Hi guys, this is my first post to this forum. I found this forum while searching info for an inspection. I'm a Building Inspector that does a lot of 'adverse conditions' inspections. This one is a bit out of my normal routine.
Currently I'm trying to assist a client with a problem as follows ...
New construction concrete mid-rise, occupancy started spring of this year. Client has been living in a 2 bed Condo for about 6 months and feels the place is making them sick. Unit has about 1300+ sqft. of exposed concrete on the walls and ceilings.
I took various moisture/RH readings.
Concrete surface 30-45%
1/8"-1/4" subsurface 50-75%
1" subsurface 80-99.9%
ambient RH 17-22%
At first I thought this might be an issue of emissions but based on the low ambient RH, I'm wondering if all the concrete isn't sucking the place dry.
Client states walls darken when it rains outside and portions of the floor blister up. Wood laminate floor over vapor barrier.
I've done other inspection work for this client and have made it clear that this isn't my field of expertise. I'm looking for information and ideas on what could be going on here so that I can point the client in the right direction.
I grew up in the trades on jobsites, so I'm pretty hearty and not the sensitive type. I started getting congested after an hour in the place.
Any thoughts or references for things to read are greatly appreciated.
Thanks Markus
