Our Work

With over 25 years of experience, G&W Science and Engineering has become a leader in the precise analysis of building materials with huge partners.

The Khayer bek Mosque, a stunning example of Mamluk architecture, was restored to its former glory through a detailed analysis and conservation process led by G&W Science & Engineering. Our work focused on preserving both the structural and artistic elements of this historic site:

• Building Materials Analysis: We performed a thorough microstructural, chemical, and mineralogical analysis of the mosque's stone, mortar, and decorative materials. This analysis was crucial in guiding the restoration efforts, ensuring that all materials used were historically accurate and structurally sound.

• Decoration Conservation: The intricate tilework and plaster decorations, key features of the Khayrbak Mosque, were carefully restored. Our team employed advanced techniques to clean, stabilize, and preserve these elements, maintaining their original beauty and craftsmanship.

• Color Restoration: We conducted detailed color analysis to identify and replicate the mosque's original color schemes. This process ensured that the restored mosque retained its historical authenticity, with colors that reflect its original Mamluk splendor.

Ayyubid wall (Salah El-Din Citadel)

The Ayyubid Wall, an essential part of Cairo's historical fortifications, required extensive restoration to preserve its structural integrity and historical significance. G&W Science & Engineering led a detailed investigation and restoration process, addressing the following key areas:

• Structural Analysis: Our team conducted a comprehensive microstructural and mineralogical analysis of the wall's stone materials. By examining the composition and condition of the stones, we developed a restoration plan that reinforced the wall’s structure while maintaining its historical authenticity.

• Material Compatibility: The restoration involved careful selection of compatible materials for repair and reinforcement. We analyzed the original gypsum and mortar used in the wall's construction, ensuring that new materials would integrate seamlessly with the existing structure.

• Surface Treatment: To protect the wall from environmental degradation, we applied advanced chemical treatments that preserved the stone’s surface without altering its historical appearance.

Mosque of (Amir al-Maridani)

The Mosque of Amir al-Maridani, a historic gem located in Cairo, underwent a comprehensive restoration to preserve its architectural and artistic heritage. Our team at G&W Science & Engineering conducted detailed analyses and conservation efforts across multiple aspects of the mosque:

• Building Material Analysis: We performed in-depth microstructural, chemical, and mineralogical analyses on the materials used in the mosque's construction. This included the assessment of gypsum and mortar to ensure their long-term stability and compatibility with restoration materials.

• Decoration Restoration: The intricate decorations, including the tilework and plaster ornamentation, were meticulously analyzed and restored. Our experts used advanced techniques to preserve the original colors and patterns, ensuring the authenticity of the decorative elements.

• Color Preservation: The mosque’s historical color schemes were carefully studied using spectroscopic methods. We identified and recreated the original pigments to restore the mosque’s vibrant hues while maintaining the integrity of the original materials.
