BASIS Сomposite Mesh Technical Description
BASIS composite mesh is rods made of fiberglass or basalt plastic compound according to GOST 31938–2012 connected at the intersections with special thermoplastic material. The mesh is designed to reinforce concrete instead of traditional metal reinforcing mesh. It has significant advantages over metal:
- 9 times lighter
- 3 times stronger at break
- 25% cheaper
- Corrosion-resistant
- Significantly speeds up the reinforcement process (no need to fix at the construction site)
- No need to put bar chair spacers forming a protective layer of concrete
- Low thermal conductivity
- Dielectricity
The connection of the composite rods to the mesh is made according to the patented technology (BASIS composite mesh construction patent №156998, the design of equipment for mesh production patent №158113). Thermoplastic material, which joins the rods together, is also a bar chair (spacer), which forms a protective layer of concrete. For different diameter of the rod, the height of the chair is different and corresponds to the standards. The mesh-forming rod is covered with quartz sand, significantly increasing the adhesion to concrete.

BASIS Mesh Performance
The BASIS composite mesh is manufactured in cards measuring 2200x6000 mm, with the possibility of producing cards of any size with a width not exceeding 2400 mm and a length of no more than 12000 mm. The standard diameters of the rod from which the mesh is made are listed in the sizes table. According to the customer’s request, a grid with intermediate dimensions can be manufactured.
On the perimeter of the cards, there are extra amounts with a standard length of 200 mm for overlapping at the junction with neighboring cards. At customer’s request, overlapping parts can be increased to 400 mm or reduced to 10 mm within the width of the card (2400 mm). The binding of cards to each other is made with a binding wire, similar to the fastening of metal reinforcement to each other. The layout of the cards is determined by the project and in most cases is carried out in a “runaway”.
The BASIS composite mesh does not require the installation of additional “bar chair” type spacers to form a protective layer of concrete, if the reinforcement is carried on a vertical surface or a horizontal hard surface (tampered rubble, old plate, etc.). In case reinforcement of a horizontal soft surface (sand, soil, clay, etc.) is necessary, an additional installation of “bar chairs” is necessary to form a protective layer.
When reinforcing complex geometric objects, it is allowed to bend the mesh cards with a bending radius of at least 50 rod diameters from which the mesh is made.
Unloading, moving around the object and laying the mesh is done manually, without requiring any additional equipment.
Cutting cards can be carried out with an electric saw (grinder) by means of a stone-cutting diamond disc.
The BASIS composite mesh is made of materials which are environmentally friendly and do not emit harmful substances.
Application Area
Up to now, the BASIS composite mesh has revealed the following limitations: low heat resistance (up to 150°C), low modulus of elasticity. Considering these limitations, we do not recommend using the BASIS mesh for reinforcing structures that must meet special fire requirements: building intermediate concrete slabs, bridge columns, monolythic structures pylons over 3 floors.
With these exceptions it is recommended to use the BASIS mesh in a wide range of constructions: decking of bridges, foundations, concrete roads, bank protection, concrete floors, concrete chemical storages, reinforced concrete products, monolyth up to 3 floors, concrete baths, swimming pools, fountain bowls, squares, wells, sewage treatment facilities, road plates, piers, port facilities, foundation grills, underground parking lots, helipads, concrete parking lots, access constructions.
