We have an old farmhouse/barn from around 1850. As part of insulating the exterior facade, the consideration is now being given to applying perimeter insulation. Problem: We do not have a foundation in the traditional sense.
No concrete slab, only rammed earth floor, but the floor was insulated below the screed and is thermally decoupled from the walls.
The exterior walls are built about 30 cm into the ground, then there is soil (clay/sandy soil). Exterior walls consist of field-fired bricks/solid bricks. Exterior walls are slightly damp in the ground area during winter, otherwise no significant problems. In the area of the former horse stalls, we had slight salt efflorescence with moisture, but we managed it well with lime plaster.
Question: Does masonry waterproofing make any sense at all or do we worsen something by doing so? How about the perimeter insulation? How much energy loss do we actually have in that area?
