A basement or cellar is one or more floors of a building that are completely or partly below the ground floor . Especially in residential buildings, it often is used as a utility space for a building, where such items as the furnace , water heater , breaker panel or fuse box , car park , and air-conditioning system are located; so also are amenities such as the electrical system and cable television distribution point. In cities with high property prices, such as London , basements are often fitted out to a high standard and used as living space.

Spades are made in many shapes and sizes, for a variety of different functions and jobs, and there are many different designs used in spade manufacturing. People often mistakenly use the word shovel interchangeably with spade but shovel is a generic term for a variety of tools that include numerous broad-bottomed versions for moving loose materials, such as
201-424: A concrete pump , or they will use concrete masonry units (block walls). Rock may also be used, but is less common. In monolithic architecture , large parts of the building are made of concrete; in insulating concrete form construction, the concrete walls may be hidden with an exterior finish or siding . Inside the structure, a single Lally column , steel basement jack, wooden column or support post may hold up
268-495: A french drain may need to be used to prevent water from entering the basement at the bottom of the wall. Walls below grade may need to be sealed with an impervious coating (such as tar ) to prevent water seepage. A polyethylene of about 6 mil ( visqueen ) serves as a water barrier underneath the basement. Some designs elect to simply leave a crawl space under the house, rather than a full basement due to structural challenges. Most other designs justify further excavations to create
335-403: A "coal shovel", "snow shovel", "grain shovel", etc., whereas spades tend to have a sharpened edge, curved profile, and pointed end better designed for digging. Noting that the term "garden spade" is attached to certain sharp-edged but square ended tools suited to cutting through sod. The most common garden spade typically has a long handle, is wide, and is treaded (has rests for the feet to drive
402-766: A "roundpoint" shovel, which has a wider body and tapered tip. English spade is from Old English spadu, spædu (f.) or spada (m.). The same word is found in Old Frisian spade and Old Saxon spado . High German spaten only appears in Early Modern German , probably loaned from Low German . In the Netherlands, Denmark, Sweden and Norway the word is spade as well. Other Scandinavian forms are in turn loaned from German . The term may thus not originate in Common Germanic and appears to be

A digging fork , or grape, not referred to as a spade, is forked much like a pitchfork, and is useful for loosening ground and gardening. The fishtail spade has a flared triangular blade combining the versatility of the dutch hoe and power of
536-443: A closet. The main point of distinction between this type of basement and the two others lies in its being either entirely unmodified (unlike the finished basement) beyond the addition of furniture, recreational objects and appliances, and/or exercise equipment on the bare floor, or slightly modified through the installation (besides any or all of the aforementioned items) of loose carpet and perhaps simple light fixtures. In both cases,
603-525: A full-height basement, sufficient for another level of living space. Even so, basements in Canada and the northern United States were typically only 7 feet 10 inches (2.39 m) in height, rather than the standard full 8 feet (2.44 m) of the main floors. Older homes may have even lower basement heights as the basement walls were concrete block and thus, could be customized to any height. Modern builders offer higher basements as an option. The cost of

Usually a part of the basement is unfurnished and is used for storage, a workshop, and/or a laundry room; when this is the case the water heater and furnace will also often be located there, although in some cases the entire basement is finished, and the water heater and furnace are boxed off into
737-433: A large number of projects in the 100–200 square meter bracket. There are a smaller number of projects in the 200–500 square meter bracket under construction. It is also not unusual to see multi-level retrofit basements. These are considerable works of civil engineering and require some skill and intuitive understanding as well as good engineering. Some of the more grandiose of these basement projects have been widely reported in

The only exceptions are when the entire basement is nearly entirely underground, and a stairwell leads up nearly a floor's worth of vertical height to lead to the outdoors. Generally, basements with only an emergency exit well do not count as walk-out. Walk-out basements with at-grade doors on one side typically are more costly to construct since
871-516: A subbasement is more difficult, costly, and time-consuming than building a basement as the lowest floor. Subbasements are even more susceptible to flooding and water damage than basements and are therefore rare, except in dry climates and at higher elevations. Some famous landmarks contain subbasements. The subbasement of the US Capitol Building is used as storage and that in the White House
938-404: A work-out area. It is also common to have a secondary (or primary) home office in a partially finished basement, as well as a workbench and/or a space for laundry appliances. Toilets and showers sometimes exist in this variety of basement, as many North American basements are designed to allow for their installation. In London the construction of finished retrofit basements is big business with
1005-448: Is considered necessary. Historically, basements have become much easier to build (in developed countries) since the industrialization of home building. Large powered excavation machines such as backhoes and front-end loaders have dramatically reduced the time and manpower needed to dig a basement as compared to digging by hand with a spade , although this method may still be used in the developing world. For most of its early history,
1072-399: Is typically gravel or crushed stone to facilitate draining. The floor is typically four inches (100 mm) thick and it rests on top of the foundation footings. The floor is typically sloped towards a drain point, in case of leaks . Modern construction for basement walls typically falls into one of two categories: they will be made of poured-in-place concrete using concrete forms with
1139-421: Is typically separated from the concrete by only a thin foam underlay. Radiant heating systems may be embedded within the concrete floor. Even if unfinished and unoccupied, basements are heated in order to ensure relative warmth of the floor above, and to prevent water supply pipes, drains, etc. from freezing and bursting in winter. It is recommended that the basement walls be insulated to the frost line. In Canada,
1206-546: Is used to store guest items. According to the international Oxford Dictionary of English , a finished fully underground cellar is a room below ground level in a house that is often used for the storage of wine or coal ; it may also refer to the stock of wine itself. A cellar is intended to remain at a constant cool (not freezing) temperature all year round and usually has either a small window/opening or some form of air ventilation (air/draught bricks, etc.) in order to help eliminate damp or stale air. Cellars are more common in
1273-428: Is usually desirable to finish a crawl space with a plastic vapour barrier that will not support mold growth or allow humidity from the earth into the crawl space. This helps insulate the crawl space and discourages the habitation of insects and vermin by breaking the ecological chain in which insects feed off the mould and vermin feed on the insects, as well as creating a physical inorganic barrier that deters entrance into
1340-424: Is usually used with buildings when the space below the ground floor is habitable and with (usually) its own access. The word cellar applies to the whole underground level or to any large underground room. A subcellar or subbasement is a level that lies below the basement or cellar. A basement can be used in almost exactly the same manner as an additional above-ground floor of a house or other building. However,
1407-482: The Gulf of Mexico , basements are usually not financially feasible unless the building is a large apartment or commercial structure. Excavation using a backhoe or excavator is commonly used to dig a basement. If shelf rock is discovered, the need for blasting may be cost prohibitive. Basement walls may need to have the surrounding earth backfilled around them to return the soil to grade. A water stop, some gravel and

One usually finds within it a water heater, various pipes running along the ceiling and downwards to the floor, and sometimes a workbench, a freezer or refrigerator, or a laundry set (usually found in older homes). Boxes of various materials, and objects unneeded in the rest of the house, are also often stored there; in this regard, the unfinished basement takes the place both of

Garages on both levels are sometimes possible. As with any multilevel home, there are savings on roofing and foundations. A walk-out basement is any basement that is partially underground but nonetheless allows egress directly outdoors and has floating walls. This can either be through
1608-566: The United Kingdom in older houses, with most terraced housing built during late 19th and early 20th centuries having cellars. These were important shelters from air raids during World War II . In parts of North America that are prone to tornadoes (e.g. Tornado Alley ), cellars still serve as shelter in the event of a direct hit on the house from a tornado or other storm damage caused by strong winds. Except for Britain, Australia and New Zealand, cellars are popular in most western countries. In
1675-553: The United Kingdom, almost all new homes built since the 1960s have no cellar or basement due to the extra cost of digging down further into the sub-soil and a requirement for much deeper foundations and waterproof tanking. The reverse has recently become common, where the impact of smaller home-footprints has led to roof-space being utilised for further living space and now many new homes are built with third-floor living accommodation. For this reason, especially where lofts have been converted into living space, people tend to use garages for
1742-540: The actual floor remaining below grade. In most parts of North America, it is legal to set up apartments and bedrooms in daylight basements, whether or not the entire basement is above grade. Daylight basements can be used for several purposes—as a garage , as maintenance rooms, or as living space. The buried portion is often used for storage, laundry room , hot water tanks, and HVAC . Daylight basement homes typically appraise higher than standard-basement homes, since they include more viable living spaces. In some parts of
1809-412: The additional depth of excavation is usually quite expensive. Thus, houses almost certainly never have multi-storey basements though 9 feet (2.74 m) basements heights are a frequent choice among new home buyers. For large office or apartment buildings in prime locations, the cost of land may justify multi-storey basement parking garages. The concrete floor in most basements is structurally not part of
1876-415: The area. Basement floor drains that connect to sanitary sewers need to be filled regularly to prevent the trap from drying out and sewer gas from escaping into the basement. The drain trap can be topped up automatically by the condensation from air conditioners or high-efficiency furnaces . A small tube from another downpipe is sometimes used to keep the trap from drying out. Health Canada advocates
1943-475: The basement must be graded such that water flows away from the basement wall. Downspouts from roof gutters should drain freely into the storm sewer or directed away from the house. Downspouts should not be connected to the foundation draintiles. If the draintiles become clogged by leaves or debris from the rain gutters, the roof water would cause basement flooding through the draintile. Damp-proofing or waterproofing materials are typically applied to outside of
2010-413: The basement took one of two forms. It could be little more than a cellar, or it could be a section of a building containing rooms and spaces similar to those of the rest of the structure, as in the case of basement flats and basement offices. However, beginning with the development of large, mid-priced suburban homes in the 1950s, the basement, as a space in its own right, gradually took hold. Initially, it
2077-504: The basement wall. It is virtually impossible to make a concrete wall waterproof, over the long run, so drainage is the key. There are draining membranes that can be applied to the outside of the basement that create channels for water against the basement wall to flow to the foundation drains. Where drainage is inadequate, waterproofing may be needed. There are numerous ways to waterproof a basement, but most systems fall into one of three categories: The waterproofing system can be applied to

2144-455: The case of a walk-out basement, a door) to include the basement square footage as living space. Spade A spade is a tool primarily for digging consisting of a long handle and blade, typically with the blade narrower and flatter than the common shovel . Early spades were made of riven wood or of animal bones (often shoulder blades ). After the art of metalworking was developed, spades were made with sharper tips of metal. Before
2211-412: The ceiling of the basement (since there is not an empty floor below to run the ducts). Ducts extending from the ceiling down to the floor help heat the cold floors of the basement. Older or cheaper systems may simply have the heating vent in the ceiling of the basement. The finished floor is typically raised off the concrete basement floor. In countries such as Canada, laminate flooring is an exception: It
2278-457: The cellar and of the attic . Home workshops are often located in the basement, since sawdust, metal chips, and other mess or noise are less of a nuisance there. Sometimes, if the laundry is found in the basement, a laundry chute collects dirty laundry from the upper floors of the house. The basement can contain all of these objects and still be considered to be "unfinished", as they are either mostly or entirely functional in purpose. In this case

Loy ploughing was a form of manual ploughing carried out in Ireland using a form of spade called a loy. It was done on very small farms where horses could not be afforded or did not have enough work, and on very hilly ground where horses could not work. It was used on poorer land until the 1960s. This suited
2412-424: The crawl space is debatable. In areas with humid summers, during the summer months, the air vented into a crawl space will be humid, and as it enters the crawl space, which has been cooled naturally by the earth, the relative humidity of the air will rise. In those cases, crawl space vents can even increase the humidity level of a crawl space and lead to condensation on cool surfaces within, such as metal and wood. In
2479-422: The damp ground, water vapour (entering from crawl space vents), and moisture seeping through porous concrete can create a perfect environment for mold/mildew to form on any surface in the crawl space, especially cardboard boxes, wood floors and surfaces, drywall and some types of insulation. Health and safety issues must be considered when installing a crawl space. As air warms in a home, it rises and leaves through
2546-536: The floor above in a small basement. A series of these supports may be necessary for large basements; many basements have the support columns exposed. Since warm air rises, basements are typically cooler than the rest of the house. In summer, this makes basements damp, due to the higher relative humidity . Dehumidifiers are recommended. In winter, additional heating, such as a fireplace or baseboard heaters may be required. A well-defined central heating system may minimize this requirement. Heating ducts typically run in
2613-474: The floor's ceiling should be enough above ground to provide nearly full-size windows. Some daylight basements are located on slopes, such that one portion of the floor is at-grade with the land. A walk-out basement almost always results from this. Most daylight basements naturally result from raised bungalows and at-grade walk-out basements. However, there are instances where the terrain dips enough from one side to another to allow for 3/4 to full-size windows, with
2680-488: The foundation drains. If the water table outside the basement is above the height of the basement floor, then the foundation drains or the weeping tiles outside the footings may be insufficient to keep the basement dry. A sump pump may be required. It can be located anywhere and is simply in a well that is deeper than the basement floor. Even with functioning sump pumps or low water tables, basements may become wet after rainfall, due to improper drainage. The ground next to

At-grade walk-out basements on the door-side are often used as livable space for the house, with the buried portion used for utilities and storage. A subbasement is a floor below the basement floor. In the homes where there is any type of basement mentioned above, such as a look-out basement, all of the volume of the subbasements from floor to ceiling are located well below ground. Therefore, subbasements have no windows nor an outside door. In

2814-415: The foundation must be below the frost line. Unless constructed in very cold climates, the frost line is not so deep as to justify an entire level below the ground, although it is usually deep enough that a basement is the assumed standard. In places with oddly stratified soil substrata or high water tables , such as most of Florida , Texas , Oklahoma , Arkansas , and areas within 50 miles (80 km) of
2881-413: The foundation; only the basement walls are. If there are posts supporting a main floor beam to form a post and beam system, these posts typically go right through the basement floor to a footing underneath the basement floor. It is the footing that supports the post and the footing is part of the house foundation. Load-bearing wood-stud walls rest directly on the concrete floor. Under the concrete floor
2948-522: The frost line. An underground crawl space (as the name implies) is a type of basement in which one cannot stand up—the height may be as little as one foot (30 cm), and the surface is often soil. Crawl spaces offer a convenient access to pipes, substructures and a variety of other areas that may be difficult or expensive to access otherwise. While a crawl space cannot be used as living space, it can be used as storage, often for infrequently used items. Care must be taken in doing so, however, as water from

Subbasements are much more common in larger structures, such as commercial buildings and larger apartment buildings, than they are in single family homes. It is common for skyscrapers to have multiple subbasements. Building
3082-425: The inside or the outside walls of a basement. When waterproofing existing basements it is much cheaper to waterproof the basement on the inside. Waterproofing on the outside requires the expense of excavation, but does offer a number of advantages for a homeowner over the long term. Among them are: The unfinished design, found principally in spaces larger than the traditional cellar, is common in residences throughout
3149-407: The introduction of metal spades manual labor was less efficient at moving earth , with picks being required to break up the soil in addition to a spade for moving the dirt. With a metal tip, a spade can both break and move the earth in most situations, increasing efficiency. A classic spade, with a narrow body and flat (or near flat) tip is suited for digging post holes, and is not to be confused with
3216-400: The last decade. Dry rot and other conditions detrimental to buildings (particularly wood and timber structures) can develop in enclosed spaces. Providing adequate ventilation is thought to reduce the occurrence of these problems. Crawl space vents are openings in the wall which allow air movement. Such vents are usually fitted with metal grating , mesh , or louvers which can block

3551-406: The possibility of the upper floors collapsing into the basement; on the other hand, they may be required in tornado-prone areas as a shelter against violent winds. Adding a basement can also reduce heating and cooling costs as it is a form of earth sheltering , and a way to reduce a building's surface area-to-volume ratio . The housing density of an area may also influence whether or not a basement
3618-442: The rest of the house; refrigerators, stand-alone freezers, and microwaves (the first and the second being also sometimes used as supplementary storage units in an unfinished basement); and sports pennants and/or other types of posters which are attached to the walls. As the description suggests, this type of basement, which also might be called "half-finished", is likely used by teenagers and children. The entire family might utilize

Basements are much easier to construct in areas with relatively soft soils and may be avoided in places where the soil is too compact for easy excavation. Their use may be restricted in earthquake zones, because of
3819-400: The space has been designed, either during construction or at a later point by the owners, to function as a fully habitable addition to the house. Frequently most or all of the basement is used as a recreation room or living room, but it is not uncommon as well to find there (either instead of or alongside the living/recreation room) a guest bedroom or teenager's room, a bathroom, a home office,

In areas where storm and sanitary sewers are combined, and there is the risk of flooding and sewage backing up, backwater valves in all basement drains may be mandated by code and definitely are recommended even if not mandated. The main water cut-off valve is usually in the basement. Basements often have "clean outs" for
4288-518: The walls of a finished basement are typically insulated to the floor with vapor barriers to prevent moisture transmission. However, a finished basement should avoid wood or wood-laminate flooring, and metal framing and other moisture resistant products should be used. Finished basements can be costly to maintain due to deterioration of waterproofing materials or lateral earth movement etc. Below-ground structures will never be as dry as one above ground, and measures must be taken to circulate air and dehumidify
4355-502: The winter, crawl space vents should be shut off entirely, to keep out the cold winter air which can cool hot water pipes, furnaces, and water heaters stored within. During rainy weather, crawl space vents bring wet air into the crawl space, which will not dry the space effectively. Structurally, for houses, the basement walls typically form the foundation. In warmer climates, some houses do not have basements because they are not necessary (although many still prefer them). In colder climates,
