Concrete slab floor construction was often used for internal garages or lower levels of split level houses, with suspended floors used for other parts of the house. Construction details Excavation Construction started with the removal of topsoil and excavation for footings.
Suspended slabs are above-ground level slabs which are not directly in contact with the earth. They are commonly used to create floors for the upper storeys of houses, but can also be sat on top of pre-constructed walls to form a ground floor.
Concrete slab floors come in many forms and can be used to provide great thermal comfort and lifestyle advantages. Slabs can be on-ground, suspended, or a mix of both. They can be insulated, both underneath and on the edges. Conventional concrete has high embodied energy.
Suspended floors. A suspended concrete floor is a floor slab where its perimeter is, or at least two of its opposite edges are, supported on walls, beams or columns that carry its self weight and imposed loading.
Concrete Construction: Resources for contractors and specifiers including construction methods, materials and practices. a comfortable slab-on-ground floor can be constructed with little more difficulty than the placing of a concrete slab for any other purpose. Good drainage is a requirement with slab-on-ground construction.
Tolerances for Suspended Concrete Slabs ASCC Position Statement 24 Concrete floors are often placed on a sus- Guide for Concrete Floor and Slab Construction. ASCC concrete contractors will work with all parties in addressing these issues. If you have any questions,
Suspended Concrete Flooring Speedfloor is a suspended concrete floor system using a cold formed steel joist as an integral part of the final concrete and steel composite floor. The joist is manufactured from pre-galvanised high strength steel in a one pass rollformer giving a high degree of accuracy at a fast production rate.
Do the floor joists under the concrete floor remain to support the floor, and are they sized to carry the dead and live loads, or is the concrete slab spanning from foundation to steel beam to foundations wall, the joists being only form-work which is removed? Most of the time there will be a steel beam in the center of these suspended
homeSPAN concrete floors create a strong, studier home, which is less prone to movement. Using homeSPAN at ground floor level enables the base of the house to be filled with site spoil eliminating the need for expensive hardcore fill. Under Floor Heating is more efficient with a homeSPAN floor. When the homeSPAN slabs are placed on site
Suspended slabs are slabs that are not in direct contact with the ground. They form roofs or floors above ground level. Suspended slabs are grouped into two types: one way slabs which are supported on two sides; two way slabs which are supported on all four sides. The way a slab spans its supports has a direct impact on the way in which the
In many domestic and industrial buildings a thick concrete slab, supported on foundations or directly on the subsoil, is used to construct the ground floor of a building. These can either be "ground-bearing" or "suspended" slabs. The slab is "ground-bearing" if it rests directly on the foundation, otherwise the slab is "suspended".
Slabs transmit the applied floor or roof loads to their supports. Slabs may be classified into two main groups depending on whether they are supported on the ground or suspended in a building. Ground slabs. Ground slabs are those slabs that are poured directly into excavated trenches in the ground. They rely entirely on the existing ground for
Composite Floors. Precast concrete composite flooring is a high quality, economical concrete floor construction where long spans and/or high load bearing capacities are required. Suspended concrete floors are constructed using prestressed planks supported by either masonry walls or a supporting steel frame structure.

The color of concrete slabs used to be a major disadvantage, as concrete only came in gray. However, there are options for coloring and decorating your concrete slab floor. You can put carpet over the concrete for instance, but for homeowners who want to utilize the concrete instead of hide it, acid stain is a more common route.
Suspended concrete floors. There are occasions where due to the ground conditions that a suspended floor is needed rather than a ground bearing slab. These include soil with a low bearing capacity, sloping sites, soils containing aggressive chemicals and those with high water levels Marshall and Worthing, 2000 .
Suspended concrete floor. The construction of suspended concrete floors is similar to that of timber but can span greater distances, and offerings better sound insulation properties. A simple reinforced concrete flat slab is not usually economical as a suspended floor spanning over 5 m.
enter indoors through the slab on ground. slab curling and shrinkage, radon, vapor intrusion, Because the construction of concrete floors on the ground necessarily focuses a great deal of attention on the allows forming of complete structural suspended slabs on
The subbase, according to ACI 302.1, Guide to Concrete Floor and Slab Construction, is a layer on top of the subgrade of compactible , easy to trim, granular fill that will remain stable and support construction traffic.

This guide describes how to produce high-quality concrete slabs-on-ground and suspended floors for various classes of service. It emphasizes such aspects of construction as site preparation, concrete materials, concrete mixture proportions, concrete workmanship, joint construction, load transfer across joints, form stripping procedures
Suspended slabs differ from non-suspended slabs because they aresuspended above the ground via beams. The concrete floor must be of a Supended slab are slab not sit on the ground directly
Suspended Concrete Slab. Suspended concrete slab is referred to a cement slab that is not in contact with the ground. This type of concrete slab construction requires different concrete slab design from the one we normally see that is cast on the ground. The most common application of suspended slab in residential construction is used at garage floor where below the garage floor is a storage

To a large extent, suspended timber ground floors gave way to solid slab concrete floors throughout much the 20th century and then, from around 1976 onwards, following a prolonged period of drought with many foundation and oversite failures, suspended concrete beam and block floors started to gain prominence.
concrete slab-on-ground floor systems and suspended floors suitable for residential buildings ranging from single, detached houses to medium density buildings of apartments and flats. For slab-on-ground floors it provides an understanding of the footing/slab selection, design, detailing and construction requirements contained in AS 2870 and
The design of slabs on ground should conform to the rec-ommendations of ACI 360R. Refer to ACI 223 for special procedures recommended for the design and construction of shrinkage-compensating concrete slabs on ground. The de-sign of suspended floors should conform to requirements of ACI 318 and ACI 421.1R. See Section 1.2 for relevant work
