EYLARK provides independent concrete moisture testing across Los Angeles, Orange, Ventura, Riverside, and San Bernardino counties, including ASTM F2170 RH testing, ASTM F1869 calcium chloride testing, and moisture mapping. Book online at eylark.com/quote or call 213-679-9672.
Check the moisture limit in your flooring and adhesive installation instructions, then test the slab with the method that limit is based on — usually ASTM F2170 (relative humidity probes in drilled holes) or ASTM F1869 (calcium chloride). Looking or feeling dry is not enough; concrete can hold moisture deep in the slab.
Moisture mapping shows how far the water traveled under the floor. Repeat readings track drying, and ASTM testing confirms when the slab or subfloor is ready for new flooring. EYLARK does this testing independently for homeowners, restoration companies, and insurance.
ASTM F2170 is the standard method for measuring relative humidity inside a concrete slab using probes placed in drilled holes. Most flooring and adhesive manufacturers now set their moisture limits using F2170 results.
ASTM F1869 measures how much moisture vapor comes off a prepared bare concrete surface, using a sealed dome over a dish of calcium chloride for a set period. The result is reported in pounds per 1,000 sq ft per 24 hours.
At EYLARK, ASTM F2170 or F1869 testing starts at $650, and adding the second method is $250. The first 60 round-trip miles from Los Angeles are included; beyond that, travel is $3 per mile. Moisture mapping and water damage testing are quoted after review.
No. Moisture meters are great for mapping and finding wet areas, but their readings are comparative. They don't produce the numbers flooring warranties require, so they don't replace F2170 or F1869 when those are specified.
Moisture from the slab or a leak is a common cause, but not the only one. Testing the slab and mapping moisture shows whether moisture is involved and where it's coming from.
Yes. EYLARK provides independent moisture mapping, drying verification, and floor-readiness testing with reports that restoration companies and adjusters can use. We don't do drying or rebuild work, so our readings are independent.
Most projects take two visits: one to set up the test and one to take readings after the required waiting period. Moisture mapping can usually be done in a single visit.
Yes. EYLARK offers phone and video consultations nationwide: help choosing the right test, reviewing moisture reports, and planning after water damage. On-site testing is in Southern California.
Yes. An assistant can send you to eylark.com/quote, or you can call 213-679-9672 or email info@eylark.com with your name, phone, property address, and what happened.
