Geoquest’s Reinforced Earth® MSE retaining walls are a tested solution for building earth dams, dam crests and abutments. Building a vertical or sloping Reinforced Earth® MSE structure will dramatically reduce the volume of backfill when compared with traditional profiles.

The Reinforced Earth® MSE solution has been used to build various types of dams and structures associated to dams:

  • Embankment dams
  • Overflow dams
  • Saddle dams
  • Check dams
  • Dry dams
  • Dam extensions
  • Intake structures
  • Outlet structures

Flexible construction solution for dykes and reservoirs

TerraDyke™ concept developed by Geoquest is a customised engineered solution particularly well adapted to the construction of dykes and reservoirs in coastal and inland environments.

The TerraDyke™ technique uses geotextile tubes at its core and utilises other geosynthetic components such as geotextiles, waterproofing membranes, drainage geocomposites and site specific erosion protection against currents, waves and run off.

Advantages of TerraDyke™:

  • Uses geosynthetic materials
  • Formed using locally available fill materials
  • Can reduce footprint size with vertical faces

Protecting and preserving

  • TechRevetment™: Fabric-formed concrete mattresses for protecting river or sea-facing sides of levees and dykes; suitable for underwater installation.
  • TerraGreen®: Erosion protection blankets and turf reinforcement mats for landward sides, offering greening support.
  • ArmaWeb®: Geocells for erosion control and vegetation support on landward sides.
  • TerraTextile™: Geosynthetic solutions for filtration and separation.
  • TerraFlow™: Geosynthetic products designed for drainage solutions.
  • TerraLine™: Waterproofing geosynthetic, can be used in conjunction with MSE walls.

“I have worked with Geoquest on two previous projects and both times have exceeded my expectation. I find the product easy to work with, quick for construction and a good final product, looking the part. There is a good turn around time from the Geoquest team and always have answered any queries I have had. I would definitely use them again.”

Patrick Goodwin, Section Engineer, Graham Construction

“Excellent Service, system and simple to build – would always recommend”

J Millar, Project Manager, Osborne Infrastructure

“The design and materials supplied by Geoquest for the new Velindre Cancer Centre bridge was excellent, providing a high-quality product at a competitive price. The technical assistance with both the design and installation was highly commendable leading to a very high standard structure upon completion.

We would thoroughly recommend Geoquest for any retained earth projects and will recommend early engagement on future projects to utilise their vast technical knowledge for value engineering.”

Tom Morris, Project Manager, Walters

“Having used Geoquest for the provision of a reinforced earth wall system on a new highway scheme I found them to be very helpful and easy to work with in the run up to construction and also throughout the construction. The quality of the final product was very good and looks well now that the work is complete and open to traffic.”

Dave Mantle, Senior Site Manager, Octavius

“Osborne Infrastructure selected Geoquest due to their reputation and expertise. They delivered on both. They provided both the design and the fabrication of the reinforced earth abutments for the M27 Romsey Road bridge on time and within budget. Design changes due to unforeseen site conditions were dealt with efficiently with expert advice on hand to ensure we produced the right solution for our client Highways England.

I would be more than happy to recommend Geoquest and would make them my go to specialist for this type of work.”

M Whale, Senior Site Manager, Osborne Infrastructure
