When used in combination with approved waterproofing components, Rasogum+ supports compliance with the following New Zealand Building Code clauses:
Rasogum+ has been widely used throughout Europe and New Zealand in both residential and commercial internal wet area projects. It has a long-standing record of performance under tile finishes in bathrooms, laundries, and kitchens, and is trusted by architects, waterproofers, and tilers for reliable waterproofing outcomes.
In New Zealand, it is accepted by councils when used as part of internal waterproofing systems that include tested and BRANZ Appraised membranes. Its compatibility with New Zealand’s regulatory requirements, including NZBC Clause E3 Internal Moisture and guidance from the IWAM Code of Practice, supports its proven use on council-approved projects across the country.
Rasogum+ is a flexible and durable internal waterproofing membrane designed to accommodate substrate movement and thermal cycling, with resistance ranging from -30°C to +80°C. Once cured, it forms a seamless, water-resistant barrier that supports long-term protection beneath ceramic, porcelain, or stone tiles.
This low-odour, low-VOC membrane holds a Eurofins A+ rating, making it suitable for enclosed or sensitive indoor environments such as bathrooms, laundries, kitchens, and healthcare spaces. It contains no Red List materials and complies with NZBC Clause F2 for hazardous building materials.
Rasogum+ aligns with the IWAM Code of Practice and the TANZ Best Practice Guide for internal wet area waterproofing, ensuring consistency with recognised New Zealand installation standards. Its ease of application by brush, roller, or trowel delivers efficient coverage and strong substrate adhesion, and it is compatible with a wide range of tile adhesives and under-tile heating systems.
Technokolla’s tiling and waterproofing systems offer BRANZ-appraised performance for NZ residential & commercial projects, complying with NZBC, and IWAM best practice; backed by a 15 year warranty.
