Ground bearing floors, also known as ground-supported floors or slab-on-grade floors, are a type of floor construction where the floor slab is directly supported by the ground beneath it. This method is commonly used in building construction for its simplicity and cost-effectiveness.
Characteristics
Direct contact with ground: the concrete slab is poured directly onto the prepared ground surface, usually after a layer of compacted gravel or hardcore has been laid.
Load distribution: the weight of the floor and any loads it carries are distributed directly to the ground, reducing the need for additional structural support.
Construction materials: typically made of reinforced concrete to provide the necessary strength and durability.
Insulation and moisture barriers: often includes a layer of insulation and a moisture barrier to prevent dampness and heat loss.
Applications
Residential buildings: often used in houses and small residential buildings.
Commercial buildings: suitable for warehouses, factories and other commercial structures where large, open floor spaces are needed.
Garages and sheds: commonly used in the construction of garages, sheds and other outbuildings.
Construction process
- Site preparation: clearing the site, removing topsoil and compacting the ground.
- Sub-base preparation: laying and compacting a layer of hardcore or gravel to create a stable base.
- Moisture barrier and insulation: installing a damp-proof membrane and insulation layers as required.
- Reinforcement: placing steel reinforcement mesh or bars to strengthen the concrete slab.
- Pouring concrete: pouring and levelling the concrete to form the floor slab.
- Curing: allowing the concrete to cure properly to achieve the desired strength.
Overall, ground bearing floors are a practical and widely used flooring solution in many types of construction projects, providing a stable and durable surface that supports the structure above. Get in touch with us to find out more about ground bearing floors within Yorkshire.
