Retaining walls can be used for various purposes, from protecting agricultural land to defining commercial property lines. They provide structural stability by preventing soil erosion in areas that may experience high winds or rainstorms.
The best way to select the correct type of retaining wall is by considering a list of factors, including environmental concerns, construction design, and site constraints. You should also take aesthetics into account when choosing which one will suit your needs aesthetically as well. Listed below are the different types of retaining walls, with their distinct advantages and disadvantages.
Gabions
Gabions are retaining wall systems that consist of baskets filled with rocks, which are then welded or wired together. They can be used in various settings, including on slopes and around bridges. Gabions are an excellent choice for areas that experience heavy rainfall or severe weather conditions because they can withstand a great deal of water and wind damage.
Crib walls
Crib walls are retaining walls made up of interlocking timbers or logs. They are often used in agricultural settings to protect against soil erosion. Crib walls can also be used in commercial construction projects, such as office buildings or parking garages. Because they are made from timbers, crib walls are a good choice for areas susceptible to fire damage.
Sheet pile walls
Sheet pile walls are retaining walls that consist of interlocking sheets of metal or wood. They are often used in coastal construction projects, such as sea walls or levees. Sheet pile walls can also be used in river or stream construction projects to prevent erosion.
Articulated block walls
Articulated block walls are retaining walls made up of interlocking blocks. The blocks are usually made of concrete and are designed to fit together snugly without the need for mortar or other adhesives. The advantages of articulated block walls are that they can be built quickly and easily and require little maintenance over time.
Mechanically stabilised rock walls
Mechanically stabilised rock walls are retaining walls anchored into the ground at one end and extending outwards from the anchor point. This ensures that the barrier is strong enough to resist the force of the soil or rock behind it. They are typically used to support soil or rock slopes to prevent erosion or instability. Mechanically stabilised rock walls can be made from various materials, including concrete, stone, and timber. In some cases, a geotextile fabric may be used to reinforce the wall further.
Buttress walls
A buttress wall is a retaining wall reinforced with horizontal beams or planks. The beam may be attached to the wall itself or set into the ground behind it. The purpose of the buttress is to provide additional support for the wall, which can help to prevent it from collapsing. Buttress walls are often used in areas where the soil is particularly unstable or where there is a risk of landslides.
Final thoughts
As you can see, there are various types of retaining walls. When selecting the right one for your needs, be sure to consider the factors listed above. Then, with a little bit of research, you should be able to find the perfect retaining wall for your commercial construction project.
