In the modern construction world, reinforcing mesh is used to strengthen concrete masonry, reinforced concrete or gypsum structures, and a special type of mesh is used in the manufacture of reinforced glass.
Reinforcing mesh properties
The main technical characteristics that form the market price of the mesh and influence the final choice of buyers are the size of the cells and the diameter of the rods of which it consists. In this case, the rods can be smooth or corrugated with a diameter of 3-5 millimeters. According to the material of manufacture, the grids are divided into metal and polymer. The former serve to strengthen cinder block, concrete or brick walls, while the latter are not in vain called plaster or painting. It is thanks to them that cracks will never appear on the surface of a freshly plastered wall. But when the reinforcing mesh is missing or laid in violation of technology, defects appear without fail. Polymer meshes are impregnated with a special alkali-resistant composition, which makes them practically invulnerable to the effects of sudden changes in temperature, corrosion, etc.
Technicalspecifications
Quality reinforcing mesh has the following characteristics:
- Excellent tear and stretch resistance.
- Helps overcome internal pressure caused by changes in humidity and temperature.
- Prevents cracking under all climatic and weather conditions.
- Increases the level of mechanical strength of the wall.
- The material is resistant to alkaline conditions, which is very important, given that almost all solutions used in building decoration are alkaline.
- Reinforcing mesh for plaster and all other types are technologically advanced and easy to use.
Reinforcing floor mesh
Reinforcement of the floor is made in cases where the layer of concrete laid on the screed is thinner than 80 mm. Despite the seeming power and strength, concrete is a rather fragile material, especially when it experiences constant vibration and dynamic loads, so the operation of a reinforced network is entirely justified. In some cases, only some sections of the floor are reinforced, or the mesh is used to reinforce the seams. Thanks to reinforcement, you can save on the amount of concrete, because this procedure allows you to reduce the thickness of the screed layer without compromising quality.
And nuances…
The reinforcing metal mesh is fastened with dowels, which are hammered in a checkerboard pattern at a distance of 20-30 cm from each other. mesh attachedoverlapping stripes. The polymer network is glued to any putty (except for the finishing one). Mesh strips are also glued overlapping or at the closest possible distance from each other (up to 1 cm) and make sure that the mesh joint does not coincide with the lines of the alleged cracks. Reinforcing mesh for floors and walls is attached between layers of concrete screed or plaster. Such a network is used when insulating facade walls with mineral wool or foam. It is frost-resistant, light in weight, non-corrosive and easy to use.
