Stormwater Retention Tank Construction
R&K was part of the team that constructed a 3MG modular ground storage tank to aide one of its industrial customers control on-site stormwater flow.
R&K cleared a 2-acre site, performed mass grading, excavated/treated contaminated soils, placed crushed stone for an aggregate footing, for the 230’ X 310’ tank to be constructed on, and then assembled the tank. An existing sewer line was rerouted around the new structure, along with necessary stormwater piping.
Once the tank was assembled, the R&K team lined the inside of the tanks with geotextile liner and then monitored the tank while it was tested and put into use.
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.

BASF Corporation is the largest chemical producer worldwide. The project consisted of routing the new water header below and above ground around the perimeter of the 170 plus acre site. This header will service their plant operations for the foreseeable future. Being the general contractor of the project, R&K was also responsible for additional phases of the project, including concrete support structures, stainless steel pipe transitions, culvert installations, and more. R&K teamed with ISCO Industries and their certified fusion technicians to complete the pipe install.
