Basalt Mesh Repairs — Fyfe Europe Projects
There are many historic and other masonry structures that require strengthening while being compatible with existing materials and maintaining their textures and colors. Fyfe Europe S.A. has developed the Tyfo® RM System. Comprised of a specialized EP (open weaved) fabric that is installed in a mortar matrix compatible with the substrate and the materials of the structure. The standard EP fabrics for the System are the Tyfo® EP-B Basalt fabric and the Tyfo® EP-C Carbon fabric. Standard Tyfo® EP Fabrics are bidirectional (0°/90°) open weaved (1″x1″) with a special high temperature resistive coating for fabric and joints stability. Click here for a full report.
PROJECT ONE: 19th century historical building Masonry wall strengthening
Built in 1884, this building was designed by French-Ottoman architect Alexander Vallaury, and is a unique structure. Recently, the building was lent to a private firm for duration of 25 years and the firm decided to strengthen some of the masonry walls due to their insufficient shear capacity. Since the building is a historical structure of 1st degree, classical strengthening techniques, e.g. adding reinforced concrete shear walls, could not be used during the rehabilitation.
The solution — Tyfo® RM (Reinforced Mortar) Basalt System and masonry anchors. Basalt fabric reinforced hydraulic mortar system was applied on the wall to be strengthened. Masonry anchors were installed. Galvanized steel plates were fastened onto the wall using nuts so that a uniform pressure was applied across the Tyfo® RM Basalt System to delay debonding during a possible seismic event. Finally, the wall was covered with “Horasan” mortar (pink colored, weak mortar with lime mortar+brick pieces). Link to full story.
