    PART 1 - GENERAL

    1.01 DESCRIPTION

    This specification is applicable to extensive green roofs for conventional roofing applications. The waterproofing system utilizes FiberTite thermoplastic membranes and may be loose laid, adhered or mechanically fastened as the project dictates and includes all integral flashing and related accessories as manufactured and supplied by:

    A. Definitions

    1. Extensive Green Roof Systems. Extensive Green Roof Systems are defined as low to no maintenance green

    roof systems that incorporate a waterproofing membrane that is “covered” with soil and vegetation in a

    growing medium that is less than six inches in depth and typically limits access to that required for

    maintenance of the garden and roof-top equipment. Extensive systems incorporate the following items within

    the assembly; Deck/substrate, insulation, leveling mat, waterproofing membrane, flashing membrane, sealant

    and adhesives, metal flashing, protection layer, drainage layer, filter fabric, growing medium, and

    plants/vegetation.

    * The growing medium and selection of appropriate vegetation is critical to the system’s performance and must

    be properly engineered for each application. Seaman Corporation does not provide engineering for the

    garden/vegetated system and strongly recommends the use of a qualified landscape architect/engineer.

    B. Scope

    Furnish and install FiberTite membrane waterproofing system for application within a roof top garden, including insulation, cover-board, integral flashing protection layer, drainage medium and engineered garden system components as may be required.

The work included but is not necessarily limited to the following:

    1. Substrate Preparation

    2. Insulation

    3. Waterproofing membrane

    4. Membrane Flashing

    5. Metal Flashing

    6. Sealants and Adhesives

    7. Protection Layer

    8. Drainage Layer

    9. Installation of Engineered Soil or Pre-packaged Garden System

    C. Design Considerations

    1. This specification is to be applied, without variation, to only those building roofs having deck structures capable of

    supporting the loads associated with this type of installation.

    2. The building owner shall secure a Statement of Sound Roof Structure, and submit to FiberTite Technical

    Customer Services (FTCS), indicating that the structure will accommodate the live and/or dead loads. 3. All applications require review and acceptance FTCS before any modification of this specification is valid. 4. FiberTite Notification of Award / Warranty Request Form (FTR-WRF) must be completed, signed by appropriate

    parties, submitted to, and approved by FTCS prior to any consideration for warranty.

    5. Green Roof areas subject to maintenance traffic should be designed with proper access “paths”.

    6. Excess “ponding” and/or water retention due to improper drainage design.

    7. Conditions within an existing structure or roof, which would prohibit a successful application.
