World standard precast floor

Hollow-core slabs are prestressed floor elements with either round or shaped voids, depending on local conditions. They feature a range of advantages, among them long spans and excellent load bearing capacity. 

Using prestressed hollow-core slabs in buildings allows for large open areas as the need for partition walls is low. This results in unprecedented architectural freedom during and after construction.

The success of hollow-core slabs is due to highly efficient design and production methods, wide choice of unit depth and capacity as well as smooth underside and structural efficiency.

For the manufacture of prestressed hollow-core slabs, Elematic offers state-of-the-art extruder technology and slipformer technology, with the latter excellent also for other products

Less is more with hollow-core slabs

Prestressed hollow-core slabs are prestressed floor elements with either round or shaped voids, depending on local conditions. Featuring advantages such as longer spans and excellent load bearing capacities, our proven technologies for prestressed hollow-core slabs allow you to build large areas with less need for partition walls, resulting in unprecedented architectural freedom during and after construction. The success of our technologies is also due to highly efficient design and production methods, wide choice of unit depth and capacity as well as smooth underside and structural efficiency.

Ribbed slabs are most suitable for buildings where a lot of plumbing and holes are made in floor slabs.

Half slabs are most suitable for buildings where a lot of plumbing and holes are made in floor slabs. Half slabs are cast with wet concrete and usually have static reinforcement. The reinforcement consists of a mesh at the bottom and longitudinal truss girders, which provide good bonding with the topping and add strength prior to casting.
