I considered the unreliability of the surveymaster. That may be the case yet I dont think so. I tested on the tile as well as pulled corners of carpet to test on slab with similar findings. Tried it inside and out (outside had much lower readings) the home is vacant so it probably is not aired out allowing the moisture level to build up.

No irrigation. 3 Year old tract with PEX through the ceiling. No indication of leak at supply to main. Yes expansive soils are an issue. Any thoughts on type of specialist to refer them to??

Thanks for the reply- Out here in the desert, they do not use a vapor barrier below the slab. Any thoughts on issues?

Hello All- Hoping you can help Just inspected a 3 yr old home in the phoenix area. The home is slab on grade. The seller disclosed previous issue with excessive moisture build up b/w carpetpad and foundation. Builder documented (at 1.5 yrs old) the issue as ordinary residual moisture from the concrete that collected beneath one of those plastic office chair mats. I tested multiple areas throughout the home (primarily tiled areas) with GE Protimeter Surveymaster) The reading was off the chart (in the 700's range in relative moisture) in 8 of 10 locations. I tested beneath carpet and had same experience. Checked for slab leak - none. Decent drainage with little recent rain. What do you think would be the cause? What are potential issues? Would carrying on with decent ventilation within the home be sufficient? The buyer asked about putting in Pergo - I said not a good idea as it would trap the moisture. Please share your thoughts.

Have you seen this before? Home is about 2 yrs old. Where the concrete tile meets the rolled roofing material at the flat patio roof, the membrane is exposed. The grey areas in the photo are the fasteners. What is your take on this? The rolled roofing material does extend beneath the paper but the paper is subject to the deteriorating effects of the desert sun. Download Attachment: P1010014.JPG 157.86 KB

On a new construction final walkthru inspection, I called out the lack of airgap/highloop (AG/HL) at the dishwasher. The superintendent gave me a line that it is "code" for dishwashers to have them installed internally when manufactured. After a little debate, returned home to do research and get my facts straight. I found specific citing of necessity of AG/HL in code and also pulled the manufact install instructions and found their "recommendation" for a AG/HL. It's obvious that I have the docs for the repair to be made, but have read conflicting info on other sites about the necessity of an AG/HL. What have you guys experienced with this? What is your stance?
