• wear

  the removal of material or impairment of surface finishing through friction or impact use.
  
  

• weathering

  natural alteration by either chemical or mechanical processes due to the action of constituents of the atmosphere, surface waters, soil and other ground waters, or to temperature changes; the inclined top surface of a stone such as a coping, cornice, or window sill.
  
  

• wedging

  splitting of stone by driving wedges into planes of weakness.
  
  

• weep holes

  openings placed in mortar joints of facing material at the level of flashing to permit the escape of moisture.
  
  

• wind

  (wined) - a twisting warp from cutting slabs in the gang saws.
  
  

• wire saw

  method of cutting stone by passing a twisted, multistrand wire over the stone and immersing the wire in a slurry of abrasive material.
  
  

• wythe

  the inner or outer part of a cavity wall.
