The moisture is already in the slab.

Every slab holds water, from the mix, the ground, the site, and flooring seals it in. We read the moisture inside the slab, to your manufacturer’s warranty standard, before the floor traps it. North America’s leading independent moisture testing company for two decades.

Why it matters

Seal a wet slab, and the floor fails from underneath.

Trapped moisture attacks adhesive, blisters resilient flooring, cups wood, and feeds mold, months after everyone left the site. A surface guess won’t catch it. You have to read inside the slab.

01

ASTM F2170, in-situ RH

Probes read relative humidity at depth inside the slab, the moisture your floor will actually live with.

02

ASTM F1869 & F710

Calcium chloride MVER and the standard practice for preparing concrete to receive resilient flooring.

03

Vapor retarder borescope

An add-on that answers the question a moisture number can’t: is a retarder even down there, and is it intact?

How it works

Warranty-grade results, on your schedule.

01
STEP 01

Send the spec

Tell us the flooring system and its manufacturer. The warranty defines the standard we test to.

02
STEP 02

We place the probes

Certified technicians install F2170 probes and run F1869 or F710 as required, working around the other trades.

03
STEP 03

You get the documentation

Results tied to the warranty requirement, in a format that satisfies the manufacturer and holds up in a dispute.

Common questions

Concrete moisture, answered.

Surface readings miss the moisture held deep in the slab, exactly the moisture that gets trapped and drives failures once flooring seals the top. ASTM F2170 reads relative humidity at depth, which is why manufacturers write their warranties around it.

It depends on the manufacturer and system. F2170 (in-situ RH) is the most widely required; F1869 (calcium chloride MVER) and F710 (standard practice) apply in specific cases. Send us the system and we’ll test to the exact standard the warranty names.

A moisture number tells you the slab is wet; it can’t tell you why. The borescope inspection confirms whether a vapor retarder is present beneath the slab and whether it’s intact, the root-cause context that changes the remediation decision.

Yes, all 50 states including Hawaii and Alaska, plus Canada and Puerto Rico, with certified technicians and consistent reporting on every project.

Yes, and it should. Flatness, subfloor analysis, photo survey, and 3D scanning can all be captured in the same mobilization, so you get a full condition record without paying for four separate visits.
