A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil.
A basement wall is thus one kind of retaining wall. The term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures.
The most important consideration in proper design and installation of retaining walls is to recognize and counteract the tendency of the retained material to move downslope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction and the cohesive strength of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes.
We design Retaining walls of all sizes for all sorts of uses.
Adam and his team have been extremely efficient in all of our dealings from initial query to quote, scheduling times and onsite visit. The response times have been virtually immediate, and everything has been precise minimising any chance of confusion. Adam has taken phone calls and texts from our builder without hesitation and our builder was very impresssed with Adam's drawings for the removal of a structural wall in a period apartment. We couldn't recommend Adam and his team more strongly. Professional, clear, consultative, knowledgeable and gave us absolute confidence in choosing them to do our engineering component.Tanya Miller - Balaclava - VIC
