7Screed rails or battens are used to:
- Ahelp delivery of screed material to the workstation

- C tamp down the surface of the screed
- Dform channels for drainage
8The purpose of a damp proof membrane is to:

- Bassist in the curing process
- Callow the screed to dry out quickly
- Dprevent the passage of moisture
9Cracking of large area floors may be reduced by:
- Ause of more cement
- Buse of expansion strips
- Cadding more sand
