• I'm thinking of that paving with gaps for my front garden, but DIY. If I'm digging down to lay a hardcore base for the paved bits, do I just leave topsoil in place where the gaps are?

  • Best method is non-woven geo-textile under the slabs,
    (prevents weed growth and soil-heave),
    with gaps filled with resin-bound gravel to ensure
    storm water can drain between the slabs into your soil.
