Wardell technician testing a waterproof membrane — Membrane testing

The owners corporation engaged Wardell after an engineer's regulated design report found concrete spalling, cracked render and a failed waterproof membrane on the Level 5 awning slab, which overhung the heritage-listed temple courtyard. We removed the 25-metre awning and installed a new Ardex waterproofing system, concrete hob and Colorbond capping, with gantry hoarding and catch decks protecting the courtyard below.
