Retaining wall made simple with precast concrete

Compared to conventional construction methods, Fortrac Panel system solutions save you construction time through elimination of costly foundations, the rapid construction of the geogrid-reinforced soil body and the simple installation of prefabricated concrete elements. Depending on the requirements, the precast concrete elements can actively contribute to the overall stability of the supporting structure, such as an abutment, or can be attached to the reinforced earth body at a later time. In active construction, the facing elements are actively loaded by the earth pressure and are both formwork and visible elements at the same time. In the passive system, the geogrid holds the entire earth pressure, and the concrete facing has a purely visual and protective function. A major advantage of the passive construction method is that, in difficult ground conditions, you can wait for possible subsidence and deformation and install the concrete facing with a time delay in relation to the supporting structure. Our engineers will be pleased to support you in designing the back-anchored retaining walls.

System benefits

  • Rapid erection with slender precast concrete panels
  • Cost-effective alternative to concrete-only solutions
  • Less labour and plant requirement
  • Project-specific solutions with structural or
    purely cosmetic/protective facings
  • Tied-back sheet piling as a further option

Our system models

Active model

  • Panels acting simultaneously as formwork and finish
  • Outer skin forming part of structural system
  • Rapid on site erection (also thanks to large intervals between geogrid layers)
  • Fewer geogrids/geogrid layers
  • Connectors can be used to accommodate settlement

Passive model

  • Particularly suitable for settlement-prone soils
  • Freedom from restraint and deformation due to phased installation
  • Minimisation of later settlement, e.g. by advance surcharging
  • Damage to panels has no impact on structural stability
  • Individual panels easily replaceable if damaged

Component kit
