I am building a garden bed, making use of some clay pavers that had previously been used as flooring for a tin shed. I have dug out the 3m x 1.2m wide area, and now have to do some bricklaying. I intend to have two and a half courses of pavers below ground level and half a paver above ground level. A man at Bunnings told me that cement should do the job but another man said that I should have a first layer of concrete for strength. Who is right?
Hope this helps @ennoh
do you think I need concrete as a base with 3 courses of clay pavers - or is this overkill?
Without the footing you risk the pavers/walls of your garden bed sinking over time.
The earth below changes in moisture and dryness, like timber does, so the pavers will sink, move, etc.
Better off doing it right from the beginning, save extra work/rework later on.
Sounds like a great project. We are looking forward to seeing you complete it now that the ever-helpful Pete has given you some advice. Feel free to post anytime you need a hand with anything - we have amazing members sharing helpful advice and inspiring creations every day.
Welcome to Workshop,
I had in mind maybe using concrete for the base layer - but should I also use between the pavers that are underground and not cement? Is it the case that when underground cement will perish more easily?
I would make a concrete base about 4 inches deep and 3 inches either side to lay the first course on, then lay each other course on top with brickies sand and cement between each course.
This is all that Jason on BHG would do.
