Hi, were doing a treated pine footpath. Brought 1.8m lengths 200w x 50mm, but will cut to 900 lengths for path width. Thinking of putting down sand base, than laying sleepers on top. First question - do sleepers need to be secured down to prevent warping? 2nd question is does cut end need treating? Saw on other posts that should possible treat, but recommended treatment is no good for in ground. If needs treating, can you recommend appropriate treatment.
Thanks
