Water retention systems

Tetra Tech Coffey’s water retention specialists are at the forefront of geotechnical site limitations, providing solutions that reduce cost and increase safety.

Our retention system designers use their experience with soil-structure interactions, geological and hydrogeological conditions, robust calculations, and analyses to understand any project site and its history.

Our models and state-of-the-art numerical analyses use the ground’s inherent strength and stiffness characteristics to optimise support to create retention systems that are cost-effective and safe.

In soil structure interactions—such as deep, retained excavations—the construction sequence affects the stresses induced in the structure. Our team works with structural engineering and construction teams to ensure the design delivers on all project requirements.

Tetra Tech Coffey has successfully delivered several landmark water retention projects, such as the Barangaroo precinct in Sydney, Australia.
