- Weep
A weep or a weep-brick is a small opening that allows water to drain from within an assembly. Weeps are located at the bottom of the object to allow for drainage; the weep hole must be sized adequately to overcome
surface tension .In building construction, weeps are typically found in a masonry cavity wall, just above the flashing. Weeps may take several forms, including:
*Open head joints (the vertical joints between
brick s)
*Cotton rope wicking
*Formed plastic or metal tubes, which may include insect screening.Weeps may also be necessary in a
retaining wall , so water can escape from the retained earth, thus lessening thehydrostatic load on the wall and preventing moisture damage from freeze/thaw cycles. In such cases the weeps consist of small-diameter plastic, clay or metal pipes extending through the wall to a layer of porousbackfill .Typically, weeps are arranged to direct water which may have entered an assembly from outside back to the outside. Weeps may also be found in metal
window s and glazedcurtain wall s to permit internalcondensation to escape.References
