—

In the modern construction industry, increasing the safety of structures against lateral forces such as earthquakes and wind has become one of the most important concerns for engineers and project executors. Although non-structural walls do not bear loads, if executed incorrectly, they can cause significant life and financial losses. One of the innovative and effective solutions for restraining and reinforcing these walls is the use of Wall Mesh, also known as Fiberglass Wall Post. This modern technology, designed based on fiberglass mesh, is considered a lightweight, economical, and efficient alternative to traditional metal wall posts.

What is Wall Mesh?

Wall Mesh is a type of reinforcement and restraint system for non-structural walls, executed using high-resistance fiberglass mesh and special mortar or plaster. This system, by creating a cohesive network on the wall surface, evenly distributes incoming forces and prevents stress concentration, cracking, and wall collapse.

In fact, Wall Mesh performs the same function as metal wall posts, but without the disadvantages such as heavy weight, corrosion, difficult installation, and high costs.

What is Fiberglass Mesh?

Fiberglass mesh is a woven network of high-strength glass fibers, usually coated with alkali-resistant (AR) materials to ensure high durability against cement mortar and environmental conditions. These meshes have features such as:

• High tensile strength

• Very low weight

• Appropriate flexibility

• Resistance to moisture, corrosion, and chemicals

making them an ideal option for reinforcing building walls.

What is a Fiberglass Wall Post and How Does It Differ from a Metal Wall Post?

Fiberglass wall post is essentially the Wall Mesh system, which uses fiberglass mesh and reinforcing mortar instead of metal profiles. The main differences between these two systems are:

1. Weight

Fiberglass wall posts are much lighter than metal wall posts and do not impose additional dead load on the structure.

2. Corrosion Resistance

Unlike metal, fiberglass does not rust or corrode and has a longer service life.

3. Speed and Ease of Installation

Wall Mesh installation does not require welding, cutting, or complex connections and is completed in a shorter time.

4. Cost

In many projects, using fiberglass wall posts is more economically cost-effective.

Applications of Wall Mesh in Buildings

Wall Mesh is used in various parts of a building, including:

• Restraining interior partition walls

• Reinforcing perimeter walls

• Increasing wall resistance against earthquakes

• Preventing cracking caused by settlement or thermal stresses

• Use in renovation and retrofitting of old buildings

Advantages of Using Wall Mesh

Using Wall Mesh offers numerous advantages that have made it a popular choice in construction projects:

• Increased structural safety

• Reduced earthquake-related damages

• Increased wall lifespan

• Reduced maintenance costs

• Compliance with modern building regulations

Wall Mesh (Fiberglass Wall Post) Installation Method

Proper installation of Wall Mesh plays a decisive role in its final performance. Although this system is simpler and faster to install than metal wall posts, observing technical details and execution principles is essential to achieve maximum wall strength and safety. Below, the Wall Mesh installation steps are fully described.

1. Inspection and Surface Preparation

Before any action, the wall condition must be carefully inspected. The wall surface must:

• Be free of dust, grease, and loose materials

• Have deep cracks or local instabilities repaired

• Be completely dry and clean

If there are severe irregularities, it is better to level and smooth the wall as much as possible before installing Wall Mesh to ensure the best adhesion of the mortar and mesh.

2. Selection of Fiberglass Mesh Type and Specifications

Selecting the right mesh is one of the most important steps in installing fiberglass wall posts. The fiberglass mesh must have the following characteristics:

• Appropriate tensile strength

• Alkali-resistant (AR) for compatibility with cement mortar

• Regular and standard mesh openings

• Width and weight suitable for the wall type

In different projects, depending on wall height, material type (block, brick, terracotta, etc.), and loading conditions, mesh specifications may vary.

3. Layout and Cutting of Fiberglass Mesh

After selecting the appropriate mesh, it is time to lay it out on the wall. At this stage:

• The mesh is cut according to the wall dimensions

• Overlap between mesh strips is observed to maintain network continuity

• Around openings such as doors and windows, the mesh is installed with reinforcement and greater precision

This overlap is typically sized to ensure force transfer between different wall areas without weakness.

4. Installing the Mesh on the Wall

Fiberglass mesh can be installed on the wall using various methods, but the most common method is as follows:

• First, a thin layer of mortar or special plaster is applied to the wall surface

• The fiberglass mesh is placed on the fresh mortar and gently pressed into it

• Ensuring the mesh is completely flat, without wrinkles, and with proper adhesion to the wall surface

At this stage, precision in leveling the mesh and avoiding air bubbles or gaps between the mesh and the wall is very important.

5. Applying the Covering Layer of Mortar or Plaster

After the mesh is secured, a second layer of mortar or plaster is applied over it to:

• Completely embed the mesh within the mortar

• Create a monolithic and resistant layer on the wall surface

• Ensure uniform stress transfer across the wall surface

The thickness of this layer should be such that it provides full coverage while also preventing potential cracking.

6. Final Finishing and Curing

In the final stage:

• The wall surface is finished and smoothed

• If needed, final layers such as gypsum, paint, or decorative coatings are applied

• Proper curing of the mortar (keeping it moist or observing setting time) is performed to achieve full final strength

This stage has a direct impact on the final durability and quality of the Wall Mesh.

7. Quality Control and Final Inspection

After installation is complete, the following should be checked:

• Complete continuity of the mesh across the entire wall surface

• Absence of cracks, detachment, or weak areas

• Proper installation at corners, edges, and around openings

Final inspection ensures the proper performance of the fiberglass wall post under operational conditions and against lateral forces.

Final Words

Given the increasing importance of building safety and the continuous updating of building codes, the use of modern methods such as Wall Mesh and Fiberglass Wall Posts has become a necessity. This system is not only a suitable replacement for traditional metal wall posts but also, with its lighter weight, higher durability, and easier installation, has a promising future in the construction industry. Choosing Wall Mesh is a smart step toward increasing safety, quality, and economic efficiency in construction projects.
