Residential Construction Methods
A suspended slab is primarily used as either a ground floor solution or as an alternative to timber for upper floors. Typically built from either precast concrete, block and beam, or reinforced concrete that is cast in-situ, a suspended slab floor is set apart by the void beneath the structure.
- Ground Floor: - the void beneath the structure is key to understanding the benefits of using a suspended slab for your ground floor. As this space allows for increased air flow and ventilation, that helps prevent the accumulation of mold and dry rot in areas with damp soil.
- Upper Floors: - as an upper floor construction material in multi-story homes, suspended slab concrete offers a superior alternative to timber. This is thanks to its strength, durability, soundproofing qualities, and energy efficiency.
Constructed from shallow foundations, a raft slab is a quick and inexpensive option that is perfectly suited to smaller builds, such as extensions and outbuildings. A raft foundation can also be used to provide access to a traditional foundation if required by physical constraints. When dealing with raft slabs, it’s important to get the right raft slab for your project, something that requires a great deal of professional expertise and knowledge.
There are four main types of raft slab:
- Solid Slab: - the most common type of raft slab, a solid slab is suited to projects where the load bearing requirements are light and spread evenly throughout the structure
- Slab Beam: - if the load bearing points are distributed unevenly, then your project will require a slab beam raft
Depending on the nature of the task there are a variety of different concrete techniques and equipment that should be used, making it vitally important that you bring in a specialized professional to ensure the work is done properly and effectively.
