Building raised flower beds

Baloooo X
2 years ago
I have clay soil in some patrs of my garden and want to build some flower beds (60 cm tall by 300cm long) next to the brick boundary wall using standard breeze blocks to aid drainage and help plants grow better .
What type of foundation / footings is needed on clay soil to prevent the wall from cracking / collapsing? Do I need to lay bed of cement into the trench on top of the gravel to help drainage? Also how deep does the trench needs to be ? And finally do I need to line the inside of the beds with damp proof membrane ?
Many thanks
