The Battle
with the Bulge
Look at this
beautiful lakefront property in northern British Columbia. It’s a secluded
cabin with the added “curb appeal” of a 12’ (3.7 m for our metric friends) tall
Allan Block wall. Like so many of us, the owner of this cabin wanted to address
a relatively large grade change in his backyard and gain as much usable space
as possible. What was his first step? He called a trusted local contractor who
had been in business for over fifty years.


- The high water line was not considered at the base
- No thought was given to water management
- No wall rock
- No drain pipe
- Poor clay native soils were used as backfill
- No geogrid was used
- No soil compaction performed
Sufficed to
say the homeowner was dissatisfied with his retaining wall. The contractor
readily admitted his mistakes and offered to correct them. We provided him with
our Best Practices
document and our Commercial Installation Manual. The wall is scheduled to be rebuilt
in the Spring of 2017. Hopefully, this time it’s built correctly. Time will
tell.
