Building control have told use the floor will need to be removed and insulated with 75mm kingspan and then covered with concrete, we were hoping that as we were not doing anything with the floor increasing or decreasing size we would not have to do this and it would save us a lot of money in the build.
Concrete floors do not have to be drab and grey. Oh No SANS10400 are the Building regulations in South Africa, and both international and national standards, are fundamental to successful building and construction projects, both big and small. Building Regulations NBR Introduction
B.7.1 Construction F1: Ground floor: concrete slab-on-ground. Insulation under slab or under screed. For continuous and uniform insulation under the full ground floor area, the insulation thickness required to achieve prescribed U-values for slab-on-ground floors varies depending on the floor area to exposed perimeter ratio as shown in Example A4 in Appendix A.
Quality floor construction includes good subgrade compaction, even thickness slabs, low-slump concrete, straight bulkhead lines, and control cuts spaced 24 to 30 times the slab thickness. Common mistakes in concrete floor slab construction can be avoided with proper base preparation, mix design, placement, finishing, and curing.
A typical floor for a garage generally consists of hardcore, sand blinding, DPM damp proof membrane and concrete. It is considered to be good practice to place reinforced mesh within the concrete as this can reduce the chances of cracking from the load weight of a vehicle.
News from Kansas provides a harsh reminder that building codes are often inadequate, at least when it comes to requirements for concrete slab foundations.
When concrete was used, wall-to-wall carpet was a popular floor covering in the bedrooms, living room and sometimes the dining room. Linoleum , vinyl sheet, vinyl tiles, quarry clay tiles or cork tiles were commonly used in wet areas such as the kitchen, bathroom and laundry.
The Concrete Centre provides material, design and construction guidance. Our aim is to enable all those involved in the design, use and performance of concrete and masonry to realise the potential of these materials.
Suspended concrete ground floors 19 Sub-section 3.2 Walls Those involved in the design and construction of a building may be required by the relevant building Building Regulations are made for specific purposes, e.g. to provide, in relation to buildings, for the health,
it can fit very well with the idea of Flexible design because if a house needs to be modified at some point to provide an upstairs flat then sound and fire insulation will be required by the building regulations and this can easily be achieved with a concrete floor.
As well as the small selection of foundation, wall, floor and roof construction detail drawings shown here, many of the Building Notes have a related Construction Detail Drawing, with specific dimensions eg rafter sizes, spans, insulations types, for purchase with the Building Specifications.

SAMPLE CODE REQUIREMENTS FOR FINISHED CONCRETE BASEMENTS. Ceiling/Floor Draftstopping, Firestopping, Smoke Detectors On basement renovation projects it is usually considered to be very important within the building construction plans to identify either graphically or by notation both existing and new construction.
The building regulations require that floors achieve minimum thermal performance values U-values a measure of how quickly heat will travel through the floor , and this affects the amount of insulation required.
This construction is similar to the timber floor above, but uses either pre-cast concrete planks or small pre-cast concrete beams with concrete blocks laid between the beams. They can normally span greater distances than timber joists.
Beam and block floors are the most popular solution when building a ground floor on self build sites. Concrete slabs are a good alternative for small extensions where beam and block floors are uneconomic Beam and block systems which utilise insulated blocks can provide an even quicker installation
Concrete footings may also be needed for projects such as a deck, pergola, retaining wall or other types of construction. If you know your soil bearing capacity, following these practical guidelines will ensure strong footings.
Floor screeds A floor screed is usually a cementitious material made from a 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit.
The Building Regulations require that, in some circumstances, the floor should contain insulation to achieve the heat loss estimates for the room and/or house as a whole. This has led to an increased use of heated concrete floors or screeds.
