General Rules of Screed Flooring
Floor-screeds laid in large bays can curl as they dry and shrink and can crack later when loaded if the bond to the base is insufficient. The use of un-bonded and floating levelling screeds might not be acceptable for some screed flooring which would be affected by excessive curling or movement at joints. Of the three types of construction (bonded, un-bonded and floating) hollowness, curling and cracking of screeds cannot be avoided.
Screeds are normally tested in accordance with BS8204 using a BRE screed tester with results recorded and measured in three categories A, B & C. Heavy use is categorised as Category A with light use as category C.
Surface Regularity is classified as follows: SR1, SR2 and SR3 with SR1 a maximum permissible departure of 3mm from the underside of a 2m straightedge. SR2 is 5mm and SR3 is 10mm.
Departure from Datum under British Standards is up to 15mm however +/- 10mm is expected to be achieved by a competent contractor
