I recently discovered a problem with my new deck's foundation and was hoping
you folks might have some advice on how to proceed.
Last year, I built a conventional 22' x 14' x 2'high single level deck. I
hired a local company to drill and fill with concrete the eight posts I
required for the foundation.
This year, I noticed that 5 of the 8 posts are disintegrating. The concrete
is was clearly not mixed correctly and can be easily broken apart with a
screwdriver. The remaining three posts appear to be OK. The posts extend
four feet under ground level and about 2 inches above ground level.
I am attempting to get the original company that drilled and set the posts
to fix the problem, but what they are proposing doesn't sound like a
solution to me. They want to put a layer of hydraulic cement around the tops
of the post to prevent further decay.
I was wondering if anyone had any ideas on what could be done to salvage the
