Our Gravity walls are a cost effective retaining wall solution that are constructed to ensure longevity.
A gravity retaining wall is one designed and constructed to rely on its own weight to stand up.
Another of the techniques often employed by GSS on behalf of our clients, the walls are very cost effective and most often used in areas where there are no concerns with overall ground stability. One of the most common types of gravity walls is the crib wall, a simple and cost effective technique often used for highway cuttings and similar slopes. Crib walls are constructed from interlocking precast concrete components, filled with free draining material and earth backfill.
While the process appears deceptively simple, it is critical that the wall is designed and constructed properly to ensure its structural integrity and longevity.
To make sure that you get the right type of retaining wall for the situation, it’s important to make sure that you have an accurate understanding of the project’s conditions and requirements. Every retaining wall needs to be specifically engineered to withstand the pressure from the soils and other sedimentary loads exerting pressure from behind, and sometimes from above. The design process for each gravity needs to take into account a number of factors including overturning, sliding and bearing forces.
There are a number of different types of gravity walls and the kind of retaining system that best suits your needs can largely depend on your project’s environment and structural requirements.
Cantilever retaining walls are typically built from reinforced concrete. They are designed with a relatively thin stem and a thicker base slab and can often be pre-cast or cast on site.
