Suspended slab under construction, with the formwork still in place. Timber floors were originally designed to prevent damp. There are various pros and cons to these types of floor, some of which impact on the energy efficiency of the building and how you go about insulating them. A: A structurally reinforced slab-on-ground uses a composite of concrete and structural steel to support the design load. ANSI/ASSP A10.31-2019 Safety Requirements, Definitions and Specifications for Digger Derrick. It is not possible to lay insulation underneath a solid floor, so any insulation will need to go on top. However, it is unknown what the floor void conditions are, nor the effect of insulating such floors. As nouns the difference between floor and ground is that floor is the bottom or lower part of any room; the supporting surface of a room while ground is (senseid)(uncountable) the surface of the earth, as opposed to the sky or water or underground. Suspended floors are normally made up of 2 materials, either timber joists or a concrete beam system. The gap between joist is 300-350mm. E2/AS1 gives minimum heights of finished floor levels above ground for concrete slab floors and suspended timber floors, the measurements depending on whether there is grass or paving outside. Basement or ground floors – the concrete slab is directly supported onto a construction which may involve hardcore, blinding and other materials. Do you have a different opinion? So we will discuss Concrete or Timber floor systems. If there is extensive refurbishment work happening however, it may be a good time to look at floor insulation. Block and beam floors are a very popular type of suspended floor. It rests on beams spanning between supporting walls.

However, where the space between the concrete base and the floor is greater than 45cm, Fig 3 shows an alternative arrangement where the joists are supported in the inner wall, the size of joists is dependant on the span of the floor and there will be a limit on the span that can be accommodated but this is unlikely to cause an issue in a domestic property. Suspended timber floors need to have spaces underneath ventilated via air 'bricks' through the outer walls and gaps in any internal walls so that the air can move across the building underneath the floors to prevent the build up of moisture in the timber which could lead to fungal attack.
