The following series of steps show one method of forming a full perp joint. STEP 1 Apply a small amount of mortar to the header face of the brick. STEP 2 Use the trowel to make a smooth joint. Be careful when removing excess mortar. Smudged mortar doesnt look good! Full In this context, it means that the joint has no gaps or voids that will allow water penetration If your house or your friends house is built of brick, do you notice mortar smudged on the face of the wall? Look around for examples of clean walls and note how much better they appear. Make a list of different weather conditions (rain, snow, sun, etc) and write down how you think they could affect a bricklayers work. STEP 3 Angle the brick to smooth each STEP 4 Make sure that the joint is full. side of the joint. Building brickwork in the workshop is obviously different from producing a piece of work on site. The workshop is an indoor environment and therefore has none of the weather considerations that working outdoors brings with it.

Green Board. A gypsumboard with a tinted face paper, usually light green or blue, to distinguish special types of board; also denotes gypsumboard that is damp. Green Plaster. Wet or damp plaster. Grounds. A piece of wood, metal, or plaster attached to the framing to indicate the thickness of plaster to be applied. Gypsum. Fully hydrated calcium sulfate (calcium sulfate dihydrate). Gypsum Base. Gypsum lath used as a base for veneer plasters. Gypsumboard. A noncombustible board with gypsum core enclosed in tough, smooth paper. Type X. A gypsumboard specially formulated with high fire resistance for use in fire-rated assemblies. Hardwall. Gypsum neat base-coat plaster. Joint Treatment. Concealing of gypsumboard joints, usually with tape and joint compound. Joints: Butt. Joints in which gypsumboard ends with core exposed (usually in the direction of the board width) are placed together. Crown (High or Hump). Protrusion of joint compound from gypsumboard surface at a joint. Floating. (See Edges, Floating.) Keenes Cement. A dead-burned gypsum product that yields a hard, high-strength

Low initial cost Soldier pile or sheet pile walls. Consider combined soil slope and wall. Consider design items listed in Table 6.18. Use as part of permanent structure Diaphragm or pier walls. Diaphragm wall is the most common type of permanent wall. Subsurface conditions of deep, soft clay Struts or rakers that support a diaphragm or pier wall. Tieback capacity not adequate in soft clays. Subsurface conditions of dense, gravelly sands or clay Soldier pile, diaphragm wall, or pier wall. Sheet piles may lose interlock on hard driving. Subsurface conditions of overconsolidated clays Struts, long tiebacks, or combination of tiebacks and struts. High in-situ lateral stresses are relieved in overconsolidated soil. Lateral movements may be large and extend deep into the soil. Avoid dewatering Use diaphragm walls or possibly sheet pile walls in soft subsoils. Soldier pile wall is too pervious for this application. Minimize lateral movements of wall Use high preloads on stiff strutted
