In building construction floor screed can be an essential structural process and it is important to have the knowledge of finishing floors. a good finished floor will look attractive and will last much longer. A flooring screed as the name suggests is normally used on floors of structures. Otherwise it’s a layer of material commonly cementitious or concrete laid in situ, on top of which other finishing materials can be applied directly. The layer can also be left to dry and achieve a rough cast or a raw effect. The functions of the layer is highlighted below:
• They obtain or determine a defined level or position
• They act as the wearing surface.
• They hold the final flooring
Classification of screed floors
This is done according the method used or the level of technology. We have the following ways of screeding. They include:
• Fully bonded to the base- the material thickness is 25– 40mm.
• Unbonded – a DPM (dump proof membrane) is placed under the screed. For the purpose of preventing water capillarity. A PVC is normally used. The material has a thickness of about 50mm.
• Floating- has thermal or impact sound insulation installed.
Caution should be taken to carefully lay the screeds well to avoid affecting the quality of the floors.
