Our Business

We are a specialist subcontractor. Expansion joints, fire seals and waterproofing at movement interfaces, delivered for Tier-1 and Tier-2 builders across hospitals, transport, commercial towers and retail.

We handle the package end to end. Detailing and product selection during design, installation on site, and inspection and servicing after handover.

Why EJ Systems Australia?

Buildings move. Concrete shrinks, steel expands, structures settle and load shifts. The joints that absorb that movement are usually the last item on the program and the first thing to fail.

We work on those joints and nothing else. That means the detail gets resolved before it becomes a defect, the fire rating survives the movement it was designed for, and the waterproofing holds at the interfaces where most buildings let water in.

Very few contractors in Australia service expansion joints after handover. We do, which is why we know what fails and why.
