The TRAMEX DL-RHTX Feedback DataLogger and App collect up to 100,000 data point entries for relative humidity, temperature, dew point, and grains per pound. The information is transmitted wirelessly to your mobile device via Bluetooth technology.
Even if a concrete slab has cured, it is never completely free of moisture. The porous nature of concrete allows moisture below the concrete and within it to migrate up through the concrete capillaries and escape through the path of least resistance, a process known as moisture vapor transmission (MVT). Excessive MVT can cause bonding failures or flooring to delaminate.
For concrete and cementitious screeds to receive a floorcovering we know that the base must be suitably “dry enough”. This is to prevent damage to the flooring material and to ensure a proper bond with adhesives.
