CONCRETE MOISTURE TEST SERVICES

Concrete is permeable, & ground moisture can slowly seep upward in the form of vapor and adversely affect anything that rests on it.

What Is ICRI-Certified Concrete Substrate Moisture Testing?

All floor covering and applied coating manufacturers specify that concrete substrates, regardless of age must be tested for moisture & alkalinity before being installed. In every situation, when we have inspected flooring failures, it was found the tests were not done to ASTM International Standards & the results were invalid. Floor covering & applied coating manufacturers will not warranty their products if they are improperly installed.

ASTM TEST METHODS

Whittco Hawaii utilizes the current revised standards and testing tools for independent 3rd-party testing of your concrete flooring substrates and walls. Our accurate testing model is free from any and all financial influences which might sway the results in one way or another. With Whittco Hawaii, you get the truth, and nothing but the truth!

AVOID COSTLY FLOORING FAILURES

An independent, third party performing & certifying the test results is the best way to guarantee the accuracy and acceptability of the results. Certified testing is a fraction of the cost of replacing a failed floor. We are an independent, third party certified for doing the above ASTM International Test Methods.  Core drilling and independent lab testing services are available for analysis of problem slabs.  We also test gypsum underlayments, lightweight (gypcrete) concrete substrates too!
