Concrete ground floor section detail.
The advantage of a solid ground floor is the elimination of dry rot and other problems normally associated with hollow joisted floors.
Resistance to ground moisture fire safety resistance to passage of heat resistance to passage of sound.
Steel reinforced slabs typically between 100 and 500 mm thick are most often used to construct floors and ceilings while thinner mud slabs may be used for exterior paving see below in many domestic and industrial buildings a thick concrete slab supported on.
The disadvantage is that the floor is less resilient to walk upon and may.
Ground bearing and suspended.
Under slab vapor retarders or waterproofing.
Founded in 1904 and headquartered in farmington hills michigan usa the american concrete institute is a leading authority and resource worldwide for the development dissemination and adoption of its consensus based standards technical resources educational programs and proven expertise for individuals and organizations involved in concrete design.
To ensure a level finish to the floor a layer of screed is added over the top of the concrete which consists of sand and cement.
A solid ground floor consists of a layer of concrete which in the case of a domestic building will be the surface layer brought up to ground floor level with hardcore filling under it.
In the uk the building regulations approved documents provide guidance on some of the requirements of ground floors.
The slab is constructed on well compacted granular fill crushed stone or marl.
The ground floor is made up of suspended concrete slab or beam and block floor supported by the external and internal load bearing walls which transfer the loads to the foundations below.
There are three general types of ground floor construction.
Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate.
Alternative floor slab detail.
There are two types of concrete floor system commonly used in residential construction.
Ground bearing floors shall be of adequate strength and durability and use concrete mixed and reinforced as necessary to support floor loads safely and resist chemical and frost action.
The mesh reinforcement in the slab is placed in the top with 1 covers.
Floor slab detail.
In typical office environments the concrete floor slab itself is comprised of 4 to 6 thick concrete reinforced with one layer of welded wire fabric at mid depth unless below the water table when hydrostatic heads may exert upward pressure requiring stronger construction.
A typical way of constructing a solid floor would be to provide a base of hardcore with sand blinding with a layer of concrete over that.
Both pre cast concrete planks or slabs can be used as well as cast in situ reinforced slabs along with beam and block systems.
It is the responsibility of the designer to ensure the reinforcing is design specifically for your project.
