Surface water drainage is a classic situation of requiring both form and function.

A practical perspective from Warren Jennings of the Specialized team on building envelope system selection, compliance, detailing and project delivery.

In designing a surface water drainage solution, you must consider the performance of the design in service. This design must allow for stormwater to be disposed of without causing damage, nuisance, flooding, erosion, or water entry into buildings.

For specifiers working across Green Star, Homestar and other sustainability frameworks, coatings are no longer a purely technical selection. They are a critical lever in achieving both project performance and certification outcomes.

Exterior timber coatings operate in fundamentally different ways and understanding this is essential to making the right call for each application.

Integrated testing of plumbing and passive fire systems provides a greater understanding of how components perform together within a building system.

An area often queried is the management of stormwater passing through a membrane surface, typically a downpipe penetrating a membrane deck or canopy.

Condensation in roof spaces is increasingly common, but the solution isn't just ventilation. This article explores why controlling internal moisture at its source, combined with airtight construction and above sheathing ventilation, is the most effective way to reduce condensation risk in modern New Zealand roofs.

A look at how mineral silicate systems behave, how these systems differ from acrylic systems, and the key differences and uses of mineral silicate paint vs mineral silicate stain.

Below-ground waterproofing is one of the most critical elements of a building’s long-term performance. When it fails, the consequences can be costly, disruptive, and difficult to remediate. That’s why understanding the different waterproofing strategies — particularly Type A and Type B protection — is increasingly important for designers, engineers, and builders across New Zealand.
