Smooth, level floors for shops, warehouses, pole barns, and garages — poured and finished year-round, even in winter.
Diaz Concrete pours and finishes interior concrete floors across the Siouxland area — shop floors, pole barn and machine shed floors, warehouse slabs, garage and basement floors. Because the work is indoors, we can schedule it any time of year, including the winter months when outdoor concrete has to wait.
Free on-site estimates. Serving Sioux City, IA, and the surrounding tri-state area including Nebraska and South Dakota.
Indoor pours are not held up by snow or frozen ground. Get your floor done this winter instead of waiting until spring.
