Retaining Wall Failure: upper portion collapsed
|
When this 38-foot high retaining wall failed, Kowalski
Engineering was retained to help. Our services included
determining what caused the failure, redesigning the new retaining wall,
and reviewing the new wall's construction.
Many of the
retaining wall blocks were reused on the project - demonstrating that
these blocks are extremely durable, even after being dislodged from such
a height. You see, the large and durable block facing was not
the problem.
Retaining Wall Failure: upper portion collapsed

The problems were: the
type of soil used during construction, the spacing of the geogrids, and
(you guessed it) water. Remember this recipe for failure:
"Just Add Water".
Good design and good construction
will account for the "added water" and a retaining wall will be quite
stable. We engineered the new retaining wall and reviewed its
construction.
