BUILD WITH BLOCK
and build for keeps-with Dur-o-wal
Not how cheap, but how long until the wall needs costly repairs? That's the question if you really want to get the most for your building dollar. It's the reason why Dur-o-wal masonry wall reinforcement is specified throughout the continent. Dur-o-wal can more than double flexural wall strength and, when used in lieu of brick headers for composite masonry walls, increases ultimate compressive strength. Years which more than make up for the initial cost of Dur-o-wal-are added to masonry wall life. Please pass the evidence? Write to nearest address below for new comprehensive Dur-o-wal data file.
