Aqueduct Sculpture Conservation Maintenance

2 Brindleyplace, Birmingham, England

Project Overview

The Aqueduct Sculpture Conservation Maintenance project at 2 Brindleyplace, Birmingham, involved the careful cleaning, protection and preservation of the renowned bronze sculpture Aqueduct by Miles Davies.

Exposure to the environment had resulted in the accumulation of atmospheric pollutants, biological growth and surface contamination across the sculpture. Rather than restoring or refinishing the artwork, the objective was to preserve its historic bronze surface and existing patina through a carefully controlled cleaning and waxing programme. All works were undertaken in accordance with recognised heritage conservation principles, ensuring minimal intervention while enhancing the sculpture’s appearance and long-term protection.

Craftsmanship and Materials

Prior to treatment, the sculpture underwent a detailed visual inspection to assess the condition of the bronze surface, patina stability and the presence of environmental contaminants.

Surface deposits, biological growth and atmospheric pollutants were carefully removed using conservation-approved, non-abrasive methods. Cleaning was undertaken using distilled water combined with a mild non-ionic detergent, applied with microfibre cloths, lint-free cotton cloths and soft natural-bristle brushes to minimise any risk of abrasion.

Where localised staining and more persistent contamination were encountered, a controlled solution of approximately 10% white vinegar in distilled water was used to reduce deposits before being thoroughly rinsed and dried.
Upon completion of the cleaning process, two coats of conservation-grade Renaissance Wax were applied to the bronze surface. Each coat was allowed to cure before being carefully hand-buffed to provide a consistent finish and durable protective barrier against future environmental exposure.

On-Site Challenges & Considerations

One of the most important aspects of the project was preserving the sculpture’s existing patina. The historic surface forms both an important visual characteristic and a naturally protective corrosion layer that contributes to the long-term stability of the bronze.

As a result, all cleaning methods were carefully selected to avoid removing stable patinated surfaces or original historic material. The conservation programme followed a minimal intervention approach, balancing visual improvement with responsible preservation.

Working within a public environment also required careful planning to ensure the sculpture remained protected throughout the maintenance works while minimising disruption to visitors and the surrounding area.

Final Result & Special Notes

The conservation maintenance programme successfully cleaned and protected the Aqueduct sculpture while preserving its historic patina and character. A protective Renaissance Wax coating was applied to help reduce the effects of weathering, pollutants and moisture, supporting the long-term preservation of this important public artwork.
