EJ Systems Australia is a specialist contractor focused on the supply and installation of engineered expansion joint, fire seal and waterproofing systems for commercial, retail, health and infrastructure projects.

Our core expertise is delivering technically correct, compliant joint systems that accommodate structural movement while maintaining fire separation, watertightness and public safety. We work closely with builders, engineers and architects to ensure each system is installed in accordance with tested performance requirements, NCC compliance and project-specific design criteria.

Because EJ Systems installs these systems, we maintain detailed knowledge of the as-built configurations, movement allowances, fire seal layouts and waterproofing interfaces across each project. This allows us to also provide specialist inspection, servicing and lifecycle maintenance programs, ensuring systems continue to perform as designed long after practical completion.

From new installations to long-term asset care, EJ Systems delivers technically sound solutions that protect buildings, reduce risk and support compliance for the life of the structure.
