With increasing demand for property and land in our cities, many sites once considered uneconomical for development are being re-contoured to produce functional building sites.

There are numerous options available for temporary and permanent retaining structures required to facilitate construction or prevent subsidence. ACH Consulting Engineers has a number of specialists in the design of earth retaining structures.

Selecting an appropriate solution for any particular retaining situation requires experience. Our retaining experts take this experience, combined with a commitment to keeping abreast of the changes to regulations and best practice, to provide high quality solutions for our clients. We have developed and maintained a proficiency in the design of segmental reinforced earth walls, use of combined steel and timber sections and precast concrete elements. Our design team also provides professional advice to property owners, or insurance companies, in cases where existing retaining walls have required strengthening or replacement.
