Geoquest’s retaining wall solutions are recognised worldwide as the preferred economical solution to ordinary and extraordinary earth retention and load support requirements for railroads
Geoquest applications include:
Retaining walls
The inherent strength and flexibility of a Reinforced Earth® (MSE) wall solution is able to meet structural, geotechnical and economical challenges for rail projects of all types, sizes and complexities. Geoquest can also design and supply alternative precast retaining wall options when challenged with more restrictive circumstances including highly restrictive rights-of-way, narrow in-fill clearances and obstructions behind the wall facing.
Cut and cover railway tunnels
Precast arches are frequently used for the construction of railway tunnels in built earth embankments or in cut-and-cover conditions. Our solutions involve a strong soil-structure interaction, associating three-hinge prefabricated concrete arches to a structural backfill. The advantages of our method include structural quality, rapid installation and the adaptability to the specific clear opening size requirements of each project.
Geoquest precast arches are especially efficient when building over existing rail tracks, below traffic, when closure during installation is either not an option or must be minimised. Reinforced Earth® (MSE) is a logical complementary technique for the construction of the spandrel walls and tunnel portal walls..
Noise protection
The construction of railways close to residential areas can be a source of noise disturbance. Geoquest designs and supplies solutions that have proven to be effective for noise protection.
Benefits of using Geoquest
Strength, resilience, durability
Strength, resilience, durability
Geoquest wall systems provide for significant load bearing, resistance to stray currents, resistance to vibrations, and resistance to deformation.
Reliability and reduced maintenance
Reliability and reduced maintenance
Standardised manufacturing for components ensures consistent and uniform quality and appearance. Our solutions have proven to be durable and to require limited maintenance.
Lower environmental impact
Lower environmental impact
Using relatively thin sections results in lesser consumption of concrete, steel, and land use, thus reducing carbon emission while minimising environmental footprints.
Engineering expertise and 120 years or more of service life
Geoquest offers unrivalled engineering expertise to provide you with the best design and supply package, coupled to commercial excellence that will make your next road development project a success.
Guaranteeing long-term life duration and minimum necessity for maintenance of the infrastructure is of outmost importance, and our designs are optimised based on the service life that is required.
