Next step what should/shouldn’t be used for sub-base material, I was thinking about using anything I can get hold of to include but not exclusively:-
Bricks – engineering, clay, etc.
Blocks – aerated, dense, clay paving blocks, concrete paving blocks, etc.
Concrete – lumps of any strength, roof tiles, fencing posts, kerb stones/edger’s
Tarmac,
rockery stones,
gravel,
Any thing else, I haven’t thought of?
Cheers, Mike.
