hello-
I am designing a curved brick sitting wall (say, 380mm width)with a (concrete-based) flag coping (width of 400mm) Will two half-brick thick walls with occasional piers be stable enough? Filled with hardcore/rubble? They don't make butterfly ties that wide, do they?
Or should I do a block wall (double block wall?) with brick skins on either side?
As always, I want to keep the cost down, but it must be stable and long lasting. Children will undoubtably walk along the wall, family members will sit there for outdoor dining, etc.
Assuming this will be no higher than around 500mm, just use two single skins. You could leave the centre hollow, or fill it with a concrete block, if you wish.
Personally, I'd build it 3 bricks wide (350mm)and not bother with any piers.
