Types of Retaining Walls: A Comprehensive Guide

April 20, 2023

Introduction

Retaining walls are structures that are built to stabilize soil and prevent erosion. These walls are designed to withstand the pressure of soil and water, and they can be constructed using a variety of materials. In this comprehensive guide, we will take a closer look at the different types of retaining walls, their uses, and their advantages.

Gravity Retaining Walls

One of the most common types of retaining walls is the gravity retaining wall. It is typically composed of concrete blocks or other heavy materials that are designed to resist the pressure of soil and prevent it from slipping or sliding. Gravity walls are typically used for areas where the slope is less than ten degrees.

Sheet Piling Retaining Walls

Sheet piling retaining walls are made of steel, vinyl, or wood planks that are pressed tightly into the ground. These walls are typically used for soil retention in areas where the ground is soft or unstable.

Brick Masonry Retaining Walls

Brick masonry retaining walls are typically made of bricks that are stacked together and held in place with mortar. These walls are a popular choice for residential applications due to their durability, versatility, and aesthetics.

Concrete Block Retaining Walls

Concrete block retaining walls are made of precast concrete blocks that are stacked together and held in place with mortar. They are typically used for retaining walls that require a high degree of stability and strength.

Timber Retaining Walls

Timber retaining walls are typically made of wood boards that are held together with steel rods or wooden pegs. These walls are commonly used in residential settings due to their low cost and easy installation.
