A 7 strand galvanized steel loop at top center

specialty blocks for tighter radii
h Standard grade:One full lone side face free of
large blemishes,shade of concrete may vary
Utility grade:All surfaces may contain large
blemishes, honeycomb, chips-concrete may be
colored.
Architectural:Specialized pattern such as
quarrystone or cutstone
Blocks are manufactured using surplus concrete
and strength levels will vary.Guaranteed
strength can be obtained with Schmidt Hammer
Test or fresh concrete for additional charges.

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 required.
2. Coulomb (sliding wedge)or Rankine (earth pressure)analysis can be used
to determine adequate resistance to sliding and overturning of the blocks.
INSIDE ANGLE (GRAVITY WALL) 90°CORNER -NO BATIER (MSE WALl:)
4.Consider additional transient or permanent loads behind the wall.
3.Analysis must include additional loading effects of sloping backfill.
5.Bearing capacity of foundations including additional loads from backfill on
wall should be considered.
6. Prevent the migration of fines through the wall with use of filter material.
7. Consider overall stability of retaining wall,backfill and subgrade.

Note: No construction should be undertaken without professionally engineered
specifications for the site and issuance of proper permits
