A New Approach to Dry Stone Cladding

This article illustrates a new approach to the design and installation process to dry stone cladding to provide an ETA-approved engineered system.

The last twenty years have seen the rise of two very common façade types – glass and stone. When compared, the latter is simpler to design but the erection is time-consuming and maintenance a true headache. Additionally, the system design of a stone-clad building envelope using the current system of anchors and clamps can be improved, particularly relating to aesthetics, design flexibility, lifecycle maintenance, as well as using an engineered and third-party approved system.

Driven by a need to provide effective and innovative solutions for construction professionals, Hilti introduces a novel approach to cladding with stone panels using an undercut anchor, which is as simple as hanging and dismounting photo frame on wall.

The design and installation processes are straightforward and provide architects and façade designers with an ETA-approved and engineered system.

Within these steps, the anchor and its proper installation into the stone panel is the paramount component but what type of anchor can safely transmit the stone panel’s load to the frame and conversely not damage the panel itself? Is it approved by an independent third-party? Will it suit or interfere with the overall aesthetics? Is it safe at heights? Can it be replaced if damaged?

The new Hilti HSU-R stone undercut anchor addresses these concerns:
