Edit if required to include a manufacturer’s recommended system not described. Manufacturer’s data sheets on each product to be used, including:. Show including plans and details of cold fluid-applied two-component polyurethane waterproofing membrane system including membrane, penetration flashings, base flashings, and expansion joints size, flashing details, and attachment.

For each product specified, two samples, minimum size 6 inches mm square, representing actual product, thickness, color, texture and surfacing. Certify products meet or exceed specified requirements. Submit on site test reports of Substrate Moisture Content and Bond Strength test results as specified. Submit manufacturer warranty and ensure forms have been completed in Owner’s name and registered with manufacturer.

Company specializing in manufacturing the products system specified with a minimum of 20 years of documented experience with applications in the United States. Company specializing in performing the work of this section with a minimum of 3 years documented experience and approved by system manufacturer for warranted membrane installation. Membrane manufacturer shall provide the services of a competent field representative on-site to provide the following inspections:.

Job start inspection at the beginning of each phase kemperl the project, to review special detailing conditions and substrate preparation. Periodic in-progress inspections throughout duration of the project to evaluate membrane and flashing application. Final punch-list inspection at the completion of each phase of the project prior to installation of any surfacing or overburden materials.

Warranty inspection to confirm completion of all punch list items, surfacing, and overburden application. Obtain all principal components of waterproofing system from a single manufacturer. Secondary products that are required shall memperol as recommended and approved in writing by the waterproofing system manufacturer. Upon request of the Architect or Owner, submit Manufacturer’s written approval of secondary components in list form, signed by an authorized agent of the manufacturer.

The following is one example of how a mock-up on a large project might be specified. When deciding on the extent of the mock-up, consider all the major different types of work on the project. Provide a mock-up for evaluation of surface preparation techniques and application workmanship.


Prepare and clean a 3 foot 0. Test each area to verify that substrate preparation meets specified requirements. Tests shall include tensile bond strength and moisture content of substrate. Do not proceed with the work until test results and workmanship are approved by Architect. Maintain mock-up for quality control during the progress of the kfmperol work.

Coordinated with similar paragraphs in Part 3 of this specification. Delete the paragraph s not required. Delete if not required. Verify project compatibility with the membrane manufacture and ensure that all necessary components for the EFVM testing are included in the design. Notify the Architect of and conflicts prior to start of waterproofing work. Field Quality Control Flood Test: Test shall be of a 24 hr. Any incidents of water entry shall be evaluated and all necessary repairs conducted, followed by an additional flood test until all repairs are completed successfully.

Convene a pre-roofing conference approximately two weeks before scheduled commencement of waterproofing system installation and associated work. Require attendance of installers of substrate construction to receive waterproofing, installers of work in and around waterproofing which must precede or follow waterproofing work including mechanical and electrical penetration, equipment openings, subsequent finish work, and the Architect, Owner, and waterproofing system manufacturer’s representative.

Review foreseeable methods and procedures related to waterproofing work, including set up and mobilization areas for stored material and work area.

Tour representative areas of waterproofing substrates, inspect and discuss condition of substrate, penetrations and other preparatory work. Review structural loading limitations of deck and inspect deck for loss of flatness and for required attachment.

Review waterproofing system requirements, Drawings, Specifications and other Contract Documents. Review and finalize schedule related to waterproofing work and verify availability of materials, installer’s personnel, equipment and facilities needed to make progress and avoid delays.

Review weather and forecasted weather conditions and procedures for coping with unfavorable conditions, including kfmperol of kemprol roofing. Record conference including decisions and agreements reached. Furnish a copy of records oemperol each party attending.
