• What is the difference between tiltwall construction, tilt-up panel construction and pre-cast concrete construction? Tilt-up panel construction process consist of putting a large slab of concrete (panel) directly at the job site. Tiltwall construction consists on the same process, but the size of tiltwall panels is limited only by the needs of the building and the strength of the concrete panels themselves. Tilt-up construction offers more flexibility.
