How to Install Wall Ties: A Comprehensive Guide

Wall ties are essential components in cavity wall construction, providing structural integrity and stability. They connect the inner and outer leaves of the wall, preventing separation and potential collapse. Proper installation of wall ties is crucial to ensure the building's structural integrity and prevent issues like damp penetration and cracking.

Types of Wall Ties

Selecting the correct type of wall tie is crucial, as different types are designed for specific applications and wall constructions. Here are some common types of wall ties:

1. Stainless Steel Wall Ties

Stainless steel wall ties are renowned for their corrosion resistance and strength, making them suitable for various applications. They are available in different types to suit specific wall tie requirements, including:

2. Basalt Wall Ties

Basalt wall ties offer exceptional strength, durability, and thermal efficiency. They are ideal for use in projects where thermal performance is a priority, such as those aiming to meet Passivhaus standards. Explore our range of basalt wall ties here.

Wall Tie Installation Guide

  1. Determine the Correct Tie Length: Refer to the manufacturer's guidelines or building regulations (like PD 6697) to determine the correct tie length for your cavity width. Ensure adequate embedment in both leaves of the wall, typically a minimum of 50mm.
  2. Spacing and Positioning: Space wall ties evenly, generally at 2.5 ties per square metre (900mm horizontal x 450mm vertical centres). Adjust spacing based on the tie length and cavity width. Consult PD 6697 for detailed guidance.
  3. Installation: Press ties firmly into fresh mortar bed joints, ensuring they are fully embedded and surrounded by mortar. Install with a slight fall to the outer leaf to prevent moisture tracking.
  4. Drip Detail: Position the drip part of the tie downwards to direct moisture towards the cavity and prevent it from reaching the inner leaf.
  5. Avoid Bending: Do not bend wire ties after installation, as this can compromise their performance and structural integrity.

Safety Considerations

  • Protruding wall ties can be hazardous. Build both wall leaves simultaneously to minimise risk.
  • Wear appropriate safety gear, including gloves and eye protection.

Building Regulations and Standards

Always comply with relevant building regulations and standards. PD 6697 offers comprehensive guidance on wall tie design, selection, and installation in the UK.
