|In response to Re: Under slab leak - What now??|
: Hi Mitch,
: : We had an intermittent leak which was originally diagnosed as a pinhole leak which was sometimes plugged by debris. It turned out to be a leak in a pipe under our concrete slab.
: I'm a big fan of running under-slab plumbing in chases...
: : It was probably leaking for months. After location by a detection service it was repaired by re-routing through the attic. The carpeting in several rooms and hallways smelled musty and were removed by the remedidation service recommended by the insurance company. After 3 weeks of dehumidifers and fans, a calcium chloride test shows higher levels than recommended for carpeting (5 gal/day/1000 sq ft). What do we do now.
: I would want to know if the soil under the slab is moist because of the leak, or has it always been wet?
: Does the rest of your property have high soil moisture levels?
: If the moisture is just from the leak, you likely need more time with the dehumidifiers and fans.
: Good health, Weogo
Thanks for your response. Since we have never had any dampness or problems of this sort until the leak, I assume that it is the source of the problem. I don't know how the slab foundation was prepared - that is if there is a layer of sand over a vapor barrier or something else. If the former, it could be preventing disapation of the water.
