Kraemer Mining & Materials

What Kraemer Mining & Materials does

Kraemer Mining & Materials, Inc. is a family-owned private aggregate producer headquartered in Burnsville, Minnesota, operating since 1959 the approximately 350-acre Burnsville Quarry — the single largest quarry in the Twin Cities metro by volume sold. The quarry produces 2.5 to 2.8 million tons per year of dolomitic limestone sold by the ton across a product portfolio of washed aggregates, base products (Class 5, Class 2, recycled crushed concrete and asphalt), industrial sand contract mining services, landscape rock (rip rap) and agricultural lime. Ancillary revenue comes from consulting in mine planning, drilling, permitting and environmental work, and from a 2009 water treatment partnership with the State of Minnesota and the cities of Burnsville and Savage that processes approximately 3 million gallons per day from quarry dewatering operations.

The business operates a sales-led, direct-distribution model: customers call a dispatch center (952-890-1361) for estimates and delivery coordination using a fleet of independent truck drivers serving the Twin Cities metro, while retail partners (Bachman's, Rock Hard Landscape Supply, Hedberg Supply, Plaisted Companies) reach smaller residential and landscape buyers. Customer mix spans municipal and state projects (MnDOT I-35W, cities of Burnsville and Savage), enterprise commercial work (MSP International Airport, Mall of America), mid-market institutional buyers (Lakeville South High School) and a long tail of metro-area contractors and homeowners. The 47-person operation holds the necessary Minnesota Pollution Control Agency and DNR permits, operates under direct MSHA oversight for engineered blasting, and has earned consecutive safety awards from Acuity Insurance (2014-2021) and a 2017 Platinum Safety Excellence Award from Aon. The quarry is directly adjacent to the Union Pacific Railroad, supporting long-term plans for rail-delivered aggregate supply alongside on-site ready-mix and asphalt plant tenants.
