    Abstract: A clayward-facing side of a perforated support structure is placed against a wall with exposed clay. Perforations allow fluid transport through the perforated support structure from an opposing side of the perforated support structure to the clayward-facing side. After bringing the clayward-facing side in physical contact with the wall ,the opposing side is exposed to a water-containing fluid, whereby allowing the water containing fluid to contact the wall through the perforations. Water is absorbed in any clay that is exposed to the perforations, which causes local swelling of clay comprised in wall parts that are exposed to the perforations. The shear strength of the saturated clay prevents the clay from migrating though the perforations to the opposing side.
