FAQs
Are these ties suitable for high-rise buildings?
No, these are Type 4 ties designated for light-duty housing applications up to a maximum height of 10 meters.
What is the primary function of the double drip design?
The double drip design is a safety feature that causes moisture traveling along the tie to fall off before reaching the inner leaf, preventing dampness.
Do these ties meet British Standards?
Yes, they are tested and certified to comply with BS EN 845-1 standards.
Can I use these for a 50mm cavity?
No, these 225mm ties are specifically designed for cavity widths between 76mm and 100mm.
Are these made of rust-proof material?
They are constructed from high-quality stainless steel, which provides excellent resistance to the corrosive environment found within wall cavities.
Troubleshooting
Difficulty inserting ties into hard mortar
Ensure that the mortar bed is sufficiently fresh and plastic before attempting to place the tie to prevent displacement of the units.
Concerns regarding moisture dampness on internal walls
Inspect the cavity to ensure no excess mortar droppings have landed on the ties, as these can bridge the moisture gap.

Setup, Compatibility & Care
For optimal performance, these ties must be installed in accordance with local building regulations regarding density and spacing. Ensure the ties are kept clean and free from excess mortar during the construction process, as mortar droppings can create bridges that allow water to bypass the drip feature. These ties are compatible with standard brick and block dimensions commonly found in the UK residential market. No specialized maintenance is required post-installation, as the high-grade stainless steel is designed for permanent, maintenance-free service within the wall structure.
