From the early part of the twentieth century it became accepted practice to cover the site of buildings with a layer of concrete some 100 mm thick the concrete oversite or oversite concrete.
Concrete oversite floor.
In building terms the oversite refers to a layer of concrete that is used to seal the earth and create the ground floor of your house.
As nouns the difference between oversite and oversight is that oversite is a flat solid layer of concrete serving as a base for flooring while oversight is an omission.
These are laid on top of the inner leaf of the walls sitting on the dpc but with no mortar bed.
At the time many ground floors of houses were formed as raised timber floors on oversite concrete with the space below the floor ventilated against.
The floor is made up of precast concrete beams shaped a bit like the rails on a train track.
Something that is left out missed or forgotten.
The 440mm gaps left between the beams are then filled with standard size foundation blocks until the entire floor is one flat slab.
An underlayer of concrete below a slab or other flooring.
