Retaining and garden walls

The wall’s length and height, the block, and what’s above it.

• Attach your Sheet so people see your sizes and the math.
• Your town is enough. Never your address; check photos for house numbers and plates.
• Is it safe? A safety question here goes to pros verified in masonry, unless you pick another trade. Only they can call it safe or unsafe.

16′ wall, 2′ tall: 58 blocks in 5 courses, the caps, 39 bags of base gravel and 64 bags of drain stone.

What people get wrong:

• A first course that isn’t level. Every error on course one repeats up the wall.
• Backfilling with the dirt you dug out. Without drainage stone, water pressure pushes the wall over within a few winters.
• Skipping compaction. Loose base settles and the wall leans.
