Infrastructure built in marine environments are exposed to many risks that may cause damage and affect long-term performance. Whether immersed or in close proximity to shorelines, it is possible to mitigate the risks associated with extreme weather, rising sea levels and exposure to sea water.

Sea walls

Our protective and confinement walls are designed to protect infrastructure built near the shoreline or riverbank. We design walls with integral wave and flood deflecting features and water-channeling and drainage systems.

Reinforced Earth® wall solutions can be designed and dimensioned with galvanized steel strips or with geosynthetic reinforcements, offering more options to reach expected service life and optimal performance.

Our TechWall™ precast cantilever wall and T-Wall® precast gravity wall can also be used to build sea walls. These alternatives allow for more design options, for instance when building in narrow spaces or for construction directly in water. Easy and quick to install, while ensuring for long-term service life, our precast retaining walls are an excellent fit to marine environments.

Coastal protection

For coastal protection and coastal damage control, our TerraDyke™ geotextile tubes are commonly used to build self-standing gravity barriers. Protective levees, groynes and breakwaters provide protection to nearby construction sites, or to permanently mitigate risks related to unpredictable sea levels. They can also be used for shoreline reconstruction and rehabilitation.

Scour and erosion control

Geotextile formed concrete mattresses, Articulated Concrete Block (ACB) mattresses can be used to protect shorelines from erosion and scour.

Pipeline and cable protection

TechRevetment™ geosynthetic formed concrete mattresses and Articulated Concrete Blocks are often used to cover and shelter pipeline and cable networks from risk of damage.

“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
