The linings in the Aldol and Waste Caustic sumps had failed twice in three years due to elevated temperatures and aggressive chemicals.

Mobile’s crews removed all traces of old lining, sandblasted the surfaces, restored the surfaces to a smooth texture with a rapid cure mortar, then primed and installed glass-reinforced PolySpec 333 and 340 to meet the requirements of the chemical environment.

During the repair, ground water leaking into the sumps was stopped by pressure injection of a hydrophilic urethane resin, demonstrating Mobile’s ability to react to site conditions immediately and to complete the job on time and within budget.
