A crying , a weep hole , or weep-brick is a small opening that allows water to flow from inside the assembly. Weeps are located at the bottom of the object to allow drainage; weep holes should be of sufficient size to overcome surface tension.
Weep may also be needed on the retaining wall, so water can come out of retained soil, thus reducing hydrostatic load on the walls and preventing moisture damage from freezing/liquefaction cycles. In such cases, weep consists of small diameter plastic pipe, clay or metal that extends through the wall into a porous porous layer.
Typically, weeps are set to direct water that may have entered the assembly from the outside back to the outside. Weeps can also be found in metal shutters and shiny curtain walls to allow condensation of interstitial escape. The automotive water pump has a hole to protect the pads by leaking water leaking past the seal.

Masonry
In building construction, weeps are usually found in brick walls or stone cavity walls, just above the flash. The cavity serves as a way to drain this water out through the clanging holes. The crying holes allow the wind to create airflow through the cavity. The flow removes the water that evaporates from the outer cavity. The crying holes are also placed above the window to prevent dry clots from the wooden window frames.
Open the head joint
The process of open head joint is done by removing mortar from the joint. This creates an open hole of the same size from a typical joint distance. This is the most common and most effective method to evaporate water from the cavities. The distance between the open head joints can be done every 24 inches (61 cm). One of the problems with this method is that the open head joint makes a large hole that may be unattractive. Some maintenance workers may also accidentally patch up the holes without realizing that they are crying holes. There are some products such as aluminum vents and plastic boxes that can be inserted into small holes to make them less conspicuous.
Wrinkle of cotton rope
The cotton axis can be used to form weeps. Ropes of up to 12 inches (30 cm) are placed in joints. The other end of the rope is extended to the cavity wall. Cotton can absorb moisture inside the wall and dry it out, but it is also true - it is possible for a cotton rope to spray a little moisture from the outside into the wall. The evaporation process is slower than with small holes. Also, cotton can burn.
Tubes
Another type of weeps is a tube that can be made formed by using plastic or hollow metal. The distance between the tubes is about 16 inches (41 cm) apart. Installation of the tube is done at an angle to allow water to drip out. If the angle is too steep, the opening hole inside the wall cavity will be too high to remove water. If the angle is too flat, the mortar used to lay the bricks can fall into the cavity and block the tube. Sometimes a shallow pebble layer is laid to prevent mortar falling from the tube. The thickness of the plastic tube, however small, will create a small dam that allows water to flow inside the wall cavity.
Another technique for forming a tube rather than using a permanent tubing material is by using an oiled rod or rope. The oiled rod or rope will be placed and crushed into the joint. Oil prevents mortar and rod or rope bonds can be removed after mortar is set, creating a hole similar to the use of a tube.
The advantages of this type of tube are not too flashy. However, these small holes do not allow air to circulate and excrete water vapor very well.
Corrugated channel
Newer woven technology uses corrugated plastics to create a channel/tunnel that forms the underside of the mortar bed joint. The tunnel quickly drains water out of the wall through the weep hole holes and ensures that water can come out at the lowest point on the wall. The corrugated plastic ointment generally mixes with the mortar and is less conspicuous than the weeping rope.
