Casali Membranes Now CodeMark Certified!

We’re pleased to share another exciting milestone, Allco has officially received CodeMark certification (CMNZ70177) for our Casali Dermabit/Dermafil Torch-On and Aderix Self-Adhesive Bituminous Membrane Systems. Approved and registered by MBIE, this certification further reinforces our commitment to providing compliant, high-performance waterproofing solutions that meet the evolving needs of the New Zealand construction industry.

CodeMark Confidence You Can Specify With
The CodeMark scheme is the highest level of product assurance available in New Zealand, offering formal recognition of Building Code compliance. For the Casali systems, this certification confirms compliance with NZBC clauses:

• B2 (Durability)
• E2 (External Moisture)
• F2 (Hazardous Building Materials)

Design Versatility with Trusted Performance
Certified for use on both concrete and timber roofs and decks, the Casali systems allow for a minimum finished fall of 0.72 degrees (1:80). This makes them ideal for a wide range of low-slope applications, while ensuring effective drainage and long-term performance.

At Allco, we’re proud to back quality products with industry-leading support and technical guidance. Our complete roofing range now includes CodeMark-certified TPO, bituminous membranes and Hydrotech hot melt, tailored to meet the demands of New Zealand’s diverse building conditions.
