Kingdom Koncrete, Inc. (Kingdom) is engaged in providing pre-mixed concrete into the Company's mobile mixer trailers, which are then towed by one of its customers to a job site of their choosing. Kingdom Concrete serves contractors and homeowners in North Texas with transit-mix trailers for small-pour concrete jobs. The Company sells concrete on small, manageable, mobile mixing trailers to help a smaller project. One trailer can mix from j to 1j yards for patios, sidewalks, slabs, fence posts or other concrete work.

The Company's operations consist principally of formulating, preparing and delivering ready-mixed concrete to the trailers at the Company's batch plant in Rockwall Texas.
