BalcoDeck® Non Penetrative Anchorage Methods
INTRODUCTION
BalcoDeck® uses five anchorage techniques that may be applied individually or combined based on project requirements. This article explains the engineering logic, performance benefits, and installation considerations of each.
SECTION 1 — SURFACE ADHESIVE BONDING
Polyurethane adhesives such as Sikaflex®-11 FC+ provide:
• Tensile resistance for uplift
• Shear resistance for lateral loads
• Vibration damping
• Membrane-safe connection
Engineering Notes:
• Adhesive strength far exceeds typical wind loads
• Peel resistance depends on membrane bonding quality
• Wider pedestal bases distribute loads more effectively
SECTION 2 — BALLASTING
Ballasting adds downward force and increases friction.
Typical values:
• 10–12 kg/m² supplemental mass
• Even distribution prevents membrane overloading
Advantages:
• Ideal for EPDM/PVC/TPO where adhesives are unsuitable
• Enhances global system stability
SECTION 3 — FRICTIONAL RESISTANCE
Standard membranes provide μ ≈ 0.3.
Rubber pads increase this to μ ≈ 0.6.
Higher friction reduces shear demand on adhesives.
SECTION 4 — PERIMETER ENGAGEMENT
Close interface (<10 mm) with parapets creates:
• Natural bracing
• Confined movement
• Improved lateral stability
SECTION 5 — MECHANICAL FIXING INTO VERTICAL WALLS
Used only when permitted, offering:
• Additional lateral anchorage
• Strong restraint at exposed edges
Only stainless-steel fixings are used for longevity and safety.
CONCLUSION
BalcoDeck® anchorage is a multi-layered system engineered for redundancy and robustness.
