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 tie not only makes for easier construction and lower cost-but also provides increased compressive strength, marked improvement in resistance to moisture penetration, comparable transverse strength, comparable mortar bond.
