This week, our team participated in a CPD session presented by Amy from Leviat. The session focused on “Considered Façade Solutions for Complex Applications,” a crucial topic for those of us working with bespoke façade support and restraint systems. This is especially relevant in the context of slab edge complexities.

Their innovative solutions focus on connecting, fixing, lifting, and anchoring technology, ensuring that structures are stronger, safer, and more efficient.
CONSIDERED FAÇADE SOLUTIONS
Understanding the Complexity of Façade Construction

The presentation began with an overview of the intricate nature of façade construction. It was highlighted that in modern architectural designs, aesthetics, functionality, and sustainability are all essential considerations. Understanding these complexities is critical for architects, engineers, and building professionals. This understanding allows them to maintain control over the design process while staying within budget constraints.

Moreover, the session also underscored how rapidly evolving building regulations have made slab edge zones increasingly congested. This complexity arises from the integration of multiple elements, such as fire barriers, balcony connectors, and masonry supports. All of these components must work together seamlessly, which can be quite challenging.

Key Insights from the Session
Slab Edge Complexity and Interactions:

The session began by discussing the challenges of detailing slab edge products. It was shown how interactions between these elements can significantly impact the design of the masonry support system. Therefore, recognising these complexities early in the design process is crucial. This approach helps avoid costly revisions and ensures structural integrity.

Wall Ties and Masonry Support:

Next, the importance of the first wall tie in relation to the masonry support level was underscored. It was explained that failing to meet the requirements for wall ties can lead to serious consequences, potentially compromising the entire support system.

Damp Proof Coursing and Cavity Trays:

The session highlighted the need for proper detailing of dampproof coursing and cavity trays around the masonry support system. This detailing is essential to prevent water ingress and protect the structure from moisture damage.

Managing Protruding Secondary Structures:

Additionally, the unique challenges posed by secondary structures, such as steel framing systems, were addressed. The presentation covered best practices for managing these protrusions. These strategies help minimise disruption to the façade’s integrity.

Designing for Large Cavities and Pier Applications:

When designing for large cavities and masonry pier applications, careful consideration is required. During the session, it was explored how increasing cavity sizes can significantly affect overall support requirements. Furthermore, techniques for managing these complexities effectively were also shared, offering practical solutions for optimising design.

Fire Barriers and Their Role:

Similarly, fire barriers were highlighted as critical for ensuring the safety and integrity of a building. The session discussed how these barriers integrate with the masonry support system.

Balcony Connectors and Seamless Detailing:

Another key point was Leviat’s unique strength in providing both masonry support and balcony connectors. This dual provision enables seamless detailing, which reduces coordination issues and simplifies the overall design process.

Impact of Post-Tension Slabs:

Additionally, post-tension slabs, often used to reduce slab thickness and enhance performance, can significantly impact masonry support design. Strategies were presented to effectively address these challenges.

Plenum Vents and EPDM Installation:

Finally, the session concluded with a discussion on the coordination of plenum vents around masonry support systems and the critical importance of correct EPDM membrane installation. Poor installation practices can compromise support systems and lead to water ingress.

CONSIDERED FAÇADE SOLUTIONS
The CPD session provided valuable insights into the complexities of designing façade support systems for modern buildings. By considering all components required in the slab edge area—such as fire barriers, balcony connectors, and masonry supports—our team is now better equipped to handle these challenges.

Leviat’s expertise in façade solutions ensures that we can confidently specify systems that meet both aesthetic and functional demands without compromising safety or compliance. We look forward to applying these insights to our upcoming projects.
