SINGLE LAYER SCREEDS

The auto-levelling single layer screed is made with cellular concrete of medium density (with sand) over which the pavement may be bonded directly. The cellular sub-stratum can have a density of between 1000 and 1300 kg/m3. It units properties of lightness of the specific weight, thermal and acoustic insulation and significant productivity thanks to its being laid in a fluid state.
