9-Inch Solid Sandcrete Block

Solid sandcrete blocks for external walls and load-bearing internal walls, moulded to a 1:6 mix with sharp sand and cured fourteen days on the stack — not the seven that lets a yard turn stock over faster and sends you blocks that crumble at the corner when they are offloaded. A crushing test result from the current batch is available to anyone who asks for it. Delivered by lorry with offloading included.
