The walls of industrial, residential and other buildings are built with the help of different materials – stone, brick, aerated concrete, foam blocks, cinder blocks, while using classic cement mortar or special glue. In the first case, the thickness of the seams is about 6 mm, in the second case, this index decreases in 2 times.
Another mandatory attribute in the laying of walls is a composite fiberglass rebar. Nonmetallic rebar for walls performs two tasks simultaneously:
1. Horizontal masonry rebar to create a complete structure.
2. Ensuring the uniformity of the thickness of the seam between the rows (application as “beacons”).
Due to the fact that builders use fiberglass rebar with a diameter of 4 mm, the thickness of the seam is minimal. To achieve an enhanced effect, it is desirable to equip each row of masonry with rods. Additional rebar requires a places under the window apertures, sections of walls, where the window and door lintels are mounted. Particular attention should be paid to structural fragments that experience increased load.

Why fiberglass?

Composite fiberglass rebar is a non-metallic core characterized by the following advantages:

  • a small specific weight, which minimizes the load on the walls and foundation;
  • low thermal conductivity eliminates such a problem as cold bridges;
  • durability is achieved due to the resistance of the composite to corrosion;
  • dielectricity, that is, the non-conductance of currents;
  • resistance to chemical elements – acid and other corrosive environments;
  • radio transparency – protection from the formation of radio interference.

Another plus of fiberglass rebar is the economic feasibility of use. Products are sold in coils, which reduces the consumption of material and reduces transportation costs.

Some rules for the application of composite cebar

Employees of the company “MRG-Composites” have extensive experience in the sale of non-metallic rebar, therefore, if necessary, will consult on the technical characteristics of the material and the rules for use when laying walls.
Let us consider only a few points. For example, it is desirable to reinforce the outer walls not with rods, but with a fiberglass mesh. Mounted as ready-made structures as rebar, connected directly on the construction site. The construction of multi-layer walls with thermal insulation material implies the use of flexible bonds from the composite. The length of the connecting elements is selected individually.

The importance of flexible connections in walls masonry

With the help of flexible connections made of fiberglass, the wall elements are securely fastened together with each other and with waterproofing or thermal insulation materials. Fiberglass increases the structural strength of the structure by bending and stretching. It also provides resistance to the alkaline environment of concrete, glue and cement mortars. And one more reason for assembling composite, rather than metal products, is the uniformity of the thermal resistance of the wall or other building element.
To achieve the maximum result of flexible connections should be at least 4 pieces per 1 sq. m. This requirement refers more to blind monolithic walls, in other cases this indicator may vary. When working with reinforced concrete walls, the step of assembling flexible ties of fiberglass is 500 mm, both vertically and horizontally. In the problem areas of the wall (openings, deformation seams, etc.), the pitch is reduced to 300 mm.
