One of the key advantages of using flexible wall ties is their ability to accommodate differential movement between the inner and outer leaves. Buildings naturally expand and contract due to temperature variations; thus, wall ties must be capable of tolerating this movement without compromising the wall's stability. Flexible wall ties are typically made from materials such as stainless steel or other corrosion-resistant materials, thus ensuring longevity and reliability over time. Their inherent flexibility allows them to absorb and redistribute stress, minimizing the risk of cracks and structural failure.

Moreover, tie-in brickwork is crucial in resisting lateral forces, such as those caused by wind or seismic activity. As buildings age, settling and shifting can create vulnerabilities. By employing tie-in techniques, the movement of new brickwork is aligned with the existing structure, enhancing its ability to withstand these forces. This is particularly vital in seismically active regions, where buildings are subjected to significant stress and must be designed to endure unpredictable conditions.
