NOTE: This guide specification covers the requirements for sheet-applied elastomeric wateroofing.

Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.

Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).

Use of electronic communication is encouraged.

Brackets are used in the text to indicate designer choices or locations where text must be supplied by the designer.

NOTE: This guide specification is intended for use where local practice and experience indicates that protection against hydrostatic pressure or conditions of excessive dampness can be achieved by using elastomeric waterproofing. Typical applications include but are not limited to wall and foundation waterproofing, waterproofing promenades and parking decks, waterproofing beneath shower pans, kitchens, toilet facilities, janitorial rooms, and indoor swimming pools.

NOTE: Where concrete vault magazines are designed below ground, provide butyl rubber, or elastomeric composite, thermoplastic waterproof sheeting.

NOTE: On the drawings, show:

1. Extent of membrane waterproofing, substrates, termination details,termination details, flashing, and counterflashing, pipe and conduit penetrations, and junctions at walls and floors.

NOTE: This paragraph is used to list the publications cited in the text of the guide specification. The publications are referred to in the text by basic designation only and listed in this paragraph by organization, designation, date, and title.

Use the Reference Wizard's Check Reference feature when you add a RID outside of the Section's Reference Article to automatically place the reference in the Reference Article. Also use the Reference Wizard's Check Reference feature to update the issue dates.

References not used in the text will automatically be deleted from this section of the project specification when you choose to reconcile references in the publish print process.

NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.

A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractor’s Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.

For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the "G" designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO" for District Office (Engineering Division or other organization in the District Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project Office. Codes following the "G" typically are not used for Navy, Air Force, and NASA projects.

Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.

NOTE: When waterproofing will be installed indoors protected from the weather, delete the bracketed requirements for outdoor environmental conditions. Also, in geographical areas where the specifier determines it is routine to utilize artificial means of maintaining the surface and ambient temperatures above 4 degrees C 40 degrees F, include the conditions for waiver in the project specifications.

NOTE: Where concrete vault magazines are designed below ground, specify membrane sheeting. Do not apply primer or mastic until concrete has curred not less than 7 days, or as required by the manufacturer, remove all moisture, form oil and non- fungi curing agents.

NOTE: Specify a higher puncture resistance if the waterproofing will be subject to abuse. Commercial membranes are available which will exceed 890 N (200 pounds) in puncture resistance.

NOTE: Where recommended by the manufacturer for below ground membrane sheeting, provide securement strip at perimeter and at any penetrations(s) as well as any elevation changes.

NOTE: Always require protection material seperating waterproofing from fill material. Delete protection board option and require the polymeric grid option for earth covered magazines or facilities with routine ground water exposure

NOTE: NOTE: The fiberboard will not provide protection after it becomes wet. Bituminous-impregnated protection board must not be used in contact with polyvinyl chloride (PVC), which may be in composite membranes. Polystyrene is not compatible with petroleum products. The membrane and protection board must be compatible.

NOTE: A paragraph should be added to Section 03 31 00.00 10, CAST-IN-PLACE STRUCTURAL CONCRETE, Section 03 30 00.00 20 CAST-IN-PLACE CONCRETE or Section 03 40 00.00 40 CAST-IN-PLACE CONCRETE, to the effect that curing compound containing wax or oil should be removed prior to application of waterproofing.

NOTE: Delete requirements for cant strips if cant strips are not required.

NOTE: Suggestions for improvement of this specification will be welcomed using the Navy "Change Request Forms" subdirectory located in SPECSINTACT in Jobs or Masters under "Forms/Documents" directory or DD Form 1426. Suggestions should be forwarded to:
