Hi all, im planning on building a garage down the bottem of my garden. I have removed all the rubbish that was down there ready to start. My question is with the base, Can i just pack the clay down then use dpm and fill with concrete? or must i use sand / ballast ontop of the clay? The clay is pretty solid down there, ive hit it with a pick axe and it just bounces off. I wont be parking the car in there as its mainly for storage. Also what works out the cheapest, Ready mixed or mix myself? if its only a few £ for ready mixed then id have this. Thanks in advance all. Advice is greatly appreciated.
