A floating slab is a specific type of concrete foundation that sits directly on the ground without any external support. It consists of two main stages: individual footings are first cast, followed by pouring the central floor of the slab. This unique construction method minimizes ground preparation and is often referred to as a monolithic slab.
Floating slabs are employed in structures with low bearing capacity requirements. Ideal for smaller constructions where a deep foundation is unnecessary, and additional infrastructure is not required. Common applications include manufacturing workshops, sheds, and garages.
Cost-Effectiveness : Choosing a floating slab offers one of the most economical foundation construction methods. Traditional foundations necessitate strip footings with frost walls, involving more excavation, concrete, and labor. Floating slabs, by contrast, minimize costs.
1. Site Preparation : The initial step involves inspecting the site, clearing it of debris, and creating an excavation plan.
2. Excavation : Excavate the site to the desired level, creating drainage channels for water runoff.
3. Laying Gravel Base : Spread gravel over the area to facilitate water drainage.
4. Reinforcement For Slab : Prepare reinforcement in accordance with structural design, ensuring proper distribution.
5. Shuttering : Initiate formwork, ensuring a smooth surface and proper alignment. Fix cover blocks to prevent formwork opening during concrete pouring.
6. Concreting : Mix concrete on-site or use ready-mixed concrete. Compact thoroughly and remove shuttering after 24 hours.
7. Curing : Cure the slab for seven days by spraying water.
