In most cases this will be when the foundations have been laid and the walls have been built up to the damp proof course.
Extension solid floor construction.
Part 3 of the build the concrete slab.
If you have built an extension or new home then there will come a point when you are ready to pour a concrete slab.
There are three general types of ground floor construction.
The advantage of a solid ground floor is the elimination of dry rot and other problems normally associated with hollow joisted floors.
Before this happens there are several key preparation stages that need to be carried out.
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.
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.
Undoubtedly insulation is easier to provide with the solid slab and beam and block type of flooring as it simply becomes part of the construction sandwich.
Insulating the floor structure.
Today s building regulations and standards require the solid floors of most buildings to have high levels of insulation and high compressive strength as well as impermeable barriers to prevent moisture migrating through the floor into the room.
In timber suspended floors its placement is more complicated but there are many practicable solutions.
How to insulate solid floors.
In this video we show how we prepared it and laid it.
This is probably the most well understood intermediate floor structure and generally the most affordable.
In this video is the third part of the videos.
It is not possible to lay insulation underneath a solid floor so any insulation will need to go on top.
They keep the depth of the floor construction down meaning less excavation and are easily handled and.
The disadvantage is that the floor is less resilient to walk upon and may.
These joists can be used with any building system with generic details available for how each joist should be installed into the best known construction types including masonry cavity walling and timber frame panels.
In a solid or ground bearing because it is continuously supported by the ground across its whole area concrete floor the choice of insulation position relative to the concrete slab is commonly linked to the building s heating system.
