Voided Slab System

Voided Slab Formwork System

A reinforced concrete slab solution made from recycled plastics that enables large-span slabs to be easily passed without beams, creating voids within the slab to provide up to 25% cost savings in concrete and steel in building costs.

Voided slab formwork systems are designed to remain in the concrete, forming layers above and below the formwork. Thanks to this innovative approach, a rigid lattice or grid structure is created with flat plates on the top and bottom, created with only one concrete pour. This method results in a significant reduction in the amount of concrete and steel used, making it an economical and environmentally friendly option for construction.

The voided slab system is an excellent solution for creating large-span plates or plates that can carry large loads without using beams. Thanks to its lightweight design and modular structure, it can be applied quickly and easily. This structure provides designers with complete architectural freedom, allowing them to change static and geometric parameters as desired.

Installation

1

Formwork Preparation

First, the formwork into which the concrete will be poured is prepared and its supports are placed. The surface of the formwork is covered with wooden floors, making it ready for concrete pouring. Bottom reinforcement bars are placed in two vertical directions according to the design and a cage is prepared for top reinforcement.

2

Voided Slab Formwork

For voided slab, the beam width is adjusted according to the specified dimensions in the static project. Thanks to the conical feet under the formwork, the voided slab formworks are raised from the surface to create the lower slab. If double or triple elements are used, these elements are assembled first.

3

Reinforcement Arrangement

Together with the top bars, the positioning of the reinforcement according to the design is completed, including shear and punching reinforcements.

4

Concrete Pouring

To prevent the surfaces of the formworks from floating, the pouring is carried out in two stages. First, an initial layer is poured as high as the conical foot height. This layer continues to be poured until the concrete hardens and becomes semi-fluid.

5

Continuation of Pouring

After the concrete pouring is adjusted appropriately, the pouring is restarted to completely cover the voided slab system. Then, the pouring is leveled in the traditional way.
