McElligotts recently completed an extensive project at RAAF Base Darwin, contributing to the construction of a vital fuel storage facility. This work was carried out in partnership with NACAP as part of a broader initiative to enhance operational capabilities under the United States Force Posture Initiatives infrastructure program. The project involved two distinct phases, both requiring expert application of industrial coatings in Darwin’s challenging climate conditions.
The first phase focused on preparing the foundation for two new fuel tanks. The concrete base was track blasted to create an optimal surface profile, ensuring strong adhesion for the protective coatings. This process removed contaminants and inconsistencies, providing a clean, stable foundation for the subsequent coatings. Given the extreme daytime temperatures in Darwin, all work was conducted at night when conditions were more suitable for application and curing.
After a brief intermission, McElligotts returned to commence the second stage of the project. Two newly installed tanks required full scaffolding and containment before undergoing abrasive blasting. This step was crucial in achieving the necessary surface preparation, removing any impurities that could compromise the longevity and performance of the coatings.
An epoxy zinc primer was then applied to the exterior of the tanks. This type of coating plays a crucial role in corrosion prevention, forming a durable barrier that protects the metal substrate from environmental exposure. The use of epoxy zinc coatings is particularly beneficial in industrial settings, where exposure to moisture and harsh conditions is inevitable. It acts as a sacrificial layer, preventing rust and degradation over time. Following this, a high-build epoxy coating was applied to provide additional protection and ensure long-term durability.
This project marked a significant milestone for McElligotts, as it was the first time the team utilised heat shrink containment on site. While the team has extensive experience using other containment sheeting on previous projects, this new approach demonstrated our ability to adapt and expand service offerings based on project requirements. Heat shrink containment provided a secure environment, minimising external contamination and improving coating application efficiency.
Through our expertise in industrial coatings, McElligotts played an essential role in ensuring the longevity and structural integrity of these vital fuel storage tanks. Our ability to execute high-quality work in demanding environments reinforces our position as a leader in protective coatings solutions.
