Internal Waterproofing Compliance Certificate (NCC 2019)
Ensure your bathrooms, laundries and internal wet areas meet all waterproofing and NCC compliance requirements with our Internal Waterproofing Compliance Certificate, professionally designed for New South Wales residential and commercial building projects. This easy-to-use, fillable certificate provides formal confirmation that all internal waterproofing works have been completed in accordance with AS 3740, manufacturer specifications, and the NCC.
Ideal for licensed waterproofers, builders, renovators, bathroom installers, designers and certifiers, this certificate verifies that key waterproofing elements—such as membrane installation, substrate preparation, falls to floor wastes, junction sealing, shower recesses, wet area protection, and drying/curing requirements—have been completed and inspected correctly. It is commonly required during Construction Certificate (CC), Complying Development Certificate (CDC) and Occupation Certificate (OC) submissions to prevent delays, non-compliance notices or costly rectification.
Simply download the template, enter your project’s waterproofing details, and submit the completed certificate to your certifier as part of your final wet area documentation package.
Ideal for:
Bathrooms, ensuites, laundries, powder rooms & internal wet areas
Residential and commercial builds & renovations
DA, CC & CDC projects in NSW
Occupation Certificate submissions
Licensed waterproofers and builders requiring AS 3740 sign-off
Wet area membrane systems requiring formal compliance documentation
