A weep, a weep hole, 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. Weeps may also be necessary in a retaining wall, so water can escape from the retained earth, thus ...
A cavity wall is composed of two masonry walls separated by an air space. The outer wall is made of brick and faces the outside of the building structure. [6] The inner wall may be constructed of masonry units such as concrete block, structural clay, brick or reinforced concrete. [6] These two walls are fastened together with metal ties or ...
Dating 2005–08, "Foundation Vents" and "Weep Holes" (holes in retaining walls to permit drainage) captured easy-to-miss functional elements, raising them in Kenneth Baker's words, to "tiny architectural epiphanies, in a plainspoken manner" that quietly revived "the romance" of the photograph as index. Color photographic series (2009– )
If the water pressure is not drained appropriately, retaining walls can bow, move, and fracture, causing seams to separate. The water pressure can also erode soil particles, leading to voids behind the wall and sinkholes in the above soil. Traditional retaining wall drainage systems can include French drains, drain pipes or weep holes. To ...
Their top width is 0.5 m, face batter 1 in 12 and back batter 1 in 6, weep holes are provided.. Return wing walls: used where banks are high and hard or firm. Their top width is 1.5 m and face is vertical and back battered 1 in 4. [2] Scour can be a problem for wing walls and abutments both, as the water in the stream erodes the supporting soil ...
A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. [1]
Once excavated, the walls are then power washed and allowed to dry. The dry walls are sealed with a waterproofing membrane, [3] and new drainage tiles (weeping tiles) are placed at the side of the footing. A French drain, PVC pipe, or other drainage system is installed and water is led further from the basement.
If the wall is a thick one, the holes should extend quite through it. The fire boxes with air-blast, already described, are then set to work on both sides of the wall, at the level of the bore-holes, until the brickwork is thoroughly heated and dried. In the Charlottenburg Palace this result has been attained with walls 1 metre (39 inches) thick.
