Why Retaining Walls Fail

Most failed walls have the same problems. The failure begins with a Bad base layer. Incorrect drainage worsens this problem over time.

We fix these issues with the following solutions.

• Compacted stone base. Reduces the chances of base settling.
• Buried first block layer. This provides a solid foundation locking the wall in place,
• Clean drainage rock & commercial grade drainage pipe.
• Geogrid layers on walls over 48″ to lock the blocks into the ground
• Correct setback. The Belgard Diamond Pro 9D Block is engineered with this in mind
