake.
TMI also coats silo and head house roofs. After removing the existing roofing by pressure washing, scraping, grinding and/or sandblasting, TMI repairs splits, blisters and punctures on the roof. The next step is applying an asphalt-based urethane elastomer roofing system. Applying this in a heavy-duty, thick film manner provides a seamless, monolithic membrane. Aggregate incorporated into the roofing system provides slip resistance.
These steel bolted silos were allowing moisture intrusion due to the pressure of the product and mother nature creating small voids in the flanges of the panels. TMI applied a urethane elastomer seam sealing product to the bolt heads and ends and the flanges of the panels to create a watertight seal prior to applying the exterior coating system.
