TOGETHER FOR KEEPS
-with Dur-o-wal
Tests prove this easier way to tie composite wall
IS BETTER TOO MUCH BETTER!
Impartial tests, we mean, conducted at a university-affiliated research laboratory. Test techniques were adaptions of standard masonry construction. Conclusions: In comparison with header-tied walls, the Dur-o-wal brand tie not only makes for easier construction and lower cost-but also means better walls with increased compressive strength, marked improvement in resistance to moisture penetration, comparable transverse strength, comparable mortar bond.

Strength with flexibility-the basic factors for repair-free composite wall are assured by Dur-o-wal. Around corners, that is, as well as straight stretches. Positive, continuous reinforcement at corners is easily formed on the job-even easier than with prefabricated Dur-o-wal corner units, such as shown in this picture.
