15、tates17. Reinforcement7.1 Reinforcement is required for built-up and modifiedbitumen membranes at transitions, such as internal and externalcorners and at static concrete construction joints and cracks.Reinforcement also is required where reinforcing bars, pipes,and conduits penetrate the membrane.

16、Separate reinforcementgenerally is not required for polymeric and vulcanized elasto-meric membranes.7.2 Reinforcement usually is installed before the membranebut may be applied over it. Refer to the membrane manufac-turer for details.7.3 The minimum reinforcement is one ply. Systems using amultiple

17、ply membrane usually require two or more reinforce-ment plies, whereas single ply modified bitumen systemsgenerally require one.7.4 When additional plies are used as reinforcement, theyshould extend at least 150 mm 6 in. beyond the corner orpenetration and each succeeding ply should extend 75 mm 3in

18、. beyond the previous ply.7.5 Where reinforcing bars penetrate waterproofing, such asat rock anchors and wall to slab transitions, they should besealed with reinforcing plies finger cut around the bars or liquidapplied membrane or both.7.6 Some manufacturers require cementitious cants or aliquid app

19、lied waterproofing or mastic fillet at reentrant angles,chamfered external corners, and other special conditions to beimplemented during construction. These should be indicatedon project details.7.7 Details should recognize the normal sequencing ofconstruction. Foundation walls may be cast before or

20、 afterslabs on grade. Structural slabs are cast after walls. Water-proofing of individual elements frequently follows thissequence, for example, walls are waterproofed before thestructural slab is cast. The resultant cold joints may bedynamic.8. Penetrations8.1 Flashing at penetrations should accomm

21、odate differen-tial movement between the slab and the pipe, conduit, or drain.For built-up and modified bitumen membranes, lead reinforc-ing is recommended where pipes or drains are installed insleeves but is optional where they are cast into the wall or slab.Cast iron drains, cast into the slab wit

22、h flanges flush with orslightly below the slab, are preferred. Additional plies ofreinforcement should be installed at drains.8.2 Wearing courses on plaza decks move differentiallyfrom the structural slab. To prevent damage to the drainagesystem or flashing rupture from this movement, drains shouldb

23、e installed in the structural slab with inlets in the wearingcourse divorced from the drain body.9. Expansion Joints9.1 Structural expansion joints should be designed to permitindependent movement of structural elements on each side ofthe joint. Control joints should be located to permit non-reversi

24、ble movement and may be dynamic. The size andlocation of expansion and control joints should be determinedby the structural engineer. Expansion joint covers should bedesigned to maintain continuity at all changes in plane. Theyshould be designed to prevent displacement when subjected towater pressur

25、e. Where they occur in elevated slabs, they shouldbe raised above the surface. Control joints are not detailed asexpansion joints but should be reinforced in all membranesystems.10. Structural Items10.1 Water stops, keyways, and other structural elementsthat are frequently installed in construction

26、and control jointsare not indicated on the details.11. Mud Mats11.1 Mud mats are cast on the subgrade to support water-proofing. Protection boards and tamped sand beds may beacceptable alternates with some manufacturers.12. Planters, Bench, and Equipment Supports12.1 Waterproofing membranes on horiz

27、ontal surfacesshould be carried under planters and supports without inter-ruption. Such items should be installed on the concreteprotection slab. Waterproofing of planters should be indepen-dent of the slab waterproofing.13. Explanatory Notes13.1 Fig. 1Standard details for adhered sheet waterproof-i

28、ng.13.2 Fig. 2This detail is applicable to tunnels and condi-tions where the width of excavations is limited.Alternately, themud mat may be omitted and waterproofing applied to the topof a structural slab and turned down to the toe. Then,waterproofing is covered with a cementitious wearing course.13

30、er or applicator are required to indicatethe assembly of the overlapping plies.13.7 Fig. 9 and Fig. 10Waterproofing should not beterminated below grade. Even when a reglet is used toterminate the sheet, or a cap flashing is installed in a reglet,water can migrate behind the sheet through cracks abov

31、e thereglet. Because most of the adhered sheet waterproofingmaterials are subject to degradation by ultraviolet light or heat,it is recommended that foundation waterproofing be carried toa brick shelf or haunch below grade and terminated. This willpermit it to be protected until cladding above is in

32、stalled.Counterflashing should be carried at least 200 mm 8 in. abovegrade behind a permanent cladding. Suitable cladding materi-als at or below grade include granite and similar low permeablestones, SW grade brick, precast concrete, cement plaster andD5898/D5898M 96 (2013)2corrosion-resistant metal

33、. The dotted line indicates that adense, impervious protection board is required under themasonry.13.8 Fig. 11 and Fig. 12These details are applicablewhere foundation walls are extended 300 mm 12 in. or moreabove grade. Waterproofing should be extended to a brick shelfwhere the top edge can be seale

34、d and protected by cap flashing.The membrane is promptly covered with a protection layer.Finishes, such as stucco or insulation and stucco, are appliedover the protection layer.13.9 Fig. 13 and Fig. 14These details are applicable towalls or parapets supported by the slab where the verticalelement is

35、 supported on the slab and the joint is not dynamic.Horizontal waterproofing is elevated 37 mm 1.5 in. above theslab on a cast-in-place cant, 100 mm 4 in. wide. A compress-ible filler is required between wearing surface assemblies andthe protection layer over the membrane. Protection board isrequire

36、d between the membrane and the metal flashing. It isrecommended that the flashing terminate in a receiver to permitinstallation of the metal cap flashing after masonry is com-pleted and to provide a suitable surface for the caulking. Fig.14 depicts a method of concealing the base flashing.13.10 Fig.

37、 15This detail is applicable to expansion jointsin the elevated slab. The joint is raised as in Fig. 13. Expansionjoint covers in the plane of the elevated slab should be avoided.A compressible closed cell neoprene tube or proprietaryformed member is used to permit the membrane to flex. Aplastic, ne

38、oprene, butyl or polymer-modified bitumen ham-mock is installed to support the tubing, act as a bitumen stopand as a vapor retarder. Although insulation reduces the heatloss, it may lower the temperature of the vapor retarder belowthe dewpoint temperature. The first ply over the tube should bean ela

39、stomeric material similar to the hammock and disbondedfrom the tube. One or more plies of elastomeric material thenare applied extending over the slab. The alternate proprietaryformed member does not require a hammock. While theelimination of the hammock reduces the redundancy of thejoint cover, it

40、does offer more convenient leak detectability. Agutter under the expansion joint is optional with the hammocksystem but strongly recommended without it.FIG. 1 Standard Details for Adhered Sheet WaterproofingD5898/D5898M 96 (2013)313.11 Fig. 16This detail is applicable to walls or parapetsthat are no

Drain strainers and their frames,however, should be designed to support anticipated vehicularloads of snow removal equipment, maintenance vehicles, fireengines, and the l

44、ike. Lead, if used, should be carried into thedrain bowl. Membrane and reinforcing should lap drain flanges100 mm 4 in. and be secured with clamping rings. Sedimentbuckets are recommended where wearing surfaces are waterpermeable and where debris is expected.14. Keywords14.1 expansion joints; flashi
