AbstractCavity walls afford complete protection against rain penetration. The cavity wall must have a gutter at its base to collect leakage water and drains to direct water out of it. The two parts of the wall must be anchored together with metal ties that are corrosion resistant and adequately strong. The wall must have a cavity free of mortar or other material that may form a water bridge across it.
