with Dur-o-wal
Tests prove this easier way to tie composite walls
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.
