Hi everyone. I hope you can help.
Im about to lay some slabs on my patio, which measures 21m2 onto an already slanted concrete sub-base. I've read the great site advice and used the calculator to give me total amount of grit sand and cement needed, but i dont trust myself in the calculations.
ive come out with 1.7 tonnes of grit sand and 167kgs of cement which would give me a bedding of 35-50mm. Is that correct?
Another question I have is that I have one step leading onto the patio. Would I need to make a wetter mix of sand/cement in order to get the facing slabs to stick onto the step?
sorry if this sounds like stupid questions, but any help would be great!
Thanks a lot!
