Segmental Wall Installers are responsible for installing segmental retaining walls, which are used to retain soil and create level surfaces in various applications, including landscaping, erosion control, and infrastructure projects.

1. Site Preparation

Prepare the job site by clearing the area of debris, leveling the ground, and excavating trenches for the wall’s footings.

• Clear the area of debris, vegetation, and any obstacles.
• Level the ground to ensure a stable base for the wall.
• Excavate trenches for the wall’s footings according to the design specifications.

2. Installing the Footings

Install the wall’s footings to provide a solid base for the wall and distribute its weight evenly.

• Place crushed stone or gravel in the trenches to create a drainage layer.
• Pour concrete footings into the trenches and level them according to the design.
• Allow the footings to cure fully before continuing with the installation.

3. Assembling the Wall

Assemble the wall by stacking the segmental blocks according to the design, ensuring proper alignment and stability.
