A water table is a projection of lower masonry on the outside of a wall, slightly above the ground, or at the top of a wainscot section of a wall (in this case also known as a sill).

Contents

It is both a functional and architectural feature that consists of a projection that deflects water running down the face of a building away from lower courses or the foundation. [1] [2] A water table may also be primarily decorative, as found near the base of a wall or at a transition between materials, such as from stone to brick. The top of the water table is often sloped or chamfered to throw off water. [3]

Often a damp course is placed at the level of the water table to prevent upward penetration of ground water. [4]

<span class="mw-page-title-main">Masonry</span> Building of structures from individual units of stone, bricks, or blocks

Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound and pasted together by mortar; the term masonry can also refer to the building units themselves. The common materials of masonry construction are bricks and building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades.

<span class="mw-page-title-main">Wall</span> Vertical structure, usually solid, that defines and sometimes protects an area

A wall is a structure and a surface that defines an area; carries a load; provides security, shelter, or soundproofing; or, is decorative. There are many kinds of walls, including:

<span class="mw-page-title-main">Stonemasonry</span> Creation of buildings, structures, and sculpture using stone

Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar and even the ancient lime mortar, to wall or cover formed structures.

<span class="mw-page-title-main">Brickwork</span> Masonry made of bricks and mortar

Brickwork is masonry produced by a bricklayer, using bricks and mortar. Typically, rows of bricks called courses are laid on top of one another to build up a structure such as a brick wall.

<span class="mw-page-title-main">Siding (construction)</span> Exterior cladding on building walls

Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable, more comfortable environment on the interior side. The siding material and style also can enhance or detract from the building's beauty. There is a wide and expanding variety of materials to side with, both natural and artificial, each with its own benefits and drawbacks. Masonry walls as such do not require siding, but any wall can be sided. Walls that are internally framed, whether with wood, or steel I-beams, however, must always be sided.

<span class="mw-page-title-main">Fireplace</span> Device for firing solid fuels in buildings

A fireplace or hearth is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.

<span class="mw-page-title-main">Ashlar</span> Finely dressed stone and associated masonry

Ashlar is finely dressed stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect.

<span class="mw-page-title-main">Masonry oven</span> Baking chamber made of fireproof brick, concrete, or stone

A masonry oven, colloquially known as a brick oven or stone oven, is an oven consisting of a baking chamber made of fireproof brick, concrete, stone, clay, or cob. Though traditionally wood-fired, coal-fired ovens were common in the 19th century, and modern masonry ovens are often fired with natural gas or even electricity. Modern masonry ovens are closely associated with artisan bread and pizza, but in the past they were used for any cooking task involving baking. Masonry ovens are built by masons.

<span class="mw-page-title-main">Quoin</span> Masonry blocks at the corner of a wall

Quoins are masonry blocks at the corner of a wall. Some are structural, providing strength for a wall made with inferior stone or rubble, while others merely add aesthetic detail to a corner. According to one 19th-century encyclopedia, these imply strength, permanence, and expense, all reinforcing the onlooker's sense of a structure's presence.

<span class="mw-page-title-main">Damp (structural)</span> Presence of unwanted moisture in the structure of a building

Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. Capillary penetration of fluid from the ground up through concrete or masonry is known as "rising damp" and is governed by the shape and porosity of the construction materials through which this evaporation-limited capillary penetration takes place. Structural damp, regardless of the mechanisms through which it takes place, is exacerbated by higher levels of humidity.

<span class="mw-page-title-main">Damp proofing</span> Type of moisture control in building construction

Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.

In architecture and masonry, the term set-off or off-set is given to the part of a wall or other architectural feature, which is exposed when the portion above is of a reduced thickness. In plinths, this is generally simply chamfered. In other parts of stonework, the set-off is generally concealed by a projecting string course. In parapets, where the upper part projects the lower, the break is generally hidden by a corbel. The portions of buttress caps which recede one behind another are also called sets-off. The term for a set-off near ground level is water table, often sloped at the top to throw off water.

<span class="mw-page-title-main">Mortar joint</span> Spaces between bricks filled with mortar

In masonry, mortar joints are the spaces between bricks, concrete blocks, or glass blocks, that are filled with mortar or grout. If the surface of the masonry remains unplastered, the joints contribute significantly to the appearance of the masonry. Mortar joints can be made in a series of different fashions, but the most common ones are raked, grapevine, extruded, concave, V, struck, flush, weathered and beaded.

<span class="mw-page-title-main">Gibbs surround</span> Architectural feature surrounding a door or window

A Gibbs surround or Gibbs Surround is a type of architectural frame surrounding a door, window or niche in the tradition of classical architecture otherwise known as a rusticated doorway or window. The formula is not fixed, but several of the following elements will be found. The door is surrounded by an architrave, or perhaps consists of, or is flanked by, pilasters or columns. These are with "blocking", where rectangular blocks stick out at intervals, usually alternating to represent half the surround. Above the opening there are large rusticated voussoirs and a keystone and a pediment above that. The most essential element is the alternation of blocking with non-blocking elements. Some definitions extend to including arches or square openings merely with alternate blocked elements that continue round the top in the same manner as the sides, as in the rectangular windows of the White House's north front basement level.

In military engineering, a ditch is an obstacle designed to slow down or break up an attacking force, while a trench is intended to provide cover to the defenders. In military fortifications the side of a ditch farthest from the enemy and closest to the next line of defence is known as the scarp while the side of a ditch closest to the enemy is known as the counterscarp.

<span class="mw-page-title-main">Rampart (fortification)</span> Defensive bank or wall surrounding a fortified site, such as a castle or settlement

In fortification architecture, a bank or rampart is a length of embankment or wall forming part of the defensive boundary of a castle, hillfort, settlement or other fortified site. It is usually broad-topped and made of excavated earth and/or masonry.
