EBSARY FLOORFILLER BLOCKS are used in rein-forced concrete floors a- a tiller between concrete beams. The advantages olthis type of Hoor construction are thai it is light in weight,—thus saving in steel; on-lj <i minimumamount of form- an- required; it givesa flat ceiling, and only two coats ofplanter are required^ In freezingweather the block helps largely to pro-tect the concrete from freezing wlun being placed. This type of Hoor ismore sound proof than any floor nowon the market. Full information and estimates will gladly be given to Architect-, Engineersand Contractors. MADE IN CANADA.
