Detailed Drawing of Raft Foundation
Click to View
Picture
The concrete raft is supported on a compacted hardcore base which extends out past the edge of the raft.

The edge of the raft is stepped, creating a toe, which allows the outer leaf of the wall to continue below ground level.

Picture
It is vital that the concrete slab is strengthened by the use of steel reinforcement.

A radon barrier is installed to form a continuous seal on the entire footprint of the house.

A Damp Proof Course is installed in order to repel any rising moisture. It is vital that the DPC is carried up into the blockwork to form a water tight seal over the entire floor area.

The DPC must run through the blockwork at a minimum of 150mm above finished ground level.
