The Science Behind Bonding, Decking Uplift Resistance & Lateral Loads - Advanced Engineering.

INTRODUCTION

This article examines the physics behind adhesive performance, load transfer, and structural reliability in rooftop decking applications.

SECTION 1 — UPLIFT RESISTANCE MECHANICS

Adhesive tensile capacity counters vertical suction forces. Key factors:

• Bond area 

• Adhesive type 

• Membrane strength 

• Cure time and conditions 

SECTION 2 — LATERAL LOAD PATHS

Balustrades generate high lateral loads. These forces are resisted through:

• Adhesive shear strength 

• Friction coefficient 

• Perimeter contact 

SECTION 3 — FAILURE MODES

1. Peel Failure 

2. Shear Failure 

3. Membrane Delamination 

BalcoDeck® avoids these through:

• Larger adhesive footprints 

• Redundant anchorage methods 

• Conservative load assumptions 

SECTION 4 — MEMBRANE-TO-SUBSTRATE BONDING

A strong adhesive bond is only as strong as the membrane-to-roof bond. Verification is essential.

CONCLUSION

Adhesive engineering is a science — and BalcoDeck® applies it thoroughly.
