ViaWall

There are three types of Mechanically Stabilized Earth (MSE) systems:

ViaWall A
ViaWall B
ViaBlock

 

ViaWall A

ViaWall A is a retaining wall system, in which reinforced concrete panels form the facing part of the wall, while galvanised steel reinforcing mesh or uniaxial PEHD geogrid forms the reinforcing part in the embankment.

The panel is made of concrete (grade C30/37) reinforced with steel (class A-III or higher). The system consists of typical panels with the following dimensions: 150x150x15 cm (18 cm) and 150x78,5x15 cm (18 cm) (width x height x thickness). It is possible to form panels with non-standard dimensions. Non-standard panels can have any shape, however the maximum size of a panel cannot exceed 220x150x15 cm (18 cm) or 150x220x15 cm (18 cm).

Reinforcing meshes:

Reinforcing meshes are made of steel bars (class A-III or higher), ribbed or smooth, with diameters from 6 to 12 mm. Mesh is protected against corrosion by a zinc layer with a coating weight of min. 600 g/m2.

U-bolts:

Inseparable elements of the system are U-bolts that fasten reinforcing mesh to panels. U-bolts are protected against corrosion by a zinc layer with a coating weight of min. 600 g/m2.

Advantages of using the ViaWall A system:

  • possibility of forming any geometric shapes
  • easy to install and impervious to weather conditions
  • installed with the use of light equipment
  • possibility of using panel faces with various architectural textures

Applications:

  • Retaining Walls
  • Headwalls and Wingwalls
  • Bridge Abutments
  • Crusher Ramps/Walls

 

ViaWall B

ViaWall B is a retaining wall system, in which steel reinforcing meshes form the face and reinforcement part of the embankment.

ViaWall B system includes two types of reinforcing meshes::

  • main L-shaped mesh, which acts both as the face and the anchoring element
  • auxiliary mesh, which forms only the face of the wall; spacing between bars: 100x250 mm

In order to protect the mesh against corrosion, all elements of the system are covered with a zinc layer with a coating weight of min. 600 g/m2.

Backfill:

A separating geotextile is used between the back¬fill in the facing part of the wall with a grain size of 80/250 and the back¬fill in the reinforcing part with a grain size of 0/80.

Advantages of using the ViaWall B system:

  • quick and economical retaining wall system
  • easy to install and impervious to weather conditions  
  • thanks to the use of natural stone in the facing part, the system perfectly integrates with the natural environment, e.g. in mountainous areas

Applications:

  • Retaining Walls
  • Headwalls and Wingwalls
  • Bridge Abutments

 

ViaBlock

ViaBlock is a retaining wall system, in which the face of the wall is made from ViaBlock concrete blocks combined with a geosynthetic reinforcing the embankment.

Blocks constitute an integral part of the system and can be used with other elements of the system, e.g. uniaxial polyethylene geogrid and polyethylene connectors (T-clip).

There are two types of concrete blocks in the ViaBlock retaining wall system:

  • wall blocks (active, passive)
  • blocks crowning the wall

Applications:

  • Retaining Walls
  • Headwalls and Wingwalls
  • Bridge Abutments

Advantages of using the ViaBlock system:

  • low cost of building a retaining wall
  • quick and easy installation
  • possibility of forming walls with various shapes (concave or convex arch)
  • possibility of making blocks in different colours
