Operation P 35A
4.8 Operation
Procedure
Perform the procedure below to perform a typical screeding of concrete.
1. Establish wet pads for wet screed guidance. Place wet pads (a) in strips no less
than 0.6m (2.0 ft) wide.
Note: Hand tools such as magnesium floats are used in conjunction with a laser
receiver, transit level, or grade stakes to establish the proper elevation of the pads.
2. Use a float to strike off or build up the level of the fresh concrete to the desired
grade. This is usually marked with an “X” (b) to signal the screed operator that
grade has been established. A minimum of two areas should be marked per
length of screed blade used to strike the entire pad.
3. Place the blade on the pad and strike-off perpendicular to the strip axis (c). Use
the marked pads as elevation guides.
4. Place concrete between the strips (d) and use them as “wet forms” for the rest
of the placement. Strike-off at this point will be parallel to the axis of the initial
wet pads of concrete.
