• IMPORTANT!! Forbo strongly recommends that prior to the placement of concrete on site that concrete professionals are consulted regarding the terms for performance of the acoustic underlayment listed below. This will ensure that the necessary and appropriate admix design is specified to eliminate any unnecessary cost or loss once the concrete slab has been poured. If the concrete surface does NOT meet the required level of porosity, failure may occur, and such use voids the warranty of this underlayment.
