Construction Process of Block Retaining Wall Stairs

1. Planning and Design

• Determine the height, width, and slope of the stairs.
• Calculate the number of steps based on the rise and run.

2. Excavation

• Dig out the area for the stair foundation.
• Ensure the trench is level and deep enough for stability.

3. Base Preparation

• Lay a compacted gravel base for drainage and support.
• Add a thin layer of sand for leveling.

4. Block Installation

• Place the first row of blocks securely in the base.
• Stack additional rows to form the risers of the stairs.
• Fill the treads with compacted gravel, concrete, or pavers.

5. Backfilling and Drainage

• Add drainage pipes or gravel behind the wall to prevent water buildup.
• Backfill each step to stabilize the structure.

6. Finishing

• Install cap blocks or decorative stones on top for a polished look.
• Ensure all steps are level and safe for use.
