As concrete dries, moisture migrates from the bottom of the slab to the surface where it can evaporate away.

F requires three test holes for the first ft 2 and, at least, one additional hole for each additional ft 2. Click here for a moisture meter. October 27, at In-situ probe concrete testing: Thanks for the reply, Patrick. Logically then, moisture levels at the bottom of a slab will read higher from those at the surface. If i have an area of approx sq ft and have done the required testing for the area, and 5 fail and 3 pass does the whole area f2170-11

10 Guidelines for ASTM F2170 Preparation and Testing

The instruments have proven to perform well in rough mill environments with day-to-day usage. Without studying pages and pages of operation manuals: Does the finish roof product have specifications for testing the concrete deck? Many contractors use vapor barriers directly under the slab to slow moisture permeation. As any professional knows, ASTM standards are established to help guide industry testing and also to help ensure standardized best practices to protect both the installer and the consumer.


The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Without it, even a well-dried and functioning foundation can end up with concrete slab moisture problems. Contact My Account 0 items April 3, at How do you handle this problem? This process requires time and quantifiable concrete moisture measurements to verify. At this point, if one test fails, they all fail.

Jason, I appreciate this means to contact you. September 6, at April 7, at 3: First, I have to state that F is specified for interior applications that are under consistent ambient air controls. Section 9 of the standard requires that both the slab and the ambient air above it must be at service conditions for a minimum of 48 hours before testing. The depth is calculated to the bottom of the test hole the location of astmm installed Qstm sensor or probe.
