A window well with a window well cover made from polycarbonate. A window well is a recess in the ground around a building to allow for installment of bigger windows in a basement either below ground or partially below ground. By making it possible to put in a larger window, the window can act as a safer emergency exit in case of fire as well as ...
A drain-waste-vent system (or DWV) is the combination of pipes and plumbing fittings that captures sewage and greywater within a structure and routes it toward a water treatment system. It includes venting to the exterior environment to prevent a vacuum from forming and impeding fixtures such as sinks, showers, and toilets from draining freely ...
French drain. A French drain[1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain[1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area. The perforated pipe is called a weeping tile (also called a ...
Geometry of a fully penetrating well drainage system in a uniform, isotropic aquifer Geometry of a partially penetrating well drainage system in an anisotropic layered aquifer The basic, steady state , equation for flow to fully penetrating wells (i.e. wells reaching the impermeable base) in a regularly spaced well field in a uniform unconfined ...
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 ...
Rainscreen. A rainscreen is an exterior wall detail where the siding (wall cladding) stands off from the moisture - resistant surface of an air/water barrier applied to the sheathing to create a capillary break and to allow drainage and evaporation. The rainscreen is the cladding or siding itself [1] but the term rainscreen implies a system of ...
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 ...
Water build up inside window wells, after heavy rain or snow, can lead to leaks through basement window seams. Window well covers can be used to prevent water from accumulating in the window well. Ground saturation is another common form of basement leaks. When the footing drain fails the ground around the basement can contain too much water ...
