Precast concrete shear wall panels provide a lateral load-resisting system when combined with the diaphragm action of the floor construction. The effectiveness of precast concrete shear walls is largely dependent on the panel-to-panel connections. In some cases, precast panels are used as formwork for cast-in-place concrete.

The greatest advantage provided by this support can also lead to its downfall as sometimes the structure requires a little deflection or some play to protect the surrounding materials. For example, as concrete continues to gain strength, it also expands. Hence it's crucial that the support is designed correctly else the expansion could lead to reduction in durability.
