A concrete slab is usually reffered as a common structural element of buildings. But with blockanddrip it is much more than just that, it reinforces the building that is being worked on with specifications made specificly for the project at hand. That is why it is so important to choose the correct concrete slab and we got you covered when it comes down to that.
We provide concrete slabs that is suitable for any climate zone and longevity.
This is the most common type of concrete slab. They can be conventional slabs with deep excavated beams insulated beneath floor panels or waffle pod slabs that sit at near ground level with a grid of foam pods.
These slabs are constructed above ground level. They are commonly used for floors of upper stories as they have a removable and non-load bearing framework.
These are slabs manufactured offsite and put into place with a crane. They can either come in their finished form or require only an additional thin layer of concrete after installation.
Thermal mass is the ability of a material to regulate thermal energy. Materials like concrete slabs have high thermal mass. They regulate indoor comfort and provide a heating or cooling effect for humans by radiating or absorbing natural heat. The property of temperature regulation is useful in most climates and in areas with a high day and night temperature range. Thermal mass is most effective when used in conjunction with good design layout.
During the winter, slabs should be designed to absorb heat from the sun and other sources of energy. Thermal mass involves the storage of heat and allows the steady release and re-radiation of it later on. On the other hand, slabs should be protected from direct sunlight in the summer. They need exposure to cool breezes in the night so heat overflow during the day can dissipate.
A concrete slab can have a prolonged life span with proper reinforcement. This means concrete should be compacted so there are no voids or porous areas within the slab, reducing the risk of concrete cracking.
Concrete slab longevity can be promoted with proper foundation preparation and the addition of an appropriate amount of water. An excess of water will cause the concrete to crack and weaken the overall slab. Concrete installation should also adhere to construction timelines so concrete reaches designed strength level before any load is placed.
Slabs should be designed and constructed in accordance with proper Australian Standards. Concrete treatments can be provided to the slab’s joints, penetrations, and edges. This ensures minimum termite risk and allows for limited shrinkage or cracking.
Reactive soil sites require floating stiffened concrete raft slabs that use void formers at regular intervals. Reinforced beams for concrete are closely spaced and have a crisscrossed design around the bottom of the slab.
Steep sites are those with geotechnical specifications that render slab-on ground concrete installation impractical. The suspended slab concrete type is more suitable for a structure to gain thermal mass on a steep site.
Buildings with concrete slabs that follow design requirements and adhere to construction standards can provide thermal and longevity benefits to improve overall energy and cost-efficiency.
