Screed Designing Buildings

The optimum thickness of a sand and cement bonded screed is generally in the region of 25-40 mm. Some calcium sulphate flowing screeds can be laid at a minimum depth of 12 mm. Care must be taken during the laying process to ensure de-bonding does not occur as this can lead to instability and ultimately, the screed may fail. Unbonded screed
