What Are Suspended Concrete Slabs?

Concrete slabs are often used in building projects due to their practical benefits. They are commonly used to construct floors, ceilings, and roof decks in modern buildings and even some domestic properties.

If you’ve been looking for a versatile building material, concrete slabs might be suitable for you.

These slabs come in various forms including slab-on-ground, precast slab, and suspended slab.

In this blog, we’re going to focus on the qualities and benefits of suspended concrete slabs in particular. We’ll also talk about how concrete slabs are made and how they’re installed and maintained.

Production and Installation of Suspended Concrete Slabs

• Composition and production

A concrete slab is a flat, four-sided horizontal surface that is typically reinforced with steel for added strength and stability. The concrete is made up of stone aggregate, sand and cement. When you mix these materials in water, it creates a chemical reaction causing the mixture to solidify.

It’s important to note that this process usually consumes a lot of energy and emits significant amounts of carbon dioxide.

That being said, there are plenty of ways to reduce the environmental impact of concrete production. This includes using cement extenders and recycled aggregates.

• Installation

Suspended concrete slabs are formed in situ, meaning they are poured at the actual project site. The concrete mix can either be poured into removable or permanent formwork.

As the name suggests, suspended slabs are concrete slabs that do not make contact with the ground. They are often used for ceilings, roofs or floors that are above ground level.

They can be supported on two sides or on all four sides via columns and/or beams. Slabs that are supported on two sides are called one-way slabs. This is because slabs that are supported on two opposite sides bends in one direction only. On the other hand, when a slab is supported on all four sides, it will bend in two directions. Hence, two-way slab.

Benefits of Suspended Concrete Slabs

• Reduced energy consumption

Concrete slabs offer thermal mass. High thermal mass materials have the ability to absorb, store and release heat. This means slabs can minimise temperature fluctuations and allow the building’s interior to remain warm during the winter months. Thermal mass is also advantageous in areas that experience extreme temperature changes between day and night.

Insulation material can also be added underneath and on the edges of the slabs. However, to preserve the effects of thermal mass, the top surface of the slab shouldn’t be covered by materials like carpets or rugs.

Reduced temperature fluctuations and added insulation can help you save a lot of money on heating and cooling costs.

• Safety and durability

It is said that reinforced concrete slabs can last anywhere between 50 to 100 years. Because of this, you can rest easy knowing that the structural integrity of your property will remain intact for decades to come.

Concrete slabs are also fire-proof. This can be beneficial if your area is prone to bushfires or other types of fire hazards

Despite this, it’s still important to take the necessary precautions to ensure the longevity of concrete slabs. For the slabs to last as long as possible, there are a number of things that you need to consider. This includes adding the right amount of water in the mixture, preparing the foundation properly, allowing the concrete to cure completely, applying termite protection and so on.

Since there’s a lot that goes into maintenance and production, it’s best that you work with a reputable builder when dealing concrete slabs.

• More space

The space underneath suspended concrete slabs is perfect for storage. This space can be used to store laundry items, bulky appliances, housekeeping equipment and other household items that aren’t used very often. In turn, this can save a lot of space in other parts of your property. If the slabs are used for ceilings, you can maximise the vertical space of your interior.

If you’re considering suspended concrete slabs for your next building project, consult your local concrete contractors. For the sake of your own safety and financial well-being, we recommend looking for an experienced and reputable team of professionals.
