Types of Retaining Walls
Retaining walls support or restrain soil that might otherwise erode. These structures allow you to shape your landscape between different elevations, making your garden more functional. Retaining wall installers in the Bay Area have many different types of retaining walls that can be used to control the erosion and drainage in your yard. You should always have professionals design and engineer retaining walls because they need to be able to handle the pressure of the soil behind them.
Gravity Retaining Walls
A gravity retaining wall uses the weight of its material to hold the soil in place. You can use a variety of materials in these types of retaining walls in the Bay Area, but these walls can’t get too big. They may also need a cement foundation to hold the materials in place.
Reinforced Retaining Wall
A reinforced retaining wall adds stability to the wall when the height of the wall is too high for a gravity wall. The soil is stabilized through different methods to keep the wall from collapsing from the strength of the soil.
Cantilevered Retaining Wall
Cantilevered retaining walls are the most common type of retaining walls. The wall is attached to a foundation, in an “L-shape” that prevents the wall from tipping over. These walls need to be engineered based on the amount of soil that they are holding back.
Sheet Piling Retaining Wall
Long poles or sheets of vinyl or other material are placed deep in the soil to keep it from eroding. These types of retaining walls are quite useful when space is an issue but work more effectively in softer soil. Again, engineering is key to their functionality. Larger walls often need additional reinforcement.
Anchored Retaining Wall
Anchored retaining walls aren’t constructed differently from the styles mentioned above, but what makes them different is the additional strength they get from cables or other types of stays that are anchored into the rock. If a retaining wall requires additional strength, an anchor provide extra support without completely replacing the wall.
