Long live the beauty of block!
Long live the beauty of block!-with Dur-o-wal to make it more than twice as strong!
When reinforced every second course with Standard Dur-o-wal, the flexural strength of a masonry wall increases 71 per cent-comparable to other types of reinforcement used every course. But Dur-o-wal can do even better. When Extra Heavy Dur-o-wal is used every course with Class A mortar, flexural strength increases a mighty 261 per cent! Those are solid facts, established by independent engineering tests and research.
Builders everywhere are relying on Dur-o-wal's trussed design, butt-welded construction, scientifically deformed rods, to give good-looking modern masonry extra years of life. Nationally wanted, Dur-o-wal is nationally distributed. Wherever you build a masonry wall, you can get Dur-o-wal. See us in Sweet's.
