Understanding Retaining Walls: Function, Types, and Construction

Here's a detailed description of the image: **Setting:** The image depicts a well-maintained garden in what appears to be a residential area. It showcases elements of landscaping with stone retaining walls, green grass, and various plants and trees. **Foreground:** A curved retaining wall constructed of tan-colored stones dominates the foreground. The stones are arranged in a slightly staggered pattern to create a textured appearance. Atop this wall, there's an array of flowers and plants, including: * Yellow daffodils with green foliage. * A carpet of small blue flowers. * Green ground cover. **Midground:** * To the right of the retaining wall, a neatly trimmed lawn of green grass extends into the midground. * A thin, light-colored tree stands near the wall. * Beyond the flowers, there are taller, neatly trimmed evergreen shrubs, creating a sense of depth. * Another stone retaining wall is slightly further back on the right side of the image. **Background:** * A light blue house is partially visible in the background. * There are more trees and bushes behind the house, forming a dense green backdrop. **Overall Impression:** The image conveys a sense of order, tranquility, and natural beauty. The colors are vibrant, with the greens of the grass and plants contrasting against the earthy tones of the stone walls. The well-kept nature of the garden suggests careful attention to landscaping.

Retaining walls are an integral part of residential and commercial landscaping designs. They provide structural support enhance the aesthetic appeal and make uneven or sloping terrains accessible. Knowing their types, and how they are constructed is a must, whether it is a small backyard oasis or a large commercial property. Let’s dive into the basics, their types, and considerations when building one.

What Are Retaining Walls?

Retaining walls are designed to hold back the earth and prevent sliding down on the sloping earth. They would be ideal for properties characterized by uneven surfaces as they may create level space for gardening or patios. In addition, they give a property enhanced aesthetic value besides functionality. Here, they can present a design where the architectural features are complemented.

The image features a tiered retaining wall constructed from gray concrete blocks, positioned against a backdrop of small, dark gray gravel or stones. The wall is built on a slight curve, with each tier stepping back from the one below it. This design creates a layered effect and helps to support the gravel behind the wall. The concrete blocks are uniformly shaped, and the lines where they meet are distinct and consistent throughout the structure. The gravel is dense and evenly distributed, providing a contrast in texture to the smooth concrete. The lighting in the image is uneven, casting shadows on the wall and adding depth to the scene. The overall composition of the image suggests a sturdy and well-constructed landscape feature.

The retained soil exerts gravity and lateral pressure, making a retention wall be designed and constructed correctly. It is at this point that an excellent construction company in St. Louis, such as Brico, proves very handy.

Functions of Retaining Walls

They perform a few crucial functions. Some of the functions include:

  • Erosion Control: They control soil erosion on sloping land. They make the ground stable.
  • Water Management: They can be designed in such a manner that the flow of water can be changed; thus, the risk of waterlogging and degradation of soil is prevented.
  • Optimization of Space: The sloping ground can be levelled, and its space usage can be optimized for functional or aesthetic purposes.
  • Structural Support: They support where they are needed to prevent slanting off of soil or landslides in steeper gradients of a piece of property.
  • Aesthetic Appeal: With the right materials and design, they can change the outlook of outdoor spaces hence making them appealing to the eye.

Types of Retaining Walls

There are a large number of varieties. Each kind falls into one or more classifications in terms of advantage and construction. A wall usually depends upon parameters such as the steepness of the slope, the nature of the soil, or preferences for beauty. 

The following represents a list of the most common types.

Here is a description of the image: The image is a diagram illustrating different types of retaining walls. It is a technical drawing with simple illustrations and labels. The diagram is titled "DIFFERENT TYPES OF RETAINING WALL" at the top. It's divided into four sections, each showing a different type of retaining wall: 1. **Gravity Wall:** This shows a trapezoidal wall, thicker at the base and tapering towards the top. Arrows illustrate forces acting on it. 2. **Piling Wall:** This shows a thin, vertical wall supported by piles driven into the ground. Arrows indicate the forces at play. 3. **Cantilever Wall:** This depicts an "L" shaped wall where the vertical part retains the earth and is supported by a horizontal base. Arrows show the forces. 4. **Anchored Wall:** This shows a vertical wall supported by anchors or tiebacks that extend into the retained soil. The anchors are shown as lines with arrowheads. Each wall type has a label under it: "GRAVITY," "PILING," "CANTILEVER," and "ANCHORED." The diagram is clean and simple, designed to visually explain the differences between the various types of retaining walls. The walls themselves are red and there are gray lines indicating the soil behind the walls. The lines and text are dark.
  1. Gravity retaining walls:

They are resistant to soil pressure on the opposite side due to self-weight. It mainly depends upon the construction materials of heavy walls like stones, concrete, and bricks. They suit for the small height and medium size of the wall, available in classical robust design.

  1. Cantilevered Retaining Walls

 Reinforced concrete structures include an L-shaped base and thin stem with a base slab, in which the extension extends under the soil to stabilize further. Cantilevered walls, which can absorb enormous loads, are quite effective for higher walls.

  1. Sheet Pile Retaining Walls

Sheet pile walls consist of thin sheets of steel, wood, or vinyl being driven into the ground. They have also been deemed proper for soft soil regions and space-consuming regions. They are not considered decorative in their aspect; rather, they are less costly, which renders them appropriate for certain applications.

  1. Anchored Retaining Walls

In this type, they are held to the surrounding soil or rock with cables or rods. They are used where immense pressure is involved or at locations where the load has to be carried by a lot of force. They can merge with any other types of retaining walls for extra strength.

  1. Segmental Retaining Walls

This type is interlocking concrete blocks. It is a favorite owing to its flexibility, durability, and aesthetic appeal. SRWs could be a great DIY or professional installation option.

The image showcases a beautifully landscaped outdoor living space. The focal point is a multi-tiered retaining wall constructed from brown textured stone blocks, topped with a smooth, light beige cap that serves as a border. The wall gracefully curves, creating visual interest and defining different levels of the outdoor area. On the lower tier, a bed of small, green shrubs lines the wall, adding a touch of nature and softening the stone structure. Above the wall, a paved patio area is visible, featuring a fire pit in the center and red Adirondack chairs in the background, suggesting a cozy and inviting gathering spot. A black lounge chair is also visible behind the top of the wall. The surrounding landscape is lush and green, with various plants and trees providing a natural backdrop. The overall impression is one of a well-designed and inviting outdoor space, perfect for relaxation and entertaining.
  1. Gabion retaining walls

Made of wire mesh that is filled with rocks or other materials. They are environment-friendly, and economical, and offer a natural look of the wilderness. They are perfect for places where erosion occurs or tends to flood.

The image shows a retaining wall constructed of gabions, which are wire mesh baskets filled with rocks. The wall is stepped, with multiple tiers running along the edge of a road. The road has a white line marking the lane, and beyond the road and the base of the wall, there's a thin strip of reddish-brown soil or mulch. The gabions are filled with rocks that appear to be a mix of sizes and colors, predominantly earthy tones. The wire mesh is visible, creating a grid-like pattern across the face of the wall. Above the wall, there is a slope covered with greenery, suggesting natural vegetation and possibly trees. In the distance, there is a tunnel entrance with vehicles visible inside, and atop the slope, there appears to be a building or house partially obscured by the trees. The sky is clear and blue, indicating a sunny day. The composition of the image suggests that the gabion wall is serving to stabilize the slope next to the road.

Things to Consider When Constructing a Retaining Wall

There are a few things that have to be considered in the construction 

of it to be effective and durable. Some of them include:

  1. Type of soil

The design and construction may depend on the type of soil on your land. For example, clay retains more water than any other type and exerts pressure; for such a soil condition, much stronger walls are necessary.

  1. Drainage

The water accumulation at the back of the retaining wall is crucial. As it adds more pressure to it and can break easily. Thus, weep holes or drainage are added to the design to reduce its risk.

  1. Height

The design will depend on how tall it would be since higher walls will have stronger methods of building and using sturdier materials to stand more pressure due to added stress on it.

  1. Building Codes

Some higher walls fall under permit and local building codes. Companies that have professionalism like Brico would ensure that all regulation requirements are met in St. Louis.

  1. Material Choice

Materials will be those which define longevity, beauty, and cost. Major types of materials include natural stone, concrete, brick, and timber. This depends on which will make them look beautiful and strong.

Here is a description of the image: The image is a collage presenting various materials used for constructing retaining walls. It includes five distinct images arranged in a way that creates a guide. Starting from the top left, there is a retaining wall built with a flat, horizontally stacked stone pattern, with green bushes planted atop it. Moving to the right, the next image shows a retaining wall made of layered stone, holding back dark soil with sparse green plants and a wooden fence in the background. The top right image displays two retaining walls constructed with large, irregularly shaped rocks held in metal cages, with greenery behind them. At the bottom of the collage, a large, stylish retaining wall made of light-colored, rectangular blocks is visible, providing a multi-tiered landscape near a modern building. The text "Materials to use while Constructing Retaining Wall" is superimposed over a dark gray background, indicating the theme of the image.

Construction Process

Steps to be taken in the construction are the following steps:

  1. Plan and Design
  • Know the topography of the site and the conditions of the soils.
  • Kind of wall and materials to be used
  • Draw a plan on the design, also drainage
  1. Excavation and Foundation
  • Dig the area for the construction of the wall.
  • Good base using compacted gravel or concrete.
  1. Wall Construction
  • Build up layers of the wall, every layer must be level and aligned.
  • Add reinforcement if necessary and can be geogrid or rebar
  1. Installation of Drainage
  • Installation of pipes or weep holes if there is going to be some water gathering on the backside of the wall
  1. Backfilling and Compaction
  • Position some gravel or the choicest materials to fill up the area at the back of the wall
  • Soil stability
  1. Finishing Works
  • Give aesthetics to this one as finishing works such as paving, lightening, and planting.
Here is a description of the image: The image presents a diagram illustrating the construction of a mortar-less wall, highlighting several key steps and considerations. In the diagram, a section of earth is cut away to reveal the wall's foundation and construction. The wall is made of irregularly shaped stones that fit together without mortar. The image emphasizes that the mortar-less method is best for walls higher than 3 feet. The bottom layer of the wall is composed of larger, "heaviest" stones, as indicated by a note: "Keep your fattest, heaviest stones for first course & capstones." Below this, the foundation is constructed within a trench described as "12" deep with width 1/3 the wall's height." The diagram also emphasizes stability, indicating that the inclusion of "deadmen" is important for that purpose. On the back side of the wall, it is written to "Check level, backfill, & tamp down after each course." The term "Stagger Joints" is marked on the diagram which implies that stones are arranged to prevent continuous vertical joints for improved strength. The surrounding landscape includes soil, with some vegetation, possibly trees or bushes, in the background.
