I am considering Besser block for a retaining/raised garden bed. The garden beds will run down a slight slope. Approx 800mm drop over 5 meters. So they will be cut in. Max height 3 tiers, majority will be 2 tier.
Decent footing, double the width and depth of the blocks with Rio every 3rd core. Would I need to worry about mortar joins or could I dry stack them and just fill with grout?
I plan on finishing in Dulux Texture paint. And waterproofing the inner walls.
Just thought a dry stack might make the texture coat look better that and the fact I've never layed Besser block before as I've always used dry stack retaining blocks. What do you think?
