Our Retaining & Seat Wall Block Installation Process

Built for Strength, Stability, and Long‑Term Performance

Retaining and seat walls must withstand soil pressure, weather changes, and daily use. That’s why every wall we build follows a reinforced, engineered installation process designed to prevent shifting, leaning, and settling. As a Unilock Authorized Contractor through our sister company Beautiful Stones, we use industry‑leading materials and proven construction methods to ensure your wall remains strong, level, and beautiful for years to come.

Site Evaluation & Wall Design
We assess soil conditions, drainage needs, elevation changes, and load requirements to ensure your wall is designed for optimal height, length, and structural support.
Excavation & Base Preparation
Our team excavates to the required depth and installs a compacted gravel base that meets Unilock specifications, preventing wall movement and ensuring long-term stability.
Leveling & First Course Installation
The first course of block is installed with precision, establishing the strength, alignment, and stability of the entire wall.
Block Installation & Reinforcement
Each course is stacked with proper setback and alignment, incorporating geogrid reinforcement as needed to enhance structural strength.
Drainage System Installation
We install drainage stone and perforated drain tile behind the wall to relieve hydrostatic pressure, a critical step for long-lasting performance.
Backfilling & Compaction
As the wall is built, we backfill in layers and compact the material to ensure stability and prevent future settling.

Retaining & Seat Wall Block Repair & Maintenance

Restore Strength, Stability, and Long‑Term Performance

Retaining and seat walls naturally experience stress from soil pressure, drainage issues, and seasonal freeze‑thaw cycles. Over time, this can lead to leaning, shifting, settling, or loose caps. Our repair and maintenance services restore the structural integrity, appearance, and safety of your wall so it continues performing as intended.



Our retaining and seat wall repair services include:

  • Straightening and rebuilding leaning or bulging retaining walls
  • Resetting loose or shifted wall blocks
  • Replacing cracked, chipped, or damaged units
  • Improving drainage with stone backfill and perforated drain tile
  • Resetting or replacing loose wall caps
  • Reinforcing walls with proper setback and geogrid (when needed)
  • Correcting settling caused by poor base preparation or water issues


Whether your wall needs minor adjustments or a full structural rebuild, we ensure it remains safe, stable, and visually consistent with your outdoor space.
