Following on from our previous update covering the history of the building and our ongoing basement waterproofing works, we are pleased to share further insight into the structural repair works undertaken by Protectahome at the historic Bristol Guildhall.

In addition to our waterproofing responsibilities, the developer engaged Protectahome to assist with a number of complex and highly sensitive structural repairs—drawing on our specialist skill set, experience with historic buildings, and practical, solutions-led approach.

Cintec Anchoring to the Broad Street Tower

One of the most technically demanding elements of the project involved the installation of Cintec anchoring systems to the Gothic-style Broad Street tower. Working to the structural engineer’s design, our team installed Cintec anchors ranging from 2.5 metres to 6 metres in length, installed on an inclined plane—a challenging sequence of works requiring absolute accuracy.

This type of Cintec Anchoring in Bristol, particularly to a historic façade, demands extensive experience and a deep understanding of heritage structures. Our specialist operatives successfully completed the installation using proven techniques developed over many years of working on listed and conservation-led projects.

Once installed, the façade cores were carefully re-bedded, delivering a fully concealed structural repair that reinforces the tower while preserving its original architectural appearance.

Structural Integration at Basement Level

At basement level, further structural repairs were required to link the new concrete frame to the existing South East Courtyard elevation wall. This involved installing a series of structural brackets designed to seamlessly connect the historic masonry with the new structural elements—effectively marrying old and new construction.

Again, all works were carried out strictly in accordance with the structural engineer’s design and specifications. The process required the procurement of bespoke materials and the fabrication of custom stainless steel brackets to suit the unique conditions of the building.

Bespoke Materials & Specialist Supply Chain

Protectahome’s long-established specialist supply chain played a key role in the successful delivery of these works. All components were manufactured and supplied to exacting standards, including:

• Stainless steel brackets
• PTFE pads and washers
• Elongated fixing holes to allow for future settlement of the new structure

These details are critical in heritage-led structural repairs, ensuring long-term performance without imposing unnecessary stress on the retained façade.

Specialist Structural Repairs for Historic Buildings in Bristol

We are increasingly seeing projects across Bristol and the wider UK where historic façades are retained while new structures are constructed within the original footprint. This approach creates significant opportunities—and challenges—for specialist anchoring systems, bespoke fixings, and advanced repair techniques.

Protectahome continues to support these schemes by delivering carefully designed and expertly installed structural repair solutions, including Cintec anchoring, tailored to the unique demands of each historic building.
