Joints shall not exceed l0 mm (about 3/8") in thickness and this thickness shall be uniform throughout. The joints shall be raked out not less than l0mm (about 3/l8") deep when the mortar is green where pointing is to be done. When the brick surface are to be plastered, the joints shall be raked to a depth of 5 mm when the mortar is green, so as to provide good key to plaster
Joints. 5.04.03(a) Contraction Joints Transverse weakened-planed contraction joints shall be constructed at right angles to the curb line. When concrete curb and gutter is constructed adjacent to concrete pavement, the transverse joint spacing of the curb and gutter shall coincide with that of the concrete pavement. When concrete curb and gutter is constructed adjacent to asphalt pavement, transverse joints shall have a uniform spacing not exceeding 5m.The width of the contraction joint shall be 3 to 5 mm and a minimum depth of 65 mm.Contraction joints maybe sawed, hand-formed, or made by 3mm thick division plates in the formwork. Sawing shall be done early after the concrete has set to prevent the formation of uncontrolled cracking. The joints may be hand-formed either by (1) using a narrow or triangular jointing tool or a thin metal blade to impress a place of weakness into the plastic concrete, or (2) inserting 3mm thick steel strips into the plastic concrete temporarily. Steel strips shall be withdrawn before final finishing of the concrete. Where division plates are used to make contraction joints, the plates shall be removed after the concrete has set and while the forms are still in place. 5.04.03(b) Expansion (Isolation) Joints Expansion joints shall be constructed between the curb and abutting immovable structures, including catchbasin frames, abutting sidewalks, driveways, gutter outlets or any other structures where cracking is likely to occur.When the curb and gutter system is placed adjacent to the concrete pavement, longitudinal joints, as shown in the contract documents, shall be sawn between a curb and gutter system and concrete pavement. The joint shall be sealed with liquid joint sealer. All the work shall be according to City of Windsor Standard Specification S-9 Concrete and S-7 Concrete Pavement and Concrete Base.Expansion joint material shall be set in place before concrete placement begins and shall be supported by removable forms. Filler material for isolation joint shall be furnished in a single 12-20mm thick piece for the full depth and width of the joint and meet the requirements of OPSS.MUNI 1308, except that cork expansion fillers will not be accepted.Joint filler panels shall be set in a vertical position and, if for transverse joints, shall be set normal to the inside edge of the structure.Panels shall be pre-cut from a single piece to the shape of the cross-section as shown on the standard drawings, but so as to provide a 6mm recess...
Joints. To be grouted with cement mortar (2 : 1) or with asphalted bitumen to the proper consistency so as to thoroughly penetrate all the spaces and snatch the sand below. In case of asphaltum grouting care must be taken to sprinkle sand over the surface. When cement mortar is used in grouting the surface should be kept under water for at least 14 days.
Joints. Joints between sections of pipe and between pipe and fittings shall be threaded, flanged, or welded as specified. Except as otherwise specified, fittings 38 mm 1-1/2 inches and smaller shall be either threaded or socket welded, and fittings 50 mm 2 inches and larger shall be either flanged or butt welded. Pipe and fittings 32 mm 1-1/4 inches and larger installed in inaccessible conduits or trenches under concrete floor slabs shall be welded. Unless otherwise specified or indicated, connections to equipment shall be made with black malleable iron unions for pipe 38 mm 1-1/2 inches or smaller in diameter, and with flanges for pipe 50 mm 2 inches or larger in diameter.
Joints. All joints shall be standard, mortise and tennon, dowel, dovetail, and crosshalved. Nailed or glued butt joints will not be permitted. Screws, nails, etc. will be of standard iron or wire unless stated otherwise on drawing. Where mortise and tenon joints are used, tenons should fit the mortise exactly. Where screws show or a finished surface, these will be sunk, and the hold plugged with a wood plug of the same wood and grain of the finished surfaces, unless otherwise. Nails on finished surface will be neatly punched and the hole filled with wood filler to match the colour. UPHOLSTERY : This will be of first class standard workmanship with webbing, no sag springs, coiled springs, padding and filling as specified on drawing. Covering fabrics will be sewn, tufted, and corded as shown on the drawing.
Joints. Full depth transverse expansion joints shall be constructed perpendicular to the surface of the pathways at intervals not to exceed fifty (50') feet. Expansion joint material shall be one-half (1/2”) inch wide pre-molded expansion joints and shall be set ¼” below the surface of the pathway. Sealing of joints will not be required. One (1”) inch pre-molded expansion joints must be placed between the pathway and back-of-curb when pathway is constructed between the curb and building or other rigid structures. Sealing of joints will not be required. Transverse plane of weakness joints shall be true to line and grade, and shall be placed at four (4') foot intervals and shall be formed with a grooving tool or sawcut to match adjoining sidewalk. Planes of weakness joints shall be constructed to a depth of at least one (1”) inch and a width of 1/8 inch to ¼ inch. Sealing of joints will not be required.
