Armen Cleaners
Conducted insitu- chemical soil stabilization for VOC contaminants. Taplin was identified to conduct soil stabilization at the Former Armen Dry Cleaners site in Ann Arbor, MI. The project site was broken up into grid patterns and columns; with a total of 18 grids and each grid having 9 columns each.
A Komatsu PC490 excavator was outfitted with an ALLU rotary/mixing head connected to the ALLU pressure cart via large diameter air hoses. The ALLU pressure cart has two large separate dry vessels that was filled with Sodium Persulfate and Portland cement that was controlled by high-volume high-pressure air. The excavator with ALLU head would rotary down into the columns to loosen the soil for the initial pass. The excavator with ALLU head would then rotary down in as a second pass injecting 2,500lbs of the sodium persulfate that was being transferred from the pressure vessel. The third and final pass of the ALLU rotary head was the 1,500lbs Portland Cement. Water was introduced during all three passes to keep the soil and amendments from tightening up during the process. A total of 390,000lbs of Sodium Persulfate and 380tons of Portland Cement was used to complete the project.
