16、3 Do not expose membrane and accessories to a constanttemperature in excess of 82C (180F).8. Substrate Preparation8.1 The following items should be addressed in Division 3of the project specification.8.1.1 Remove from the substrate any laitance, loose aggre-gate, sharp projections, grease, oil, exce

Refer to Guide D 5295 for substratepreparation.8.1.2 Prepare all controlled and uncontrolled (cracks) jointsas recommended by the owner, producer, system supplier, orinstaller.8.1.3 The producer or

18、 system supplier of sheeting shallspecify types of substrates that would be acceptable for usewith the sheet bonding adhesive, splicing adhesive, and lapsealant. Information regarding acceptability of substrate mate-rials with other components utilized in the system is availablefrom suppliers of ind

19、ividual components.8.1.4 Concrete curing agents, other than water, are subjectto acceptance by the producer or system supplier.9. Installation of Sheets9.1 Deliver the sheets to the substrate in good condition.Handle the materials with care so as not to damage the sheets.9.1.1 Use care and diligence

20、 during installation to avoiddamaging the substrate and sheet.9.1.2 Start the sheet installation at the low point of the deckor wall and work to the termination point.9.1.3 Field seams shall be perpendicular or parallel with thedirection of water flow. Avoid field seams that oppose thedirection of w

21、ater flow.9.1.4 Follow appropriate details in Guide D 5898.9.2 Unroll or unfold the sheet and visually inspect forphysical damage prior to setting into location and performingthe attachment to the substrate and the field seaming betweensheets. Allow sheets to relax for a minimum of12 h. (Specifiersh

22、ould consult manufacturer for recommendation). (Use orremoval of questionable sheets shall be as agreed upon byproducer or system supplier, installer, and owners representa-tive). Do not permanently install protection board until allareas of question and other defects are resolved.9.3 Align the shee

23、t in its proper location maintaining arecommended splice overlap to the adjacent sheet. (Specifiershould consult manufacturer for splice width recommenda-tion). Fold back the area to be adhered, making a rounded edge.Use temporary ballast of sand bags or bias ply tires asnecessary to hold the horizo

24、ntal membrane in position. Re-move foreign matter like sand, dirt, twigs, and so forth, whichmay have lodged under the sheet. Where dirt has contaminatedthe surface, clean the sheet in accordance with the manufac-turers recommendations.9.4 Horizontal Installation Procedure for Adhesively Bond-ing Sh

25、eet to Substrate:9.4.1 Fold back one-half of the sheet, apply bonding adhe-sive continuously to the exposed substrate and the back of theexposed folded sheet at the producer or system suppliersrecommended rate. Do not apply bonding adhesive to theperimeter splice areas (recommended width of 15 cm (6

26、 in.) ofthe sheet.9.4.2 Allow the bonding adhesive to dry (sufficient solventhas evaporated) to the point where it is still tacky, but will notstick to the finger when touched lightly.9.4.3 Carefully roll the sheet into the applied adhesive whilemaintaining a rounded leading edge, in a manner that m

27、ini-mizes voids and wrinkles. Keep the sheet even and continuerolling until the sheet is adhered.9.4.4 Apply positive pressure to adhered areas to obtaincontact between membrane and substrate. Use a stiff broom orlarge roller with rounded edges to embed the membrane intothe applied adhesive.9.4.5 Fo

28、ld back the unbonded portion of the sheet to exposethe unattached portion of the sheet.9.4.6 Repeat steps 9.4.1 through 9.4.4, be sure that noadhesive is applied on the perimeter splice areas of the sheet.9.5 Vertical Installation Procedure for Adhesively BondingSheet to Approved Substrate:9.5.1 Fan

29、fold the membrane onto itself at the foundationsfooting and fully adhere the membrane vertically by section orhang the membrane with the splice running either vertically(bottom to top) or horizontally. If horizontally, work from thebottom up for shingled splices.9.5.2 Fold back one-half of the sheet

30、, apply bonding adhe-sive continuously to the substrate and the back of the foldedsheet and repeat procedure or completely to the back of thesheet at the recommended rate. Do not apply bonding adhesivein the splice area.9.5.3 Allow the bonding adhesive to dry (sufficient solventhas evaporated) to th

31、e point where it is still tacky, but will notstick to the finger when touched lightly.9.5.4 Carefully roll the sheet into the applied adhesive whilemaintaining a rounded leading edge or hang the membraneagainst the coated substrate in a manner that minimizes voidsand wrinkles. Keep the sheet even an

32、d continue rolling untilthe sheet is adhered.9.5.5 Apply positive pressure to adhered areas to attempt toobtain total contact between the membrane and substrate. Usea stiff brush or large roller with rounded edges to embed themembrane into the applied adhesive.9.6 Make field seams with producer or s

33、ystem suppliedsplicing systems. Prior to applying splicing adhesives to thewaterproofing sheets at the job site, clean the splice areathoroughly with splice cleaner dispensed from underwriterslaboratory (UL) pump cans using clean natural fiber cloth.D 5843 95 (2006)29.6.1 Apply the splice cleaner, p

34、rimer, and splicing adhesiveand allow for open time as recommended by producer orsystem supplier.9.6.2 Apply the in-the-seam sealant a minimum of 1.2 cm(12 in.) from the unexposed edge (if required by producer orsystem supplier for additional protection at splice intersec-tions).9.6.3 Join the matin

35、g surfaces carefully for a uniformcontact.9.6.4 Use a steel hand roller with rounded edges to applypositive pressure to the splice. Run the hand roller across theseam, from the inside of the top sheet to the edge of the fieldsplice to work out air bubbles.9.6.5 Inspect the outside edge for fishmouth

36、s. Where fish-mouths exist, cut the sheet to allow it to lay flat. Apply a patchof sheet material to the cut that extends a minimum of 15 cm(6 in.) in all directions beyond the defect in accordance withsplicing procedures noted in 9.6.1 through 9.6.4.9.6.6 After cleaning the seam edge with splice cl

37、eaner,apply and feather lap-seam sealant by the end of each dayswork. Inspect lap-seam sealant for continuous contact withboth sheets.9.6.7 Complete all field seams and secure and make water-tight all terminations by the end of each work day.9.7 Flashings, Terminations, Tie-Ins, and Expansion Joints

38、:9.7.1 Flashings and termination should extend a minimumof 20 cm (8 in.) above the grade.9.7.2 Flash penetrations inside and outside corners usingseparate uncured flashing materials.9.7.3 Secure the membrane edge to the substrate by using atermination bar or reglet when stopping the membrane and use

39、counterflashing when extending the membrane above thegrade.9.7.4 Consult the producer or system supplier for recom-mended tie-ins.9.8 Take precautions necessary to provide protection of thewaterproofing system before the end of the day.9.8.1 The loose edge of the sheet shall have a watertight sealto

40、 the substrate to prevent water from penetrating any com-pleted section of the waterproofing system.9.8.2 Do not abuse completed sections by subsequent ma-terial handling operations and traffic.9.8.3 Temporary protection of the membrane shall be pro-vided at the end of each days work with a minimum

41、3 mm (18in.) protection board.9.8.4 Apply by loose laying or spot bonding a minimum 3mm (18 in.) protection board over the membrane after qualityassurance (QA) items are addressed.10. Quality Assurance10.1 The producer or system supplier with the applicatorshall inspect splices, flashed details, and

42、 terminations duringthe application to verify that the sheet system is installed inaccordance with the producer or system suppliers specifica-tions.10.2 Flood test horizontal waterproofing in accordance withGuide D 5957. Repair any leaks with a surface splice thatextends a minimum of 15 cm (6 in.) p
