Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions

13、 as appropriate. In all cases only the current versionof the standard as published by ASTM is to be considered the official document.Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.5. Drawings5.1 This guide is not all inclusive. The d

14、esigner should detail all typical and special conditions on the project, paying particularattention to transitions in plane and intersection of different details. The applicator should provide shop drawings of each conditionto confirm field conditions and to verify his understanding of the design in

15、tent.5.2 Waterproofing membranes and reinforcement are indicated on the figures as a single thick line, regardless of the number ofplies.5.3 Protection layers have been omitted for clarity. See Section 6.6. Protection6.1 Protection materials are required over all waterproofing to prevent damage from

16、 backfill, reinforcing chairs, andconstruction traffic, unless the membrane system incorporates an integral protection layer. Protection also is required wheremembranes terminate above grade and may be exposed to ultraviolet light.6.2 Materials for protection include: asphalt composition boards, pla

17、stic drainage panels, low density expanded polystyreneboards, and extruded polystyrene insulation. Low density expanded polystyrene boards and some types of plastic drainage panelsare not suitable for protection on horizontal surfaces. Protection materials are loose-laid on horizontal membranes and

18、attached tovertical membranes with compatible adhesives. They should be installed as soon as possible after the membrane, or each portionof it, is completed or water tested.7. Reinforcement7.1 Reinforcement is required for built-up and modified bitumen membranes at transitions, such as internal and

19、external cornersand at static concrete construction joints and cracks. Reinforcement also is required where reinforcing bars, pipes, and conduitspenetrate the membrane. Separate reinforcement generally is not required for polymeric and vulcanized elastomeric membranes.7.2 Reinforcement usually is in

20、stalled before the membrane but may be applied over it. Refer to the membrane manufacturerfor details.7.3 The minimum reinforcement is one ply. Systems using a multiple ply membrane usually require two or more reinforcementplies, whereas single ply modified bitumen systems generally require one.7.4

21、When additional plies are used as reinforcement, they should extend at least 150 mm (6 in.)6 in. beyond the corner orpenetration and each succeeding ply should extend 75 mm (3 in.)3 in. beyond the previous ply.7.5 Where reinforcing bars penetrate waterproofing, such as at rock anchors and wall to sl

22、ab transitions, they should be sealedwith reinforcing plies finger cut around the bars or liquid applied membrane or both.7.6 Some manufacturers require cementitious cants or a liquid applied waterproofing or mastic fillet at reentrant angles,chamfered external corners, and other special conditions

23、to be implemented during construction. These should be indicated onproject details.7.7 Details should recognize the normal sequencing of construction. Foundation walls may be cast before or after slabs on grade.Structural slabs are cast after walls. Waterproofing of individual elements frequently fo

24、llows this sequence, for example, walls arewaterproofed before the structural slab is cast. The resultant cold joints may be dynamic.8. Penetrations8.1 Flashing at penetrations should accommodate differential movement between the slab and the pipe, conduit, or drain. Forbuilt-up and modified bitumen

25、 membranes, lead reinforcing is recommended where pipes or drains are installed in sleeves but isoptional where they are cast into the wall or slab. Cast iron drains, cast into the slab with flanges flush with or slightly below theslab, are preferred. Additional plies of reinforcement should be inst

26、alled at drains.8.2 Wearing courses on plaza decks move differentially from the structural slab. To prevent damage to the drainage system orflashing rupture from this movement, drains should be installed in the structural slab with inlets in the wearing course divorcedfrom the drain body.9. Expansio

27、n Joints9.1 Structural expansion joints should be designed to permit independent movement of structural elements on each side of thejoint. Control joints should be located to permit non-reversible movement and may be dynamic. The size and location of expansionand control joints should be determined

28、by the structural engineer. Expansion joint covers should be designed to maintaincontinuity at all changes in plane. They should be designed to prevent displacement when subjected to water pressure. Where theyoccur in elevated slabs, they should be raised above the surface. Control joints are not de

29、tailed as expansion joints but should bereinforced in all membrane systems.10. Structural Items10.1 Water stops, keyways, and other structural elements that are frequently installed in construction and control joints are notindicated on the details.D5898/D5898M 96 (2005)1211.

Planters, Bench, and Equipment Supports12.1 Waterproofing membranes on horizontal surfaces should be carried under planters and supports without interrupti

31、on. Suchitems should be installed on the concrete protection slab. Waterproofing of planters should be independent of the slabwaterproofing.13. Explanatory Notes13.1 Fig. 1Standard details for adhered sheet waterproofing.13.2 Fig. 2This detail is applicable to tunnels and conditions where the width

32、of excavations is limited. Alternately, the mudmat may be omitted and waterproofing applied to the top of a structural slab and turned down to the toe. Then, waterproofing iscovered with a cementitious wearing course.13.3 Fig. 3Slab with mud mat.13.4 Fig. 4Footing with mud mat.13.5 Fig. 5This detail

33、 is applicable to conditions where there is no hydrostatic head below the slab.13.6 Fig. 6, Fig. 7, and Fig. 8Where internal and external vertical corners meet horizontal surfaces, isometric drawingsprepared by the designer or applicator are required to indicate the assembly of the overlapping plies

34、.13.7 Fig. 9 and Fig. 10Waterproofing should not be terminated below grade. Even when a reglet is used to terminate thesheet, or a cap flashing is installed in a reglet, water can migrate behind the sheet through cracks above the reglet. Because mostof the adhered sheet waterproofing materials are s

35、ubject to degradation by ultraviolet light or heat, it is recommended thatfoundation waterproofing be carried to a brick shelf or haunch below grade and terminated. This will permit it to be protected untilcladding above is installed. Counterflashing should be carried at least 200 mm (8 in.)8 in. ab

36、ove grade behind a permanentcladding. Suitable cladding materials at or below grade include granite and similar low permeable stones, SW grade brick, precastconcrete, cement plaster and corrosion-resistant metal. The dotted line indicates that a dense, impervious protection board isrequired under th

It is recommendedthat the flashing terminate in a receiver to permit installation of the metal cap flashing after masonry is completed and to providea suitable

41、 surface for the caulking. Fig. 14 depicts a method of concealing the base flashing.13.10 Fig. 15This detail is applicable to expansion joints in the elevated slab. The joint is raised as in Fig. 13. Expansion jointcovers in the plane of the elevated slab should be avoided.Acompressible closed cell

42、neoprene tube or proprietary formed memberis used to permit the membrane to flex. A plastic, neoprene, butyl or polymer-modified bitumen hammock is installed to supportthe tubing, act as a bitumen stop and as a vapor retarder. Although insulation reduces the heat loss, it may lower the temperatureof

43、 the vapor retarder below the dewpoint temperature. The first ply over the tube should be an elastomeric material similar to thehammock and disbonded from the tube. One or more plies of elastomeric material then are applied extending over the slab. Thealternate proprietary formed member does not req

44、uire a hammock. While the elimination of the hammock reduces the redundancyof the joint cover, it does offer more convenient leak detectability. A gutter under the expansion joint is optional with the hammockFIG. 4 Footing with Mud MatFIG. 5 Footing with Raised SlabD5898/D5898M 96 (2005)15system but
