Section 1: Why Balcony Waterproofing Specs Fail

The document details common failures in balcony waterproofing specifications, such as generic membrane specs, missing detail references, and inadequate scope assignments, which lead to leaks and warranty disputes. It then presents the "FM ELEVATION System" as a complete solution, specifying products, controlling sequencing, assigning transition responsibilities, and requiring documentation for a comprehensive 10-year warranty.

Section 2: MasterSpec Division 07 Language for FM ELEVATION

MasterSpec language is provided for balcony waterproofing using the FM ELEVATION system, detailing specific products such as SP1 Primer, S60 Sheet Membrane, and DM2 Drainage Mat from Formulated Materials. It outlines installation procedures, submittal requirements, and a 10-year system warranty contingent on an FM-approved applicator, a specific product assembly, and a successful 24-hour flood test.

Section 3: TTP Details and Drawing Set Integration

FM's Tested Transition Profiles (TTP) are prescriptive installation details for balcony waterproofing transitions, with a reference table outlining specific conditions and their applications. The document details how to integrate these TTPs into drawing sets and specifications, including requirements for flood testing and common mistakes to avoid in documentation.

Section 4: Railing Embed Waterproofing

Railing embed waterproofing failures, primarily caused by misaligned structural and waterproofing scopes, are addressed through the TTP-6 Pocket Method. This method details forming and waterproofing a pocket for railing posts *before* their installation, mandating precise coordination between structural and waterproofing contractors to prevent membrane penetrations and ensure long-term integrity.

Section 5: FM 10-Year Warranty Requirements

This document outlines the requirements for an FM 10-Year System Warranty, detailing what the warranty covers, specific conditions that void it, and a comprehensive submittal checklist for its application. It also provides precise specification language for project documents, ensuring proper installation, product use, and documentation are met for warranty eligibility and timely submission.

Section 6: Pre-Bid Coordination Checklist for FM Waterproofing

This document provides a pre-bid coordination checklist for FM waterproofing, detailing specific requirements for bid packages, including specifications, warranty, and drawing notes, and assigning responsibilities for various waterproofing components to different divisions. It also outlines a pre-installation meeting agenda to confirm applicator qualifications, review technical details, coordinate with other trades, establish flood testing procedures, and plan the sequencing of work.
