Masonry cavity wall air space and weeps obstruction prevention system

A method for constructing a masonry cavity wall comprising the steps of:

• constructing a foundation capable of supporting a first wythe and a second wythe separated by an intermediate air space;
• constructing a first wythe;
• affixing holding means to said first wythe for holding excess mortar and other debris which become disposed toward said air space;
• constructing a second wythe having weeps situate therein which communicate between said air space and the outside of said second wythe, and;
• holding with said holding means mortar expressed within said air space during construction of said second wythe.

Apparatus for preventing obstruction of a masonry cavity wall of the type having an inner wythe and an outer wythe separated by an air space comprising:

• a fiberous mesh mat fluid conducting medium having a first side and a second side and a thickness sufficient to substantially fill said air space of said masonry cavity wall,
• means for securing said fluid conducting medium to the cavity side of the inner wythe of a masonry cavity wall;
• a flashing interposed between said fluid conducting medium and said inner wythe, said flashing extending from said inner wythe to the exterior of said outer wythe substantially continuously along said cavity wall;
• weeps communicating through said outer wythe disposed above and proximate to said flashing.

A method for preventing water damage to a masonry cavity wall comprising the steps of:

• constructing a foundation capable of supporting a first wythe and a second wythe separated by an intermediate air space;
• constructing a first wythe;
• affixing holding means to said first wythe for holding excess mortar and other debris which become disposed toward said air space;
• constructing a second wythe having weeps situate therein which communicate between said air space and the exterior of said second wythe;
• and
• holding with said holding means mortar expressed within said air space during construction of said second wythe.

A method for equalization of static pressure within the air space and the exterior of a masonry cavity wall comprising the steps of:

• constructing a foundation capable of supporting a first wythe and a second wythe separated by an intermediate air space;
• constructing a first wythe;
• affixing holding means to said first wythe for holding excess mortar and debris which become disposed toward said air space;
• constructing a second wythe having weeps that communicate between said air space and the exterior of said second wythe, and;
• holding with said holding means mortar expressed within said air space during construction of said second wythe.

A cavity wall comprising:

• a first wythe;
• a second wythe;
• an air space between said first wythe and said second wythe;
• means for removing water from said air space;
• holding means for holding mortar which enters said air space during construction of said second wythe proximate to the masonry joints from which said mortar may be expressed;
• said holding means is comprised of fluid conducting medium through which water and air can flow;
• said holding means substantially fills said air space;
• said holding means is disposed proximate and parallel to said second wythe;
• said fluid conducting medium is comprised of fibrous mesh material affixed to the surface of said first wythe;
• said mesh material has an open area exceeding fifty percent;
• said mesh material resists absorption of water;
• and
• fluid-conducting passages are formed within said air space by said mesh material.
