Damp-proofing rods are available with BBA approval. The rods are placed into holes drilled in the mortar course and the active ingredients diffuse along the mortar line before curing to form a damp-proof course. [53] Damp-proofing rods are usually supplied in 180mm (7") lengths suitable for inserting into a 9-inch thick wall.
A metal damp proof course (DPC) between the stone foundation and brick wall. Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.
The purpose of a Vertical Damp Proof Barrier is to prevent the ingress of damp and water into subterranean structures such as basements, cellars, tunnels and earth shielded buildings. (Also known as Earth sheltered buildings ).
Vapor retarder paints (for the air-tight drywall system, for retrofits where finished walls and ceilings will not be replaced, or for dry basements: can break down over time due to being chemically based). Extruded polystyrene or foil-faced foam board insulation. Exterior grade plywood, 0.70 US perm (40 SI perm).

These soil surfaces on the Great Wall are covered by a “living skin” of tiny, rootless plants and microorganisms known as biocrusts that are a source of the heritage site’s staying power ...
