Top 3 Key Areas to Consider in a Restoration Project

Restoring aging structures is more than just repairing what is broken, it is about preserving history while ensuring durability for the future. The biggest challenge? Finding materials that seamlessly integrate with existing structures, meet industry compliance standards, and provide lasting protection without compromising the building’s original character.

As the leading supplier of restoration solutions in New Zealand, Mapei provides lime-based mortars, structural consolidation systems, and high-performance waterproofing solutions that offer a faster, proven, and cost-effective way to restore historic buildings while reducing project risks. With Italian heritage and decades of expertise, Mapei has restored icons like The Colosseum and The Palace of Versailles. Backed by world-class R&D, we deliver trusted solutions to restore history with confidence. Mapei’s solutions not only maintain authenticity but also improve efficiency, reduce long-term maintenance costs, and enhance structural resilience for making them the preferred choice for heritage restoration projects.

To achieve successful heritage restoration, three key factors must be carefully considered:

1. Preserving Aesthetic Integrity in Heritage Restorations

New Zealand’s historic buildings are defined by their unique architectural character, making aesthetic preservation a top priority in any restoration project. Mapei’s Mape-Antique range, formulated with lime and Eco-Pozzolan, ensures that restoration materials blend seamlessly with the original structure, maintaining the historic look and feel while improving durability. Whether restoring the stonework of Auckland’s St. Patrick’s Cathedral or the timber and brick integrity of Wellington’s Old Government Buildings, Mapei’s breathable, flexible mortars and finishing coats help achieve authentic restoration without compromising structural performance. With a range of textures, colours, and application techniques, these solutions enable architects and conservationists to recreate historic finishes while protecting against weathering and deterioration.

2. Enhancing Seismic Resilience in Earthquake-Prone Regions

Seismic resilience is a critical factor in restoring heritage buildings in earthquake-prone regions especially in Christchurch. Mapei’s reinforcement and consolidation solutions, including volumetrically stable injection slurries and lime-based skimming mortars, help strengthen aged masonry while preserving its historical integrity. In the Christchurch Cathedral Rebuild, Mapei’s advanced mortars and consolidation systems were used to repair and reinforce stone and plaster elements, helping to ensure the structure’s ability to withstand future seismic events. By integrating traditional materials with modern engineering advancements, Mapei provides long-term structural stability while safeguarding the architectural heritage of New Zealand’s most treasured landmarks.

3. Managing Moisture for Long-Term Protection

One of the key challenges in heritage restoration is moisture management. Mapei-Antique Rinzaffo and Mapei-Antique MC, part of Mapei’s dehumidifying system, effectively combat rising damp and salt efflorescence, which are common in older masonry structures. These lime-based renders allow the building to breathe while preventing future deterioration, making them ideal for seaside and high-humidity environments. For projects such as the Chapel of Faith, Mapei’s breathable renders and finishing coats were applied to enhance durability while maintaining the structure’s original appearance.

Mapei’s solutions are designed to enhance durability, improve building performance, and minimise long-term maintenance needs. Whether it is for structural reinforcement, surface consolidation, or waterproofing historic buildings, Mapei provides tailored, scientifically tested solutions that allow for seamless integration with existing materials while ensuring long-lasting results.
