Cantilevered Walls
Cantilever retaining walls use strengthened concrete with a base piece and a slim stem to utilize take advantage of for retaining. The base framework will be fixed to a piece framework and also will certainly have support in the form of an “L.” Because of the hefty lots of dirt that is above the base and this “L” structure, the piece will certainly not have the ability to tip ahead. Backfill can also support the wall and avoid rescinding or sliding.
Due to the heavy amount of dirt that is maintained by a cantilever retaining wall, it’s essential that it is well-engineered in order to stand the test of time.
Cantilever retaining wall surfaces are occasionally thought about the most common sort of a retaining wall, and also they are specifically preferred for commercial retaining because of the amount of dirt it can keep.
In order to include added strength and also boost the design of a basic cantilever retaining wall, there are various other components that can strengthen the cantilever retaining wall, including counterfort or buttressed keeping wall. This is typically made use of when retaining wall surfaces need to be taller.
Calgary Retaining Walls are specialists in the style as well as construction of cantilevered retaining walls, which implies you will have peace of mind that the engineering will be ideal for optimum toughness as well as safety with time.
Cantilever retaining walls are constructed of reinforced concrete. They consist of a relatively thin stem and a base slab. The base is also divided into two parts, the heel and toe. The heel is the part of the base under the backfill. The toe is the other part of the base.
Use much less concrete than monolithic gravity walls, but require more design and careful construction. Generally economical up to about 25 ft. in height. Can be precast in a factory or formed on site.
Cantilever walls are used to hold back a large amount of soil. They are made with steel-reinforced concrete that rest on slab foundation. Cantilever walls convert horizontal pressures from the soil to vertical pressures on the ground. A cantilever retaining wall uses a T or L shaped footing – or poles – which are firmly inserted into the earth to provide a strong support.

Cantilever retaining walls work on the principles of leverage and are often constructed in the shape of an inverted T with reinforced concrete or mortared masonry. Less building material is required for a cantilevered wall than a gravity wall, and they can be poured on site or manufactured at a precast concrete facility. They consist of a relatively thin stem and a base slab, which is divided into two parts: the heel and toe. The heel is the part of the base under the backfill while the toe is the other part. Rigid concrete footing is required for these walls that are usually less than 25’ high. Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage. It has much thinner stem and utilizes the weight of the backfill soil to provide most of the resistance to sliding and overturning.
Earth slopes and earth retaining structures are used to maintain two different ground surface elevations.
Function of Cantilever Retaining Wall:
To retain the soil at a slope that is greater than it would naturally assume, usually at a vertical or near vertical position.
Design Consideration
In order to calculate the pressure exerted at any point on the wall, the following must be considered:
- Height of water table
- Nature & type of soil
- Subsoil water
- ovements
- Type of wall
Material used in the construction of wall
The effect of two forms of earth pressure needs to be considered during the process of designing the retaining wall. They are:
Active earth pressure – It is the pressure that at all times are tending to move or overturn the retaining wall
Passive earth pressure – It is reactionary pressures that will react in the form of a resistance to movement of the wall.
Two Basic Form of Cantilever Wall
1) A base with a large heel so that the mass of earth above can be added to the wall for design purposes.
2) If form 1 is not practicable, a cantilever wall with a large toe must be used.
