I am looking for stepping stones and visited Sg Buloh. All they have are concrete stepping stones in various sizes. But I am thinking of using wooden or timber stepping stones instead. I thought of old railway sleepers but was told that it is too heavy and too expensive.

What about local hard wood? Can I cut them into size (1' x 2') and place them on the ground without them rotting? I know they use those wood for the pergolas and it seems OK but will they last if they are used for stepping? Anyone tried it before?
