Raft Concrete Floor Slab

Ready super slab is an above ground engineered raft foundation system commonly known as a raft foundation pod floor waffle slab or floating foundation that delivers real benefits over a conventional concrete floor and foundations.

Raft concrete floor slab. Concrete is poured in one operation creating a slab that covers the entire floor area. For low rise buildings on poor ground the floor slab can be designed as a raft to act as the foundation. They offer considerable benefits over conventional block base type slabs at significant cost savings reduced construction time increased strength and superior insulation. While celotex pir boards have a good compressive strength they cannot be laid below a raft slab and take the structural load of the building.

Raft slabs are now a well established and proven type of concrete floor slab. Some stiffened raft slabs known as waffle raft slabs use void formers at regular intervals forming closely spaced deep reinforced beams criss crossing the slab underside. Raft foundation is actually a thick concrete slab resting on a large area of soil reinforced with steel supporting columns or walls and transfer loads from the structure to the soil. Ribraft floors are an innovative method of raft concrete floor construction is quick and efficient to lay it offers excellent insulation benefits and is seismically strong.

Each raft slab is engineer designed to suit onsite conditions. Reactive soil sites can be difficult to build on but floating stiffened concrete raft slabs cope well with these conditions. A raft slab is reinforced concrete slab on ground that is strengthened with integral concrete beams in both directions. An engineered raft foundation and flooring system that offers real benefits over a conventional concrete slab.

Don t waste your energy. Build a healthy and more cost effective home. Fully insulated maxraft slabs are designed specifically to increase the performance of your home from the foundation up. They consist of a perimeter footing edge beam and a series of narrow internal beams strip footings at one metre nominal centres running each way.

Raft slabs in australia are designed to comply with australian standard as2870. Usually a raft slab is used as the foundation for new houses and extensions. The slab is spread out under the entire building or at least a large part of it which lowers the contact pressure compared to the traditionally used strip or trench footings. Usually mat foundation is spread over the entire area of the structure it is supporting.

Raft foundations sometimes known as mat foundations are a large concrete slab which can support a number of columns and walls.
