Building an extension and tying in the new cavity wall to the existing stone wall.The stone wall now becomes an internal wall and i know that if it was a cavity wall then a vertical DPC would be inserted right through the exterior leaf of the old wall at the point between where the two new leafs tie in.
How is a vertical DPC achieved in a solid stone wall?i.e no cavity.
