Wall System

• Weep hole


  A small opening whose purpose is to permit damage of water that accumulates inside a building component or assembly
• Head joint


  Is the vertical joint between two masonry units, perpendicular to the face of a wall
• Cavity


  When talking about cavity walls, it enhances the thermal insulation value of the wall and permit the installation of additional thermal insulation material
• MSNOK


  Types of mortar
• Drywall


  An interior facing panel consisting of a gypsum core sandwiched between paper faces
• Snap tie


  Upon removal of the formwork, these can be snapped off and will snap slightly under the surface of the concrete
• Concrete surface


  Can be sandblasted, ground smooth, and rubbed
• Concrete


  Can be painted or dyed after it has set
• Sheathing lumber


  Produces a board texture
• Concrete color

  Can be controlled with the use of colored cement
• Rowlock


  Is a brick laid horizontally on the longer edge with the shorter end exposed
• Soldier


  Is a brick laid vertically with the longer edge face exposed
• Squared rubble


  Is a masonry wall built of squared stones of varying sizes and coursed at every third or fourth stone
• Wythe


  A vertical layer of masonry that is one masonry unit thick
• Ashlar


  Squared stonework
• Bed joint


  The horizontal layer of mortar beneath a masonry unit
• Form tie hole


  A depression, typically conical in shape, in a cast-in-place concrete wall that remains after the protruding portions of a form tie are removed
• Common bond


  Laid with five courses of stretchers followed by one course of headers
• Form tie


  It is a steel or plastic rod with fasteners on either end, used to hold together the two surfaces of formwork for a concrete wall
• Cavity wall


  Are constructed of a facing and a backing wythe of either solid or hollow masonry units, completely separated by a continuous air space and bonded with metal wall ties or horizontal joint reinforcement
• Mortar


  It is a plastic mixture of cement or lime, or a combination of both, with sand and water, used as a bonding agent in masonry construction
• Collar joint


  Is the vertical joint between two wythes of masonry
• Tilt-up construction


  A method of constructing concrete walls in which panels are cast and cured flat on a floor slab, then tilted up into their final positions
• Snap tie and she bolt


  Two basic types of form ties
• Shear wall


  A stiff wall that imparts lateral force resistance to a building frame
• Rubble


  Unsquared stones
• Bush hammered finish


  Are coarse-textured finishes obtained by fracturing concrete or stone surface with a power-driven hammer having a rectangular head with a corrugated, serrated, or toothed face
• Natural stone


  Is durable, weather-resistant construction material that may be laid in mortar much like clay and concrete masonry units to make both bearing and nonbearing walls
• Wall


  Are the vertical constructions of a building that enclose, separate, and protect its interior spaces
• Exposed aggregate finish


  A concrete surface in which the coarse aggregate is revealed
