The floor contractor installing a floor not only has to deal with the floor planks themselves, but also with all other materials in contact with or surrounding the floor he is about to install. The first consideration is the moisture content of the floor planks as delivered by the floor manufacturer to the site. A […]

When a concrete slab has not completely dried out and an LVT floor is installed, no more moisture can evaporate through the surface. However, over time the dryer top portion of the concrete will pull up the excess moisture from the bottom until the moisture is equally distributed between top and bottom portions of the […]

The Ligno-DuoTec BW is a dual-depth pinless meter for wood floors, bamboo, and gypsum. The meter in pinless mode also gives comparative readings of concrete and other materials (Photo 2). The Ligno-DuoTec BW meter can be used with the RH BluePeg Probes to measure ambient conditions of air and in-situ RH probes in concrete. Taking […]

The RH BluePeg uses a single microchip, factory calibrated to NIST Standards. Each BluePeg comes with a NIST traceable certificate. The RH BluePeg probes comply with the latest ASTM F2170. For the first year, Lignomat offers to check the probe calibration at no charge. For sensitive tests, the calibration of the removable probes could be […]

When placing a floor covering over concrete slabs, a contractor must first evaluate the concrete to ensure proper acclimation has been met. We often use two different methods for evaluating moisture in materials: a qualitative analysis and a quantitative analysis. Qualitative vs Quantitative Analysis Often times with a moisture meter we describe the scale as […]

Water in concrete is presented in three stages: as free water held by capillarity, as absorbed water held by surface forces and as bound water held chemically. The ideal method of moisture measurement should quantify amounts of these three states, but this is a difficult task because moisture in concrete is not uniformly distributed, and […]

Why the In-situ Probe Test is important Concrete slabs are an integral part of a building. Excess moisture in a slab will over time be released and can affect the entire building including in particular floor coverings. The ASTM F2170 in-situ probe test was created to accurately measure the moisture that would be released once […]
