Block and Precast Beam flooring

The use of Precast Beam and Block flooring has become an economic alternative to suspended timber flooring in domestic properties.

The typical construction is shown below with the pre-cast beams with light weight concrete blocks infill. Air bricks/ventilators are fitted through the outer walls, facilitate air movement under the floor.

Although the above illustrations show a block internal skin above the floor, Block/Beam floors are also used for ground floors in timber frame buildings.
