Hollowcore Slabs

Pre-stressed hollow core slabs are the most widely used type of precast concrete flooring system due to their highly efficient design and production methods, as well as their available range of depth and capacity. Hollow core slabs are primarily used horizontally as floor, roof deck systems and, bridge deck units; and can also be used vertically as wall panels and boundary wall panels. The continuous voids, or cores, in the hollow core slabs provide a reduced weight and thermal and acoustic characteristics.
Hitech manufactures different thicknesses of hollow core slabs ranging from 150mm up to 500mm thick. Hitech is one of the very few companies that provide hollow core slabs with widths up to 1200mm and 2400mm. Slabs with narrower widths can be provided based on design requirements. Depending on the load conditions, slabs with relatively long spans can be designed, produced, and erected on site. Hitech’s hollow core production facility is equipped with the latest American (Spancrete) and European (Elematic) computerized casting equipment and machinery including multi-stressing devices, diamond cutting saws, and automated batching plant.
Openings and holes can be formed in hollow core slabs within the limitations imposed due to slab thickness, span, loading, location of strands, core size, and position. Small holes are usually made, by rotary drill, at the site after erecting the slabs. Fastenings to hollow core slabs is easily achieved and various methods are suitable.
