Waste Dump Expansion
R&K was contracted by Mississippi Lime Company in Ste. Genevieve, MO to expand their surface waste dump operation. The project entailed mass earthwork including construction of a 20 ft. berm and a clay cap of their existing surface dump. Over 100,000 yards of dirt were hauled and placed. Additional scope of work included: Clearing & Grubbing, Culvert Pipe Extension, Seed & Straw.
Sweetwater Dam Expansion
R&K was contracted to expand a tailings dam for the Sweetwater Mine. The Sweetwater Mine is located outside of Ellington, MO and has been in operation for more than 50 years as part of the Southeast Missouri (SEMO) Lead District. The project consisted of moving 560,000+ CY of material and raising the existing 3,000’ tailings dam by over 20 ft. The impoundment serves as the primary dam embankment for the mine’s 600-acre tailings pond. R&K’s survey and design team worked continually with the owner’s representative making value-engineering proposals and changes to the original design.
