An apparatus, and a method of use of the apparatus, for forming a concrete slab are provided. A formwork may include a support element having a layer of active material bonded on each side to a backing sheet. The active material is chosen to slowly compress over time when placed under a load, and the rate of compression is chosen such that the layer of active material continues to support the slab until such time as the slab becomes self-supporting (i.e., the concrete has cured/set). Another feature is the inclusion of a surface of the backing sheet with a relatively low coefficient of friction. When two support elements are laid one on top of the other with the surfaces in contact, the upper support element may slide over the lower support element, for example during a seismic event.
