You often ask whether demolition clay bricks can be used outdoors? Is the brick frost-resistant? Will it be damaged during winter? The answer is simple: any clay brick – regardless is new or old from demolition – can be built on the outside. There is one condition: the brick must be protected against rainwater and moisture from the ground. For this reason, every brick wall, every brick building, every brick fence must have a crown and must be separated from the ground by a waterproof membrane.
