Concrete Moisture Testing for Hardwood Flooring

Is my concrete slab dry enough for hardwood flooring?

Solid and engineered hardwood are the most moisture-sensitive floors you can put over concrete. Too much moisture in the slab leads to cupping, gaps, buckling, and adhesive failure.

What we do

  • ASTM F2170 RH testing of the slab before installation
  • Comparison to the hardwood and adhesive manufacturer's written limits
  • Moisture mapping to find wet zones under large areas
  • Testing after a leak before re-installing wood

Signs of a moisture problem

Cupping, crowning, gaps, buckling, or boards lifting off the slab.

On-site testing

Los Angeles, Orange, Ventura, Riverside & San Bernardino counties.

Consultation nationwide

Phone or video consultations and report reviews anywhere in the U.S.
