60
Q

Dampproofing

A

Control of moisture that is not under
hydrostatic pressure.
Dampproofing should not be used on elements below the water table; these call for waterproofing.
Dampproofing coatings are always applied on the positive side, or wet side,

61
Q

hydrostatic pressure

A

At its simplest, hydrostatic pressure is the pressure created by standing or resting (“static”) water (“hydro”). (While concrete is a relatively solid material when dry, it isn’t technically solid; As concrete dries, water vapor from the original concrete mixture exits the slab, creating small capillary networks until properly sealed. For a concrete slab to be impacted by hydrostatic pressure, it must be below the water table on the site or intrude into a natural water pathway.)

62
Q

admixture

A

Various admixtures can be added to concrete to make it water repellent, such as the salts of fatty acids, mineral oil, and powdered iron. These may reduce the strength of the concrete, but they make it much less permeable to water

63
Q

cementitious coatings

A

Mortar coatings are often used over very rough walls to pro- vide a smooth surface for the installation of other dampproofing materials,

64
Q

bituminous coatings

A

These are asphalt or coal-tar pitch materials applied to the exterior side of the foundation wall. They can be brushed or sprayed on, can be applied either hot or cold (depending on the type), and should be applied to smooth surfaces. These coatings will not seal cracks that develop after they are applied.

65
Q

membranes

A

Membranes are typically used for waterproofing walls subject to hydrostatic pressure because their cost and the difficulty of applying them is not usu-
ally warranted for simple dampproofing.

66
Q

plastics

A

Silicone and polyurethane coatings are available, but they are usually reserved for above-grade dampproofing.

67
Q

Waterproofing

A

is the control of moisture and water that is subject to hydrostatic pressure. This may include protecting parts of structures that are below the water table. Waterproofing is a more difficult technical problem than dampproofing because of the effect of the water pressure and the need to create
a continuous seal over walls, slabs, and joints in the structure.

In addition to the waterproofing and protection board, a foundation waterproofing system may include a geotextile or drainage board to relieve hydrostatic pressure against the wall insulation, as called for by
the climate zone and local code requirements.

68
Q

Negative side watetproofing

A

applied after the element is in place, but to the side of the element that is not exposed to water, such as the interior of a foundation wall

69
Q

positive side waterproofing

A

placed on the side of the element exposed to water-the exterior of a foundation wall, for example-after the element is in place

70
Q

Blind side waterproofing

A

applied before the element is in place, such as on a shored excavation against which a concrete foundation wall will be poured.

71
Q

Sheet membrane

A

Sheet membranes may be loosely applied and attached to nailing strips, but more effective systems are adhered to the foundation on the positive side.

72
Q

Fluid-applied Systems

A

These are applied in liquid form to provide a continuous, seamless membrane. These systems are applied on the positive
side.

73
Q

vapor retarder

A

material used to slow the transmission or diffusion of water vapor between spaces. Vapor retarders are not themselves insulation, but they play an important role in preserving the effectiveness of other insulating materials.
Vapor retarders should be placed on the warmer inside of the insulation

74
Q

Vapor diffusion

A

movement of water molecules through vapor-permeable materials

75
Q

permeance

A

property of a material that prevents water vapor from diffusing through it

76
Q

Class I perm rating

A

vapor impermeable - materials rating less than or equal to 0.1

77
Q

Class II perm rating

A

semi-impermeable - materials rating 0.1 and less than or equal to 1.0,

78
Q

Class III perm rating

A

permeable - materials rating greater than 1 or equal to 10

79
Q

barrier wall system

A

cladding serves as the exterior finish, protects the building from the elements and prevents condensation from entering the building. A solid, multi-wythe masonry wall or an exterior insulation and finish system (EIFS) applied directly to the structural wall are examples.

80
Q

rain srcreen wall

A

cladding is separated from the waterproof and airtight barriers with an air space cavity. Drainage plane of a WRB applied on the out- side of insulation prevents moisture that penetrates cladding from entering building and directs it back to the exterior with flashing, weep holes, etc… Insulation is located inside the drainage plane. Moisture barrier be may either air permeable or impermeable, depending on the climate, interior environmental conditions etc..

81
Q

Rock wool

A

manufactured by melting basalt or oilier rocks in a high-temperature furnace and then spinning the molten mate- rial into long fibers.

82
Q

Slag wool

A

manufactured from iron ore blast furnace slag using similar production methods. Slag wool accounts for about 80% of fill products produced by the mineral wool industry. It is formed into batts, blankets, and loose-fill material, and is used in applications similar to those of fiberglass.

83
Q

Cellulose insulation

A

made from 80% to 100% recycled paper combined with a fire-retardant additive. For loose-fill applications, a binder is added to prevent settling. Cellulose is used for loose-fill attic insulation as well as dry blown-in and wet-spray applications.

84
Q

Fiberglass insulation

A

sometimes used as loose fill, but is more commonly formed into batts, with or without a paper facing

85
Q

Batt insulation

A

This material is usually mineral fiber or glass fiber. In addition to providing a means of installation and holding the insulation in place, the kraft paper also serves as a vapor retarder.

86
Q

Board insulation

A

made from a variety of organic or inorganic materials formed into rigid boards

87
Q

Expanded polystyrene (EPS)

A

closed-cell material manufactured by mixing unexpanded polystyrene beads containing liquid pentane and a blowing agent. The spaces between the beads can absorb water, so a vapor retarder is needed if moisture migration is a concern.

88
Q

Extruded polystyrene (XPS)

A

is a closed-cell material manufactured by mixing polystyrene pellets with various chemicals and then introducing a blowing agent.

89
Q

Sprayed foam insulation

A

Sprayed foam has an excellent R-value with the added advantages of conforming to the shape of the cavity and sealing all cracks and openings thoroughly.

90
Q

emissivity

A

also called emittance, a measure of how much energy is emitted
