evening chaps!
a client wants me to lay a slap of concrete down for a shed base. how deep should i dig? would i need to hardcore first? plastic sheeting as a damp barrier? shes a bit fussy and i want to be bang on the right process of doing it. there is also a big f*** off tree about four metres from the intended plot. problem? shed will be timber i suspect. :'(
cheers dudes
