Water ingress via the mortar in the wall was causing efflorescence and damp on the inside of this garage. Once the brickwork was cleaned, the cracks and joins were sealed with appropriate flexible waterproof sealant before being primed. Ardex WPM310 – External Facade and Roof Membrane created an impenetrable barrier to prevent future moisture penetration. AS 4654 is applicable to Waterproofing Membranes for external above-ground use.
