Restoration and
Existing Construction

Historic and existing masonry buildings have common issues that architects, engineers, conservators, contractors, and owners are often challenged with evaluating and addressing. Historic generally refers to buildings 50 years of age or greater with significance architecturally or culturally.

Thoughtfully and appropriately designed repair and restoration projects can preserve the integrity of the masonry building and continue its life for future decades. From a sustainability perspective, the greenest building is the one that already exists.

With greater knowledge of masonry material properties, wall systems, condition assessments, and best practices for repair and restoration strategies, design and construction professionals can successfully develop and implement appropriate solutions for their culturally significant and existing projects.
