Planning Your Retaining Wall Installation
Proper planning is crucial for a successful installation. Follow these steps:
Step 1: Assess the Area
Evaluate the area where you plan to install the retaining wall. Consider factors such as slope, drainage, and the purpose of the wall.
Step 2: Determine Wall Height and Length
Decide how high and long you want your retaining wall to be. Keep in mind that taller walls may require additional engineering considerations and permits.
Step 3: Mark the Layout
Use stakes and string lines to outline the wall's position. Ensure that the layout is level and follows the desired design.
Step-by-Step Belgard Retaining Wall Installation
Once you have planned your project, it's time to start the installation. Follow these steps:
Step 1: Excavate the Area
Begin by excavating the area to a depth of about 6-8 inches. This will allow for a solid base of gravel and the wall blocks.
Step 2: Create a Level Base
Add a 4-6 inch layer of crushed stone or gravel to the excavated area. Use a compactor or tamper to compact the base thoroughly. Ensure the surface is level by checking with a level tool.
Step 3: Install the First Course of Blocks
Start placing the first course of Belgard blocks on the prepared base. Use a rubber mallet to tap them into place, ensuring they are level and aligned. This layer is critical, as it provides the foundation for the entire wall.
Step 4: Add Drainage (if Needed)
If your wall will retain a significant amount of soil, consider installing a drainage pipe behind the first course. This will help manage water pressure and prevent damage.
Step 5: Build Additional Courses
Continue stacking the blocks, staggering the joints between courses for stability. Each course should be slightly set back (about 1 inch) from the course below to create a sufficient slope.
Step 6: Backfill as You Go
As you build, backfill behind the wall with gravel or crushed stone to provide additional support and drainage. Ensure that the backfill is compacted to avoid settling.
Step 7: Finish the Top Course
Once you reach the desired height, install the final course of blocks. You can cap the wall with special cap blocks for a finished look.
Post-Installation Care and Maintenance
After your Belgard retaining wall is installed, proper care and maintenance are essential to ensure its longevity.
Regular Inspections
Inspect the wall regularly for signs of shifting or settling. Address any issues promptly to prevent further damage.
Weed and Debris Control
Keep the area around the wall clear of weeds and debris. This will help maintain proper drainage and prevent erosion.
Drainage Maintenance
If your wall includes drainage systems, ensure they are clear of blockages to allow for proper water flow.
