Tartu flygplats

Tartu, Estland

A mechanically-stabilised layer using TriAx® geogrid provided a strong foundation for a runway extension at Tartu Airport. 

Benefits

  • Innovative approach to dealing with difficult ground conditions
  • Fast construction ensured the runway opened on time
  • Flexurally stiff foundation to prevent differential settlement
Client's Challenge

Excavations for a runway extension at Estonia’s second international airport revealed very weak and variable saturated ground. Client Tartu Airport needed a solution that provided a strong foundation for the runway pavement; one that could be implemented quickly and easily.

Tensar Solution

Tensar’s TriAx geogrids were incorporated in a granular mattress placed on the weak ground to form a mechanically stabilised layer, providing a flexurally stiff foundation to the subbase and the runway pavement structure above.
