1. Always use free draining backfill to allow drainage. Where high ground water
conditions occur in the native ground, chimney or blanket drains may be require
2. Coulomb (sliding wedge) or Rankine (earth pressure) analysis can be used
to determine adequate resistance to sliding and overturning of the blocks.

4. Consider additional translent or permanent toads behind the wall.
5. Bearing capacity of foundations including additional Ioads from backfllI on
wall should be considered.
6. Prevent the migration of fines through the waft with use of filter material.
7. Consider overall stability of retaining wall, backfiII and subgrade.
Note: No construction should be undertaken without professionally engineered
specifications for the site and issuance of proper permits
