Concrete Retaining Wall Thickness Rule Of Thumb

There are many types of retaining walls.

Concrete retaining wall thickness rule of thumb.

By thumb rule method. Retaining walls must be stable and the usual rule of thumb for small height brick retaining walls is for the height to lie between 2 and 4 times the wall thickness. Gabions are baskets filled with rocks. The wall to the right is 800mm wide and 1600mm high.

Retaining walls up to 1m high 2. Approximate thickness h 10 14 2. This was often quite adequate for garden walls but due to the varying nature of sub soils topography of land and surrounding environment this does not always work. Civilsolution foundation in this video we learn that how to design wall footings like width of foundation depth of foundation depth of concrete block etc.

Wall w heavy reinforcing concrete structural element structural depth l 30 to l 40 l 40 to l 50. There are some basic rules of thumb for foundation wall thickness and these are outlined in many modern building codes. As a rule of thumb this method works and will give a factor of safety in excess of 1 5 in most cases. However when the wall is located adjacent to other structures the failure of the wall usually results in distress to the adjacent structure whether it is a pool a patio or a building structure.

In open areas a retaining wall failure may go unnoticed or may not be a concern to the owner. Stability can be checked by applying the middle third rule. Design rules of thumb in the early stages of a project we are often. For cantilever sheet pile retaining walls the penetration below the bottom should equal approximately the unsupported height above.

Rule of thumb is 24 to 36 times the thickness gives the spacing in mm inches. These rock baskets can be used to construct retaining walls. Earth retaining structures are an essential part of civil engineering. Gravity walls are made of rock concrete and masonry.

Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well. As a general rule you can build economical gravity retaining walls from 600mm. In the case of gravity walls the pure weight of the retaining wall holds the soil.
