Step 5
- Augered hole is backfilled and compacted
and the sod is replaced
(Figure 4.2.5.a5)
.
Step 6
- Anchors can be tightened at specified
intervals to straighten wall over time, if desired
(Figure 4.2.5.a6)
. Tightening of the anchors
generally occurs during drier seasons of the
year when there is less pressure on the wall and
shrinkage gaps may have formed between the
wall and the soil.
4.2.5.1 Solutions for Extreme Wall
Problems
An owner may wish to have a basement wall or
retaining wall straightened immediately, rather
than follow the periodic tightening procedure.
The soil behind the wall must then be completely
removed down to the footing. With the soil load
temporarily removed, thewall can be straightened.
The Geo-Lock system then stabilizes the wall
against future inward movement. See
Figures
4.2.5.1.a1 and
4.2.5.1.a2
.
Block walls in later stages of distress may
show inward shear movement at the bottom
of the wall. The bottom row of the block wall is
restrained by the basement floor slab while the
wall section above continues to deflect inward.
