Frequently Asked Questions

Wall ties are critical components in cavity wall construction, designed to enhance the stability and integrity of the structure. These ties are typically made of metal and come in the form of strips or bars. Their primary function is to span the gap between the internal and external walls of a cavity wall system.

In a cavity wall, there are two separate walls—the inner and outer walls—separated by an air gap or cavity. Wall ties are installed across this cavity to connect the two walls securely. This connection helps to:

  1. Maintain Structural Integrity: Wall ties prevent the inner and outer walls from moving independently of each other, which helps to maintain the overall stability of the building.
  2. Enhance Strength: By bridging the gap between the two walls, wall ties distribute loads and stresses evenly across the structure, improving its strength and durability.
  3. Prevent Moisture Penetration: Properly installed wall ties help in reducing the risk of moisture infiltration between the walls, thus protecting the internal walls from dampness and potential damage.
  4. Support Safety: Wall ties are crucial for the safety of the building, as they help prevent issues such as wall bulging or collapse, which can occur if the ties are damaged or improperly installed.

Wall ties come in various types and materials, including stainless steel and galvanized steel, to suit different construction needs and environmental conditions. Regular inspection and maintenance of wall ties are important to ensure their continued effectiveness and the overall safety of the structure.

By understanding the role and importance of wall ties, you can better appreciate their contribution to the longevity and stability of cavity wall constructions.

Wall tie replacement is a specialised service designed to address issues arising from deteriorating wall ties in cavity wall construction.
