Find trusted waterproofing contractors in Coogee WA

I’m converting part of an existing space into a small bathroom on an existing concrete slab. I need an experienced bathroom waterproofing/wet-area tradesperson to: • Prepare the concrete floor • Prepare/create the shower fall to the floor waste • Waterproof the bathroom floor • Waterproof the shower area and required wall-floor junctions • Properly seal around the floor waste and penetrations • Complete the work in accordance with WA requirements and the applicable Australian Standards • Provide waterproofing compliance documentation/warranty on completion The bathroom is small and I will use waterproof wall panels rather than traditional tiled walls. Please quote for labour and materials separately and advise what you would need completed before you commence. Please only respond if you have experience with bathroom wet-area waterproofing and can provide appropriate compliance documentation.
