Help with laying concrete pad
Hey yall, so i got one of these garden sheds, size is 190cm by 122cm. I have dug out a rectangle into the ground slightly bigger than the fram i built for the concrete. The frame timber is 10cm deep so im thinking making the concrete that deepth.
Its going to hold a washing machine and dryer. The soil is quite soft so ive dug 30cm deep, do i need to use gravel or small rocks to lay down the base? Im thinking 10cm gravel and 5cm sand? I also have some small mesh i got for free id lay down.
When the cement is finished how do i make the surface nice and smooth? I seen some people will use the trout and smothen the top and edges but then i notice they come back a few hours later to spray some water and go over with a brush?
Also is this cement bags all right to use?
