Composite masonry mesh ROCKMESH

Corrosion of steel concrete reinforcement occurring due to moist environment, chemicals or salts can be a reason for extensive damage and failure of reinforced concrete structures, such as concrete covers, areas characterized by increased moisture, harbor works, floors at manufacturing facilities, highway concrete coatings, etc.
Specific problems arising due to the use of metal reinforcement led to search for alternative solutions. ROCKMESH composite mesh is proposed by Galen LLC as one of the best substitution products for steel construction elements.

Product description
Composite mesh ROCKMESH is manufactured from BFRP or GFRP (basalt- and glass fiber reinforced polymer material) ROCKBAR composite rods which are placed in two directions perpendicular to each other and fixed at the intersections.
ROCKMESH is supplied as a ready-to-use solution: in rolls or sheets thus speeding up construction operations.

Fields of application:

Civil engineering
1. Reinforcement of precast concrete structures: interior and exterior wall panels, including multi-layer concrete (sandwich) panels, ceiling panels, beams
2. Reinforcement of concrete floors
3. Reinforcement of masonry and stone buildings and constructions
4. Reinforcement of ornamental gypsum articles
5. Reinforcement of other concrete and gypsum construction elements

Industrial engineering

1. Reinforcement of precast concrete structures: interior and exterior wall panels, including multi-layer concrete (sandwich) panels, ceiling panels, beams
2. Reinforcement of concrete floors
3. Reinforcement of hydraulic, coastal structures
4. Reinforcement of masonry and stone buildings and constructions
5. Reinforcement of ornamental gypsum articles
6. Reinforcement of other concrete and gypsum construction elements

Highway engineering
1. Reinforcement of road panels
2. Reinforcement of highways, bridges
3. Highway and railroad fencing

The mesh is mainly used in civil and industrial construction, as well as in corrosive and moist environments, in chemical industry, sewage treatment plants, agricultural industry, landfills, storage houses, hydraulic structures.

The masonry meshs advantages:

  • high tensile strength: composite armature is capable of withstanding higher loads in tension, bending and tearing out of a wall than metal one, i.e. it is 3 times stronger;
  • high corrosion- and chemical resistance: excellent capacity to resist the impact of chemicals, salts and corrosion process even in high moisture & aggressive mediums;
  • low mass: weight of the most common metal mesh (50*50*3 mm, 0,5*2 m) is 2.22 kg/m2, a similar mesh made of composite material weighs 300-360 g/m2, i.e. it is 6 times lighter;
  • low thermal conductivity: 0.46 W/m2 of a composite mesh, and 40-60 W/m2 of a metal mesh, i.e 100 times higher than that of metal mesh. This means that metal mesh in walls act as thermal bridges and reduce the thermal efficiency of a building. Composite mesh helps to eliminate this disadvantage;
  • reliable & durable: according to investigation reports by The University of Sheffield (The UK) the coefficient of strength reduction in moisture conditions within 100 years equals to 1.25. This corresponds to strength retension of 79.6%;
  • high adhesion with concrete due to sand coating;
  • dielectric;
  • non magnetic;
  • eco-friendly: emissions of carbon dioxide during production of composite mesh is 40 times lower than that for metal one;
  • low elasticity modulus allows to damp vibration smoothly;
  • retains its shape at concrete structure damages that prevents further structure failure.

Recommendations

We do not recommend to use the product for reinforcement of bearing columns (economically unsound). If you have any questions, please do not hesitate to contact the technical expert in Galen Viktor Valerievich Nikolaev, phone number: +7 (8352) 66-23-22.

Implemented projects

Composite masonry mesh ROCKMESH was used for construction of multi storied housing complex in South coast residential district in the city of Krasnoyarsk.
