Walls

Precast concrete wall slabs mostly are used in the structures of multi-storey residential houses, hotels or other similar structures. Load bearing walls are used in combination with floor slabs of hollow core slabs. Also they are used for partitioning structures and lift and stairway wells. The greater dimensions of wall elements, the more economical is the project, and the greater is construction productivity. Lifting facility and transport facility capacities can influence restrictions in wall production.

Precast concrete walls are manufactured in the stand-type or battery-type moulds. The mould-side surfaces of production items are smooth, while the top surfaces are levelled and trowelled.  Prior to painting or wallpapering, a minimal conditioning of surfaces is necessary. Service ducts or embedded parts are installed when moulding a production item.

There are two types of wall slabs: three-layer and two-layer slabs. Mostly slabs are of one storey height, while the widths of the structure will be designed to the wish of the customer.
