    I was out visting a mate of mine in Malahide this morning.
    He is in the process of building a garden retaining wall of 20 feet long about 2 feet high.

    His bricks are 150mm wide and he has his trench dug out to 350mm wide and 250mm deep.

    I asked him was he using any 804/hardcore in the foundation trences,and he said No....He would just mix up the cement in a mixer and pour it straight in.

    So should he put in some 804 hardcore and compact it down,as a base for the concrete??

    Thanks.:)

    For a 2 foot high wall? Noddatall.

    For a higher wall (e.g. house extension) put some steel in the base. Steel will reduce/prevent risk of cracking if the earth moves.
