The pumping system should deliver the material to the working area in a condition suitable for laying. Experience has shown that most efficient pumping is achieved when well-graded sand with not less than 15 % passing a 0.250 mm sieve is used. It is often difficult to pump satisfactorily screed material richer than 1:4 by mass at water contents suitable for levelling screeds.
