Whittaker's Factory

Whittaker’s Factory

At Whittaker's factory Stage 8, we provided extensive sealing work to ensure the structural integrity and durability of both the interior and exterior elevations.

Our team expertly sealed the concrete column junctions to brick walls on the interior, using Sikaflex AT-Facade in grey to create a clean, cohesive finish.

The same meticulous approach was applied to the exterior elevations, where we sealed the concrete columns to brick walls, offering robust protection against weathering while maintaining a uniform appearance.

Old Bank Arcade

At Old Bank Arcade, our team expertly cut out and resealed movement joints along the building perimeter, enhancing durability and weather resistance.

Using SikaHyflex-250 Facade, we ensured the joints remain flexible to accommodate movement while maintaining a clean, long-lasting seal.

Working on this historic site required precision and care to preserve the building’s character while reinforcing its structural integrity against the elements.

At the Lyall Bay Surf Club, our team carried out precise sealing work to ensure durability and weather resistance in a harsh coastal environment.

We expertly sealed the windows and secured the connection between aluminium windows and concrete, providing a seamless and robust barrier against the elements.

Our work not only enhances the structural integrity of the building but also contributes to its long-term resilience against coastal weather conditions.

At the BNZ building, our team delivered precise sealant work across multiple areas to ensure both functionality and aesthetic appeal.

We meticulously sealed the aluminium services in the mezzanine ceiling and expertly detailed around toilet door closers, ensuring a seamless finish.

On the exterior, we sealed stonework, providing durable protection against the elements. Additionally, we applied cosmetic detailing around the doors and flashings.

Akau Tangi Sports Centre

Akau Tangi Sports Centre

At the Ākau Tangi Sports Centre, our team executed a comprehensive sealant replacement and joint repair project on the ground floor and underground car park.

We began by cutting out the existing sealant and repairing compromised joints using Sikadur-31 CF to ensure the new sealant would meet warranty standards.

The joints were then meticulously resealed with Sikaflex® PRO-3 Purform, supported by 3N primer and PEF rod for enhanced durability. Our work covered critical areas, including the polished concrete floors, columns, and floor-to-wall joints, providing long-lasting protection and maintaining the facility's structural integrity and aesthetic appeal.

RNZAF Base Ohakea

RNZAF Base Ohakea

At RNZAF Base Ohakea, our team was entrusted with the precise application of sealant to aluminium cladding panels across multiple elevations and structural elements.

Using DOWSIL™ 688, we expertly sealed joints on various sections, including vertical and horizontal joints on the Southeast Elevation, soffits, roof access stairs, and canopy fascia.

Our meticulous work extended to critical areas like the DB Room, and numerous other structural components, ensuring the aluminium cladding was effectively sealed for long-lasting durability and weather resistance.
