What is Hollowcore Concrete flooring?
Hollow core slabs are precast, prestressed concrete elements that are generally used for flooring. Some of there advantages are as follows:
- Long spans, no propping
- Flexible in design
- Fast construction
- Light weight structures
- Fire Resistant
- High load capacities
- Manufacture unique units specifically for your project
What is Prestressed concrete?
Prestressed concrete is a combination of high strength concrete and tensioned steel strands. This combination makes a very strong structural material that is used in the building of roof slabs, bridge girders and railroad ties. Prestressed concrete was invented and patented in 1886 by Henry Jackson, a San Francisco engineer. This type of concrete became the material of choice in Europe after World War II, due to the shortage of steel. The Walnut Lane Memorial Bridge, built in 1951 in Philadelphia, Pennsylvania, became the first structure in America made of this type of material.
Why use Block and Beam flooring?
Block and Beam floors provide a quick and economical solution for most structural flooring situations, both at ground and upper floor levels. This type of flooring is also suitable for refurbishment contracts or sites with restricted access, where easily handled components are required.
What is reinforced concrete?
Reinforced concrete is manufactured from a combination of high strength concrete and normal reinforcement bars.
What is the maximum span of hollowcore floors?
The maximum span of hollowcore floors will depend on the floor depth and the specific loadings imposed on the floor. Our technical department will be able to advise you on the most economic unit for your specific condition.
Can you build solid walls on precast concrete floors?
Yes we can generally design the floors to carry solid walls. If you advise our sales personnel of your requirements at the enquiry stage you will be given the range of unit depths required for the various wall load options.
Do foundations need to be changed to carry precast concrete floors?
Normally standard foundations will be capable of dealing with the additional loads from the concrete floors in a domestic situation. Further advice should be requested in piled foundations or in multi storey situations.
