Concrete Oversite Floor

The 440mm gaps left between the beams are then filled with standard size foundation blocks until the entire floor is one flat slab.

Concrete oversite floor.

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. These are laid on top of the inner leaf of the walls sitting on the dpc but with no mortar bed. So placed to prevent disturbance of the ground below to provide a relatively even and firm surface for the placement of the next layer and to keep out ground air and moisture.

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. An underlayer of concrete below a slab or other flooring. Oversite concrete is often reffered to as german floor by the laymen others mistook it for dpc however oversite concrete is the mass concrete that you pour to cover the entire lenght and breadth of a building on the ground floor to serve as a source of additional support to the structural stability of a building especially storey buildings. 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.
