Gravity Wall Analysis. Before you analyze any retaining wall make sure you have an accurate picture of the jobsite conditions. Every retaining wall must be engineered to withstand the pressure from the soils and other loads behind and above them. Standard gravity wall analysis considers sliding, bearing and overturning forces. On sites with
Four Common Types of Rigid, Monolithic Concrete Retaining Walls. Gravity retaining walls depend on their own weight and any soil resting on the concrete in resisting lateral earth forces. They are generally economical up to 10 feet in height for cast concrete structures. Usually are sufficiently massive to be unreinforced. Monolithic cast walls are generally formed on site.
MagnumStone gravity retaining wall extenders also reduce the amount of concrete required compared to competitive solid gravity-wall. Because of the unique hollow core design and the large spaces between extenders side by side It also reduces the amount of production and transportation costs.

Rigid Gravity and Semi-Gravity Walls. Rigid gravity walls may be constructed of stone ma sonry, unreinforced concrete, or reinforced concrete. These walls can be used in both cut and fill applications. They have relatively narrow base widths. They are generally not used when deep foundations are required.
Massive Gravity Walls. Gravity walls are the earliest known retaining structures. They are built from solid concrete or rock rubble mortared together. The lateral forces from backfill is resisted by the weight of wall itself, and due to their massive nature, they develop little or no tension. Therefore, they are usually not reinforced with steel.

After rebar inspection, pour the concrete, typically a minimum of 3000 psi, into the footing trench. When casting, create a 2x4 keyway in the footing to the open non-earth side of the top leg of the dowels, separated from the dowels by 1 to 1½ inches. After the footing cures, install the wall formwork.

Cantilever walls are built of reinforced concrete and are typically composed of a horizontal footing and a vertical stem wall. The weight of the soil mass above the heel helps keep wall stable. Cantilever walls are economical for heights up to 10 m 32 feet . Typical costs in 2005 is approximately $ 80/sf.
