sand/cement

[xxconfusedxx]

hi, just wondering if anyone could tell me how man 25kg bags of sand and cement it would take to make a base for tiles in the garden. the base will be 2 x 2M, and im told needs to be 6 inches thick. any thoughts? TIA

A rough calculation is that you require 18 cubic feet... here in the U.S. a bag of ready mix concrete will cover just under 1 cubic feet... hence 18 or maybe 19 bags...

What sort of tiles? ............ concrete slabs?

[xxconfusedxx]

no, outdoor ceramic tiles.......

I think you are going to need a 100mm thick concrete base to prevent any movement to lay thin? ceramic tiles with water proof adhesive and grout like you would in a bathroom or kitchen this may help http://www.source4me.co.uk/calculate_building_ materials.php?tab=0 hth Tez
