Guide to Retrofitting Non-Structural Walls with Wall Mesh: Execution Principles

Why is Protecting Non-Structural Walls Against Earthquakes Vital?

In recent years, seismic design codes have paid special attention to non-structural elements. Although infill walls and partitions are not the main load-bearing parts of a building, their destruction during an earthquake can cause irreparable loss of life and financial damage. The collapse of these walls is considered one of the main causes of human casualties in moderate and severe earthquakes. For this reason, structural engineers are looking for modern, fast, and economical solutions to reinforce these components.

One of the most efficient methods that has replaced traditional methods such as heavy angle bracing today is the technique of retrofitting non-structural walls with wall mesh. By creating a continuous network on the wall surface, this technology optimizes stress distribution and prevents sudden wall collapse. To better understand the economic and execution fundamentals of this system, we suggest taking a look at wall mesh prices and the non-structural wall retrofitting guide to become more familiar with cost details and its benefits.

The Key Role of Wall Mesh in Structural Stability

The wall mesh system functions similarly to reinforced concrete; with the difference that here, fiberglass fibers are used along with mineral plasters. This combination gives the wall extraordinary flexibility, allowing it to withstand the lateral deformations of the structure without deep cracking or collapse. Engineering research shows that using composite systems in seismic retrofitting performs much better than traditional methods retrofitting non-structural walls with wall mesh. The Modern Wall Mesh Department has taken a big step toward upgrading the safety of the country's structures by offering standard products such as E-Glass, C-Glass, and Zr-Glass fiberglass mesh.

Main Components Comprising the Wall Mesh System

For the proper execution of the wall mesh system, precise knowledge of the materials and consumables used is of high importance. This system consists of several coordinated components, each performing a specific task in load-bearing and element continuity. The quality of materials directly affects the final durability and efficiency of the system.

The main components include the following:

• Fiberglass Mesh: A mesh network made of glass fibers with high tensile strength.
• Plaster (Render): Special gypsum- or cement-based mortar for covering the mesh.
• Connection Angles or Channels: To restrain wall edges to structural members.
• Epoxy Adhesives or Anchors: For connecting restraining elements to beams and columns.

Types of Fiberglass Mesh from the Modern Wall Mesh Department

The choice of mesh type depends on environmental conditions and design regulations. E-Glass mesh for general construction uses, C-Glass mesh for chemical materials and special environments, and Zr-Glass mesh due to its excellent resistance to alkaline environments (such as cement plasters) are widely used. Using high-quality gypsum-based or cement-based plaster also creates proper adhesion between the mesh and the wall surface.
