Interlock Paving Company began manufacturing high-quality interlocking paving products in LeSueur, Minnesota in 1985. A wide variety of precast concrete landscape products were added to the product line in 1993 by teaming up with Barkman Concrete headquartered in Winnipeg, Manitoba. To better emphasize the expanded product offering, the company then changed its name to Interlock Concrete Products. Construction of our current state-of-the-art production facility began in 1995 in the beautiful Minnesota River Valley outside of Jordan, MN. Here, we manufacture a wide selection of well-known paving and retaining wall products for residential and commercial use.
