Deep Excavation

Deep excavation design and construction requires sophisticated engineering expertise to achieve safe and economical solutions. It also requires understanding of geological challenges and the many design methods available today.

Our experienced geotechnical engineers specialise in complex soil structure interactions. Knowledge of these supports engineering geology and other specialist fields related to deep excavations.

We provide invaluable advice covering proven empirical solutions and the latest dynamic numerical methods. Our services range from specialist analysis to detailed design, giving you a cost-effective and appropriate solution for your structure.
