How big can precast concrete panels be?

Panel size should be suited to the building design. For instance, for a single-story structure, the panel may be eight to 10-feet tall, and 20 or 30 feet long. For a two-story building, the panel might be 15- to 20-feet tall.

How is precast concrete measured?

Measure the distance between the landing that will connect with the top of the precast concrete steps and the ground vertically and compare your measurement with the height of the concrete steps. Adjust the ground height by digging deeper if the steps are taller or by adding dirt if it is shorter.

How wide are concrete slabs?
