Flat Jack

The Flat Jack is a precision instrument designed for measuring structural loads and soil pressures in tunnels, retaining walls, dams, and other civil engineering projects. Using robust hydraulic technology, it provides reliable, repeatable, and drift-free measurements, making it ideal for long-term geotechnical monitoring and structural assessment.

This device works by inserting a flat hydraulic jack into a pre-cut slot in structural elements or soil layers. As pressure is applied or changes occur, the jack translates these forces into measurable data, which can be recorded and analyzed for engineering decisions. Its simple yet effective design ensures stable performance under harsh field conditions, including vibration, moisture, and temperature variations.

Engineers rely on the Flat Jack for monitoring load distribution, detecting stress changes, and evaluating the structural behavior of critical infrastructure. Integration with dataloggers or manual recording systems allows flexible monitoring approaches while reducing the need for frequent inspections.

The Flat Jack delivers engineers a dependable, precise, and durable solution for monitoring structural loads and soil pressures in critical infrastructure projects.
