<p>The method is for laying floors of compressed saw dust plates (4), cellular plastics and a plastics damp-proofing foil (3) on a concrete base (1). Rigid spars (5) are positioned at right-angles to the plate longitudinal direction with a centre-to-centre distance of a max. of 60 cms., the joint between adjoining plates being directly over the spars. The foil (3) is placed on top of the cellular plastics (2) and the spars are positioned between the foil and the plates, or between the concrete base (1) and the plastics.</p> |
