28 Oct What are The Benefits of Concrete Suspended Slabs and Raft Slab?
It is a well-known fact that most single- and double-story structures use a lot of concrete as a foundation. But what many first-timers who engage in the double-story home building process don’t know is that having concrete suspended slabs is an excellent idea as well. Many building contractors use suspended concrete slabs between floors when constructing storied buildings.
However, some storied buildings also make use of raft slabs as foundations for both extensions and new houses.
Raft Slab: What is it?
A raft slab is a reinforced concrete slab that is fortified with integral concrete beams set in both directions. The strengthening or fortifying beams are known as “strip footings,” and that is because they run in parallel strips. The beams which are set around the outside are known as “edge beams.”
Raft slabs are usually designed in such a way that they follow Australian standard AS2870.
A raft slab is usually 4 inches (100mm) thick, with the slab portion sometimes built thicker – up to 8 inches (150mm) – so that it can span further or made stronger. The minimum thickness used in residential buildings is 4 inches (100mm) in raft slab construction and 3.35 inches (85mm) in waffle slab construction.
Benefits of Concrete Suspended Slabs and Raft Slabs
Concrete suspended slabs and raft slabs come with a lot of benefits. Here are a few of them:
Numerous aspects of modern residential buildings are designed to enhance user comfort as well as energy efficiency. You can decrease the rate at which you consume power – when cooling or heating your environment – with the use of features such as double glazing and insulation.
But the truth is that the thermal mass of concrete suspended slabs both absorb and also release coolness and warmth efficiently. This makes it much more energy-efficient than wood flooring.
Decreased cooling and heating, as well as increased insulation properties, are part of the apparent health benefits that come with using concrete suspended slabs.
However, in terms of safety, concrete is not found wanting. For instance, concrete suspended slabs or raft slab do not burn. So, if an unfortunate incident that involves fire occurs near or in your home, your concrete slabs will take no part in the issue.
This is what makes the use of concrete suspended slabs in two-storied homes a no-brainer.
Strength and Durability
Another obvious benefit of the use of suspended slabs is its strength and superior durability. Concrete suspended slabs are much more reliable and rigid compared to wood or any other type of second-story flooring material.
Gives More Space
Using suspended slabs in your two-story home offers a lot of space as you will have enough space for storing your stuff. Areas like those found underneath concrete stairs can be effectively utilized while batons integrated to the underside of concrete suspended slabs indicate that ceiling plasterboards can be secured without deviation to the slab.
The outcome will be a maximized ceiling height, which provides for a consistent finish throughout the property.
Traditional wood flooring is well known for noises, especially when kids are stomping all over the house while you are taking a nap in the lounge downstairs. That can be pretty annoying.
But you will not encounter such problems with suspended slabs. You will enjoy the sweet silence in your home when the staircase is also constructed with concrete.
That means anyone who wants to can clomp up and down the stairs and no one will be the wiser, thanks to the noise-absorbing capacity of concrete.
Building homes that last a lifetime is the target of a professional building contractor. And to achieve this, materials that will last a lifetime have to be in play. One of the numerous innovative product implementations that a home builder can put in place in a well-designed home is concrete suspended slabs.
