Ergon has a range of floor and roof slabs, composed of SP-slabs, TTP-slabs and TTD-roof slabs, that allow the optimal use of prefabricated prestressed concrete.

The most important advantages are:

• execution speed as well in manufacturing as in erecting;
• flexibility in design: choice of span, infinite combination possibilities with all kinds of material for floor or ceiling finish;
• light and very thin floor constructions;
• long spans require less columns and sagging beams, allowing to span the external walls in one go;
• sometimes a compression slab is no longer needed.

Floor slabs have several functions:

• support vertical loads;
• load distribution of point or linear loads through the joints;
• transfer of horizontal forces to the rigid elements of the supporting structure through diaphragm action;
• support of large horizontal forces due to water or soil pressure when building underground constructions.

Range of application

SP-floor slabs are successfully used in:

• office and school building
• light industrial loads
• car parks
• many other applications

TTD-roof slabs are developed as a light roof slab with a large span (up to 12 m). They are used in the same range as the SP-floors slabs and also in:

• hospital
• heavy industrial loads
