Wall Tie

What is Wall Tie?

Metal connectors that secure masonry veneer to structural backing walls, providing lateral support and load transfer.

Description

Wall Tie is metal connectors that secure masonry veneer to structural backing walls, providing lateral support and load transfer through corrosion-resistant hardware that creates structural connections between exterior masonry and interior framing systems while allowing for differential movement and thermal expansion. This essential masonry component consists of galvanized steel, stainless steel, or other corrosion-resistant metal fabricated into various configurations that anchor brick, stone, or block veneer to wood or steel framing, concrete, or masonry backup walls. Wall ties are critical in masonry construction where they provide structural stability, resist wind and seismic forces, transfer lateral loads, and maintain veneer alignment, making them indispensable for brick veneer construction, stone cladding systems, and any masonry application where secure attachment to structural backing is necessary for building safety and long-term performance.

Wall ties are utilized in various masonry applications and construction systems including brick veneer construction where they connect brick facades to wood or steel frame backing, stone veneer installations where they secure natural or manufactured stone to structural walls, concrete masonry unit (CMU) construction where they tie wythe walls together or connect to backup systems, cavity wall construction where they span insulated cavities while maintaining structural connection, restoration projects where they replace deteriorated ties in existing masonry, and specialty applications including seismic retrofits, historic preservation, and high-wind construction where enhanced tie systems provide additional structural capacity. Each application requires appropriate tie selection, spacing, and installation methods based on structural requirements and building codes.

The types and configurations of wall ties include corrugated ties that use bent metal strips for basic veneer attachment, adjustable ties that accommodate varying cavity widths and construction tolerances, rigid ties that provide fixed connections for specific applications, flexible ties that allow differential movement between veneer and backing, seismic ties that provide enhanced capacity for earthquake resistance, and specialty ties including thermal break ties, long ties for thick insulation, and custom configurations for unique construction requirements. Tie type selection depends on structural loads, construction methods, and performance requirements.

FAQs

  • What is a wall tie?

    A wall tie is a metal connector that secures masonry veneer to structural backing walls, providing lateral support and load transfer.

  • What materials are wall ties made from?

    Wall ties are typically made from galvanized steel, stainless steel, or other corrosion-resistant metals.

  • How are wall ties spaced?

    Wall tie spacing is specified by building codes, typically ranging from 16 to 32 inches on center depending on application and loads.

  • What types of wall ties are available?

    Types include corrugated ties, adjustable ties, rigid ties, flexible ties, seismic ties, and specialty configurations.

  • Why do wall ties fail?

    Common causes include corrosion, inadequate spacing, improper installation, excessive loads, and moisture infiltration.

  • How are wall ties installed?

    Installation involves fastening to backing walls, proper embedment in mortar joints, and ensuring correct spacing and alignment.

  • Can wall ties be repaired or replaced?

    Yes, failed ties can often be replaced using retrofit tie systems, though this requires careful structural evaluation and proper installation.

Fun Fact

Fun Fact: Wall ties were first used in ancient Roman construction, and modern stainless steel ties can last over 100 years while supporting loads exceeding 1,000 pounds per tie in seismic applications.
