This composite fiberglass mesh with 2.8 mm diameter and 20 x 20 cm openings represents a step up in strength compared to thinner versions, while retaining all the advantages of polymer materials. Instead of metal, it uses fiberglass bound with epoxy resin and twisted into a ribbed profile that holds securely in concrete. The material is non-corrosive, resistant to salt water, alkalis, and acids, weighs significantly less than steel, yet resists tension excellently. The 2 x 25 meter sheet provides 50 square meters of reinforcement with minimal overlaps. The twisted surface provides bonding with concrete no worse than that of steel rebar.
The mesh is suitable for use in aggressive environments where steel quickly deteriorates. It is an ideal choice for marine structures: breakwaters, piers, docks, seawalls. It is also used in swimming pools, wastewater treatment plants, water and chemical tanks, and chemical manufacturing facilities. In civil construction, the mesh can be used for foundations on wet ground, road slabs in areas with high groundwater levels, floors in workshops with aggressive environments, parking garages where deicing salts are applied. It is also suitable for reinforcing concrete elements exposed to moisture: paving slabs, curbs, garden paths.
The main advantages are complete rust resistance and very low weight. Fiberglass leaves no rust stains on concrete and does not deteriorate from within. It does not conduct electricity and creates no interference with radio signals. The mesh is so lightweight that it can be easily carried and laid by one person. If construction is taking place near water or in an aggressive environment — composite mesh will outlast steel and will not require demolition and replacement after a few years. The 2.8 mm diameter provides an additional safety margin compared to thinner alternatives.
