Dedicated applications for airports
Design engineers for airport infrastructure are regularly challenged with finding technical, yet economical and sustainable solutions that can overcome difficult constraints, such as:
- Restrictive rights-of-way
- Low overhead clearances
- Narrow travel lanes and pathways
- Complex alignments and geometry
- The capacity for structures to carry heavy loading
Geoquest’s portfolio of retaining wall solutions, arches and geosynthetics meet these challenges.
Reinforced Earth® MSE walls, Geoquest’s flagship solution is the engineer’s first choice for landside vertical grade separations and bridge abutments as has been demonstrated on hundreds of airport projects worldwide. Where reinforced soil slopes or embankments are required, then our slope solution is recommended.
Whether it’s landside or airside, Geoquest can offer solutions to cover;
- Tramway and people-mover guideways
- Taxiway bridges and underpasses
- Retaining walls for elevated aircraft parking aprons
- Retaining walls for elevated runways and extensions
- Utility tunnels and escape tunnels
- Runway and taxiway subgrade stabilisation
Runway extensions can entail building massive MSE structures in challenging terrain, even water. In the USA, Geoquest has designed and supplied walls supporting elevated runway extensions up to heights of 46m.
