The screed material proportions to meet the specified ISCR should be chosen by the contractor.

In making the selection account should be taken of the type and thickness of the flooring to be applied and the loading to which it is likely to be subjected. In general, cement and sand screeds are not suitable if heavy powered trucks or heavy equipment fitted with small hard castors are to be used.

For these types of use, the base should be concrete or a sand concrete screed compressive strength class C 25/30. Higher strengths might be required in some situations.

care should be taken if proposing to use a floating screed in a situation which will be subject to heavy loads, to ensure that the installation will have sufficient load-carrying capacity to perform without deformation.

The ISCR should be assessed by means of the BRE screed tester.
