Type Of Retaining Wall

Let’s look at the 5 most common types of retaining walls:

Read more about each below


Poured Concrete

Poured concrete: A concrete retaining wall is the process of creating a block wall or a supporting structure for outdoor space by pouring fresh concrete into a form work or casting mold. This method provides high strength and durability for the structure, since concrete completely fills the entire space and hardens, creating a single mass.

Poured Concrete Wall, Advantages:

Strength: Concrete pouring provides a high-strength structure that can withstand significant loads.

Uniformity: Concrete is poured into a mold or form work and creates a uniform structure with no joints or seams, which increases its stability.

Airtightness: Poured concrete provides an airtight structure, preventing the penetration of moisture and other harmful substances.

Design flexibility: Concrete pours allow the creation of various shapes and sizes of retaining structures, as well as the integration of architectural elements such as windows, doors timber walls, and decorative patterns.

Concrete Blocks (Concrete Blocks)

Concrete blocks, also known as bricks or cellular interlocking concrete blocks or cinder blocks, are another common material for retaining structures. They are made from remolded concrete and have a hollow structure, making them lightweight and easy to manipulate.

Advantages Of Using Concrete Blocks Include:

Ease of installation: Concrete blocks can be in stacked shapes easily joined together using adhesive mortars or special fixing elements to simplify the construction process.

Insulating properties: Blocks made of pure, concrete walls have good heat and sound insulation, which contributes to the creation of a comfortable microclimate in the room.

Cost-effective: Concrete blocks are a relatively inexpensive material, which makes them attractive from an economic point of view.

Fire resistance: Concrete is a non-combustible material, so concrete blocks have high fire resistance.

Brick Wall

A brick wall is a type of structure that uses brick elements to hold and support the ground or other loads. It is widely used in the construction of walls and support structures. A brick wall can be constructed from different types of bricks, such as burnt brick, sand-lime brick, or cinder block.

The bricks can be joined together using a special cement or lime mortar called masonry mortar. These structures provide stability and strength, making them an ideal choice for enclosing slopes or creating foundations. They have good resistance to moisture and weather conditions.

Wooden Retaining Wall

A wooden retaining wall is a type of structure that uses wooden elements to support and hold earth or other loads. It is widely used in the construction of walls, fences, terraces and other support structures.

Wood retaining walls typically use wood beams, posts, or piles that are installed vertically or horizontally to create support and rigidity. To improve stability and strength, wood retaining wall members can be connected together using special fasteners such as bolts, brackets, or nails.

The advantages of timber retaining walls and structures include their natural beauty, material availability, and excellent construction properties. Wood is a lightweight and strong material that provides sufficient strength and stability to the structure.


Boulder retaining walls are structures consisting of large stones or boulders that serve to stabilize slopes, river banks, or lake banks. These walls prevent soil washout or slope collapse. Boulder retaining walls are usually built in the form of a slope, with stones stacked in regular rows.

Cement or other bonding material may be used between the stones. In some cases, these walls may be supplemented with a drainage system to provide stability to crushed stone walls and prevent moisture from accumulating behind the wall, which could lead to further deterioration.


A gabion is a structure made of a wire mesh that is filled with stones or other materials. It is used to reinforce and support various structures, including walls. Gabion retaining walls have several advantages: High strength: due to the use of stones as filler, gabion walls have great mechanical strength and resistance to loads.

They are able to withstand soil pressure, support slopes, and prevent landslides. Durability: gabion walls are made of pebbles, stones, or other materials that are not subject to corrosion and retain their properties for a long time.

Aesthetic appearance: due to the presence of stones inside the mesh, gabion walls have a natural appearance, which allows them to blend well into natural look of the surrounding landscape environment. Eco-friendly: gabions are often used in the environment as they create sustainable, eco-friendly structures that allow you to interact with nature without negative effects.

Gabion walls are widely used in construction to create support and backing structures, as well as to protect against soil erosion and demolition. They find application in both individual and industrial construction, as well as landscape maintenance costs as in landscaping company landscape design.
