Our retaining wall moulds (like Keystone or AB-Block or nonamed moulds) follow in the same idea as the paver - moulds.
Most of the parts are bolded or interlocked an can be exchange easily - with our special frame for "retaining blocks" -
If your team is good in maintaining - like several of our customers - you can also exchange parts and get a new block (like with/or without cores) or different surfaces of the block.
Actually we have new projects in development (some in production) - Change the way of corebar and cores - see link
