Outdoor Building Landscape


This customer asked for 50' x 100' apron. This project has keyway doweled edges and rebar is 2' o.c. A 1' packed gravel based is hidden beneath the concrete to ensure a stable slab. It was poured in sections and cut accordingly for expansion.


Large Ag


This was an 80' x 120' heated shop floor with rebar 16" o.c. and 8" thick to provide extra strength designed for loaded semi trucks. A smooth power trowel finish for easy sweeping and two 20' and two 30' trough drains and a 40' oil pit.
