New home construction - foundation diagonal crack

Marcel,


We have has a lot of rain lately (remnants of Hurricane Dennis) that very well may have been blown into the basement space thru the window opening in the foundation. The exterior foundation was waterproofed with a black substance (no other info) then a heavy plastic sheeting was tacked over it before being backfilled. I was told by the builder county code requires a gravel type drainage below the foundation floor that wicks to the sump pump well.

I agree, it is somewhat deceiving at first glance. On photos 4 and 5 the strapping may just be compressing the insulation. However in photo 3 I have no doubt that the strap has crushed the slinky wire support inside the ducting. On one of the photos you can see the 7" dia. marking on some of the ducts. The strap in photo 3 look like 7" has now become about 2" resulting in severly reduced airflow to that room ![icon_question.gif](upload://t2zemjDOQRADd4xSC3xOot86t0m.gif)

Once again I appreciate your interest, it is good to have additional opinons, positive or negative.

Thanks

Kevin,


Those flexible ducts restrict some airflow in their natural state let alone when compressed and/or kinked.

I want to mention that you don't need to find out from the builder what the local building inspector does/doesn't allow. You should be able to contact them yourself. Many builders use "that's code" as an answer to anything the buyer brings up. Example: I have friends that have some 3" thick quilted insulation on all the basement walls. When they asked they were told "that's code" yet the builder put the electric panel in the corner (not to code) and to top it off, the insulation has to be compressed to open the panel. It is also interesting that many other new houses in the same developement do not have this insulation.

Having built a house with Ohio's worst builder (not the one referenced above) I will say that I would be very leary of your builder.

icon_smile.gif Hi. Kevin;


Hope you are fine.


Unfortunately, I have exhausted my logical assumptions, which they where, to your problems, and would suggest that you hire a local HI and/or engineer to look at your position first hand. Only so much can be assumed from pictures and the real life observation would tell me the story, but, I am not there to look at it.

One thing for sure that the pictures tell me, is that, the performance standard for the work done is far from meeting the normal performance.
I would personally push this issue if it were my house.

Hope I can assist you more, but more information would be required.

Have a good day.

Marcel
