2、ear of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in July 2014.1.
3、 Scope1.1 This guide describes the use of a high solids content,cold liquid-applied elastomeric waterproofing membrane thatmeets the performance criteria specified in Specification C836,subject to intermittent hydrostatic pressure in a waterproofingsystem intended for installation on vertical cast-i
4、n-place con-crete surfaces.1.2 The committee with jurisdiction over this standard is notaware of any comparable standards published by other orga-nizations.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not b
5、e exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility o
6、f the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

General6.1 GeneralThe major components to be considered for abelow grade building wall waterproofing system are thestructural wall or substrate to be waterproofed, waterproofingmembrane, membrane protection, drainage, and backfill. Ad-ditional
12、 components to be considered are membraneterminations, penetrations, joints, and thermal insulation.6.2 CompatibilityIt is essential that all components andcontiguous elements be compatible, and that they be coordi-nated to form an integrated waterproofing system.6.3 ContinuityIt is essential that t
13、he waterproofingmembrane, including all joints and transitions, is continuous.1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.22 on Water-proofing and Dampproofing Systems.Current edition approved July 1, 20

United States1Special attention must be paid to changes in plane, transitionsfrom one substrate to another, terminations
16、, and abuttingwaterproofing systems. Expansion and control joints in abut-ting vertical and horizontal surfaces must maintain the conti-nuity of the system. It is recommended that, during systemdevelopment and documentation, isometric drawings be madeof three dimensional connections and transitions.
17、7. Substrate7.1 GeneralThe building wall substrate referred to in thisguide is reinforced, cast-in-place concrete.7.2 StrengthThe strength of concrete is a factor to beconsidered with respect to liquid-applied membranes so far asit relates to surface finish, bond strength, and continuingintegrity (a
18、bsence of cracks and other concrete defects thatcould affect the integrity of the membrane).7.3 Density and Moisture ContentThe density and mois-ture content of concrete when cured are interrelated. Exces-sively high moisture content can affect adhesion of the mem-brane to a substrate as moisture ma
19、y condense at the membraneto concrete interface and cause membrane delamination. Lowermoisture contents are achieved with the use of hard, densestone aggregate. This type of coarse aggregate will generallyprovide structural concrete with moisture content from 3 to 5%when cured. The concrete substrat
20、e should have a minimumdensity of 2100 kg/m3130 lb/ft3 and a maximum moisturecontent of 8% when cured.7.4 AdmixturesPolymeric, latex, or other organic chemi-cal based admixtures or modifiers can coat the concreteparticles and reduce the adhesion of the membrane to thesubstrate. If the concrete subst
21、rate will contain any admixtures,the membrane manufacturer should be consulted and shouldapprove the use of the membrane with the specific proposedadmixtures.7.5 Release and Curing AgentsForm release agents andform oils are often used to facilitate the removal of the concreteform work, and curing ag
22、ents are sometimes applied to thegreen (uncured) concrete surface. These chemicals can reducethe adhesion of the membrane to the concrete, and their useshould be coordinated with and be accepted by the membranemanufacturer. Form oils should not be used on areas to receivewaterproofing. If form oils
23、were used, sandblasting or otherapproved methods must be used to remove the form oils priorto waterproofing application.7.6 FinishThe structural wall should have a smooth formfinish. The surface should provide a mechanical bond for themembrane but not be so rough as to preclude achievingcontinuity o
24、f the membrane and the specified membranethickness across its surface. All fins, projections, tie rod holes,and honeycomb must be repaired. The removal of fins andsimilar projections is especially critical, because they causethin spots in the membrane that are easily punctured. Theconcrete surface a
