The strength of a masonry wall is not entirely dependent on the bond between the building material and the mortar; the [[friction]] between the interlocking blocks of masonry is often strong enough to provide a great deal of strength on its own. The blocks sometimes have grooves or other surface features added to enhance this interlocking, and some ''dry set'' masonry structures forgo mortar altogether.
