About EYLARK

An independent field-testing and diagnostic service.

EYLARK helps customers understand concrete moisture conditions before installation, investigate moisture-related flooring concerns, document water-damage conditions, and obtain technical support for disputes — with clear, documented, method-led reporting.

Method over meter

Testing follows published ASTM procedures, with locations and conditions documented for each project.

Independently owned

EYLARK sells no flooring, adhesives, or mitigation products. The only product is a defensible reading of the slab.

Honest reporting

We distinguish observed conditions, measurements, interpretation, and limitations — and don't turn incomplete evidence into certainty.
