What Is the FM S60 Balcony Waterproofing Assembly
The FM S60 system is a fully bonded sheet membrane assembly for above-grade concrete balconies, detailing its core components like primer, membrane, drainage mat, and protection board, along with their functions and common failure points. The guide targets contractors, applicators, and owners, stressing the importance of following the specified installation sequence to ensure warranty eligibility and avoid expensive reworks due to interdependencies between layers.
Check 1: Substrate Readiness Before Primer
Substrate readiness before primer application requires a comprehensive inspection covering concrete cure, moisture levels, surface condition, and proper slope and drainage. This checklist serves as a mandatory hold point, ensuring all specified conditions are met and signed off by an inspector to prevent issues before proceeding with primer.
Check 2: SP1 Primer Application and Coverage
This document details the critical steps and conditions for applying SP1 primer, including pre-application requirements, proper application techniques, and flash-off/cure criteria. It functions as a checklist and documentation log to ensure correct primer application and confirm readiness for subsequent S60 membrane installation.
Check 3: S60 Membrane Seams and Lap Inspection
This document provides a detailed inspection checklist for S60 membrane seams and laps, covering specific criteria for roll sequencing, seam laps, membrane condition, and drain integration. It establishes a critical hold point requiring all seams to pass inspection and be signed off by an inspector before the drainage mat can be placed.
Check 4: Transitions, Penetrations, and Wall Terminations
This document provides a detailed inspection checklist for critical waterproofing elements in construction, specifically focusing on transitions, penetrations, and wall terminations. It outlines specific requirements for membrane laps, adhesion, flashing, and sealing around various building components like walls, pipes, coves, and through-the-parapet pockets, culminating in an inspector sign-off before a flood test.
Check 5: Scupper Sequencing and Membrane Integration
This document provides a comprehensive inspection checklist for scupper sequencing and membrane integration, detailing critical steps from scupper pre-set conditions to membrane application and throat/outlet clearance. It serves as a quality control hold point, requiring inspector sign-off on all checks before proceeding to a flood test.
Check 6: Membrane Cure Verification Hold Point
This document outlines the mandatory "Check 6: Membrane Cure Verification Hold Point," which must be completed and logged before proceeding to flood testing or drainage mat installation. It details specific requirements for membrane cure time, ambient conditions during cure, and physical verification of the membrane's cured state, with a log provided for recording all necessary information and approval.
Check 7: Drainage Mat Orientation and Edge Overlaps
This document provides a detailed inspection checklist for drainage mat installation, covering critical aspects such as correct orientation, complete coverage, and proper termination at edges, drains, and scuppers. It specifies requirements for seam overlaps, clean cuts, and the accessibility of components, culminating in an inspector sign-off before further construction.
Check 8: 24-Hour Flood Test Protocol
This document outlines a mandatory 24-hour flood test protocol for verifying membrane integrity before drainage mat installation, detailing specific steps for setup, filling, and the hold period. It provides clear pass/fail criteria, procedures for addressing failures, and a log for documenting water levels, times, and inspector sign-off, requiring photographic evidence.
Check 9: Protection Board Coverage Before Topping
This document details a critical pre-topping inspection for protection board coverage, outlining specific criteria for proper installation before concrete or tile is applied. It covers requirements for board coverage, condition, and clearances around drains, scuppers, walls, and penetrations, concluding with a mandatory project manager approval and inspector sign-off.
Check 10: Final Sign-Off and Warranty Documentation
This document details the comprehensive set of documentation required for a successful FM 10-Year Warranty submittal, including various sign-offs, logs, batch numbers, and project information. It also outlines the final quality control walk process and the steps for submitting the warranty package to Formulated Materials, emphasizing the need for a complete package and confirmation.
