On the typical concrete pour, your goal is to place the concrete as close as possible to its final destination—not only to save hauling time and boost productivity, but also to avoid overhandling the concrete. But on many concrete jobs, the ready-mix truck can't gain access to the work site. When you're placing a stamped concrete patio in a fenced backyard, a decorative floor inside in an enclosed building or working on a high-rise building, you must find another way to move the concrete from the truck to the point of placement. Pumping is an efficient, reliable and economical means of placing concrete, and sometimes the only way of getting concrete into certain locations. Other times, simply the ease and speed of pumping concrete make it the most economical method of concrete placement.
