Thanks for the help guys much appreciated.

Finally getting around to sorting this now! Just wondering what size stone /gravel i should use 10 mm or 20 mm in my cement mix
1 cement + 2 sharp sand + 3 gravel (10mm or 20mm) ?

Bang in any stone thats available, leave the fill wet and proud, and when it begins to go off tamp it down to a trowelled smooth surface.
