I have a garden of many levels and need to put down a “landing” step at the junction of 4 paths. Side one is a step down from an existing patio, side two will be a step down from a lawn with a brick retainer, side 3 is level with the lawn and side 4 will have a step down from it down to a slate path with a brick retainer. The step itself measures 1550 x 1300 mm and will be covered with Blue Diamond Pavers.
The area is level compacted soil, but it has been prone to sinking in the past due to tunnelling from rodents and everybody stepping off the patio on to the same small patch.
What substrate do I need under the pavers? I was thinking of using paving slabs with a dry mx on top with the pavers set into it, but I’m open to suggestions from people who actually know what they are doing.
Budget and access are an issue, but I don’t want it to sink or crack.
