Consists of a special corrugated cardboard box, wax coated on the outside to withstand temporary moisture of concrete when casting. Depending on the slab thickness special stiffeners are placed inside Void Formers. In contact with moisture or water the JOLUKA VOID FORMERS slowly disintegrate leaving a Void for soil movement.  Advantages: \u2022 Light weight. \u2022 Easy to position. \u2022 Saves up to 50% of time. \u2022 Cost effective compared to conventional methods. \u2022 Can be used for beams, slabs, flat surfaces, etc. \u2022 Different sizes, thicknesses and shapes can be manufactured as per engineers' specifications."}
