I’m going to lay a paved pathway in my garden but am wondering if I can leave a 100mm gap between pavers and then fill the gaps with something that will stay solid? I’m reluctant to create a stepping path with big gaps and gravel as there are trees overhead that drop heaps of leaves so it’d be a pain to clean, but would like small gaps filled with something that won’t move when I use a blower to clear the leaves from the path.
Thanks!
