So I want to do something like this. The raised beds I have are brick that has been rendered. The Rendering is essentially cracking and falling off. Moisture to partially blame? The raised beds do appear to have drainage of some kind as it never floods or anything. What would I need to do to tile onto brick? Do I need to seal the brick externally to prevent moisture seeping into the adhesive or anything special?
