Ceiling hollow blocks

Concrete hollow blocks are used in RECTOBETON pre-stressed ceiling systems from RECTOR. The width of the hollow blocks is fixed, but they differ in height, which makes it possible to design ceilings with the thickness from 16 to 34 cm (including concrete topping). The hollow blocks are made of pure concrete with no fillers that could reduce their strength. Each pallet includes a specific number of sealed hollow blocks, which are arranged as edge hollow blocks. As there are no separating ribs in RECTOR systems, the hollow blocks are stacked along the entire length of the beam, without leaving any space for reinforced concrete ribs. Once laid, the hollow blocks form an even plane with the bottom of the beams, which is usually finished with gypsum or cement-lime plasters.
