Prestressed Hollow Core Slabs
PPS — Fast & Safe
Prefabricated structural elements enabling economical, fast and safe construction of floor structures for all types of buildings.

Low weight
PPS weight is 37–54% less than standard solid slabs — direct savings in foundations and structure.
Large spans
Prestressed slabs can bridge spans of up to 19 metres without load-bearing walls or columns.
Fast assembly
Standardised dimensions and a simple installation system reduce construction deadlines by 50% or more.
Green construction
Using equal amounts of material, labour and energy, 1 m² of conventional slabs or 2.5 m² of PPS are produced.
Fire resistance
All types of PPS slabs are certified for fire resistance REI 60 minutes according to EU standards.
System adaptable
Applicable in reinforced concrete and steel load-bearing structures — without modifications and without on-site finishing.
Thicknesses 20–50 cm, spans up to 19 m
The slabs are one-dimensional prestressed elements of constant cross-section. Standard width is 120 cm. They are delivered in the required lengths, with a protective concrete cover of min. 25 mm.
- Thicknesses: 20; 26.5; 30; 35; 40; 45; 50 cm
- Live loads from 2 to 20 kN/m²
- Fire resistance REI 60 minutes
- Standard slab width: 120 cm
