Why use Precast Hollowcore?

Posted On: October 4, 2021

Precast Hollowcore slabs and flooring are an extremely popular and efficient construction element that is used within the manufacturing industry. This long term component with its long span creates less need for load bearing structures such as columns and inner walls.



Precast hollowcore slab’s span can be as long as 20 metres without intermediary supports, resulting in larger rooms with fewer partition walls. Non-load-bearing partition walls can be installed inside flats if long-span hollowcore slabs are used for the floor of residential buildings. This means, architects have more freedom due to the floor plan being easily changed.



Precast Hollowcore is often used for flooring across a range of designs and building types due to its versatility in spanning capabilities.

The hollowcore slabs have an extremely high durability as well as being extremely fire resistant making them perfect for today’s buildings. The slabs durability and reduced self weight also allows them to meet earthquake resistance standards. In addition, their great thermal properties help reducing energy consumption for heating and cooling of buildings.



Precast hollowcore slabs are not always used as horizontal structures. They can also be used as exterior walls, dividing walls, and noise barriers when put vertically. The large spans and long-lasting construction make this possible. Hence, they are especially beneficial for industrial buildings, where a high unified space is needed. The slabs, on the other hand, are highly resistant to changing weather conditions and effectively reduce noise, making them perfect noise barriers.



In general, hollow-core slabs are one of the most environmentally friendly building materials since they require less material – less cement, less water, and less steel – to manufacture than cast-in-situ slabs. In addition, the slabs’ voids make manufacture more material-efficient. As a result, the slabs are lighter, which lowers transportation costs because more slabs may be carried at once, as opposed to solid slabs. Because slabs won’t crack under service loads and all reinforcements are protected from corrosion, structures designed with hollowcore slabs have a longer life duration.
