The reduction in weight offers benefits such as lower transportation costs and saves on the cost of materials required concrete.
Precast floor slab self weight.
Hollowcore slabs are typically used in the construction of upper floors in apartments and flats commercial buildings and larger houses.
In addition the panels have continuous voids in them that reduce weight and cost and also may be utilized for electrical or mechanical runs.
Hollowcore flooring is a precast prestressed concrete slab with tubular voids which run through the full length of the slab thereby reducing the weight of the unit.
Precast flooring federation part of british precast.
Precast concrete popularity is linked with low seismic zones and more economical constructions because of fast building assembly lower self weight less material etc.
Hollowcore planks can be attached to cmu walls steel beams or precast walls beams.
A hollowcore floor slab is a prestressed precast concrete element incorporating continuous voids to reduce self weight whilst providing an efficient structural section manufactured by slipform extrusion or wetcast.
This helps keep the construction process on track and adds another layer of efficiency to the project.
With the benefit of prestressing and low self weight longer spans can be achieved for the same loads or greater loads for the same depths.
