Heavy Duty Fiberglass Mesh is a woven reinforcement fabric manufactured from continuous fiberglass yarns with a high coating content for improved durability in cementitious and bitumen-based systems. Compared with standard fiberglass mesh, this grade features a higher fabric weight, increased tensile capacity and greater dimensional stability under mechanical loading.

The mesh is intended for applications where conventional reinforcement fabrics cannot provide sufficient strength. Typical uses include thick render systems, concrete reinforcement, asphalt overlays, industrial flooring and heavy-duty repair work.

The combination of fiberglass reinforcement and polymer coating helps the mesh maintain its mechanical performance in alkaline construction materials while providing reliable bonding with mortar, cement, asphalt and similar compounds.

Material Performance

Heavy Duty Fiberglass Mesh functions as a tensile reinforcement layer inside cement, mortar or asphalt systems. Once embedded, the open-grid structure transfers localized stresses over a larger area instead of allowing them to concentrate at individual points.

 

During curing, service loading or thermal movement, the mesh helps reduce stress concentrations that may lead to shrinkage cracking or reflective cracking. In flooring and pavement applications, it also improves dimensional stability of the reinforced layer and contributes to longer service life.

 

Performance depends on mesh weight, coating quality, embedment depth and the design of the complete construction system.

• High fabric weight for demanding reinforcement applications

• Increased tensile strength compared with conventional fiberglass mesh

• Good dimensional stability during installation and service

• Alkali-resistant polymer coating suitable for cement-based materials

• Compatible with mortar, concrete, asphalt, waterproofing compounds and resin systems

• Good resistance to moisture, weathering and normal construction chemicals

• Available in different mesh openings, roll widths and coating specifications

Typical Applications

Heavy Duty Fiberglass Mesh is commonly specified for reinforcement in applications such as:

• Thick cement render and plaster systems

• Concrete repair and strengthening

• Industrial flooring and concrete slabs

• Asphalt pavement rehabilitation and crack mitigation

• External wall insulation systems requiring high impact resistance

• Waterproofing membranes and roofing systems

• Tunnel, bridge and infrastructure maintenance projects

Selection of mesh weight and aperture should match the mechanical requirements of the application.

Available Specifications

Heavy Duty Fiberglass Mesh can be supplied in a range of standard and customized specifications, including:

• Fabric weight

• Mesh opening

• Tensile strength

• Roll width

• Roll length

• Coating type

• Yarn specification

• Color and packaging

Custom production is available for project-specific reinforcement requirements, including higher tensile grades, special coating formulations and non-standard roll dimensions.

For optimum reinforcement performance, the mesh should be fully embedded within the reinforcing layer and positioned approximately in the outer third of the coating thickness where tensile stresses are generally highest. The substrate should be clean, stable and properly prepared before installation. Final performance depends on correct installation procedures as well as the properties of the surrounding construction materials.
