Geoquest offer solutions to public authorities and land owners for the protection and restoration of shorelines, and developed land. At an early stage, our engineers will work with you in assessing the local situation and proposing preventive solutions to mitigate both current and future risks.
Common preventive solutions include constructing sea walls, bulkheads, dykes, complemented by revetment systems.
Sea walls
Sea walls are efficient structures to prevent coastal erosion and other damages caused by waves and storm surges. Reinforced Earth® MSE waterfront structures are designed and built to resist the combined forces of water and water borne debris which can be highly destructive during and after storms. Reinforced Earth® panels combined with proper backfill materials ensure adequate drainage, especially when the structures are subjected to rapid variations of sea levels due to high tidal amplitudes. Wave deflectors can be integrated into the panels.
T-Wall® and TechWall™ precast retaining walls can also be used for the construction of sea walls, allowing for construction under water in some situations.
Bulkheads
Reinforced Earth®, T-Wall® and TechWall™ retaining walls solutions are well adapted to the construction of bulkheads.
Dykes
Dykes are sea defence structures used for the protection of low coast and coastal lands against floods as a result of tides, wave run-up or storm surges. TerraDyke™ structures are composed of other geosynthetic components such as geotextiles, antiscour aprons and anchor tubes. Site specific primary and secondary armour layers will complement the design to provide the adequate surface protection against erosion caused by waves and currents.
In specific situations for which the footprint has to be minimised or for high structures, Reinforced Earth® dykes, either with vertical or steep faces, are the solution allowing for proper adaptation to site conditions.
Revetments and articulated concrete blocks
TechRevetment™ fabric formed concrete mattresses will provide for wave and scour protection. They can be installed in under water conditions.
Reconstruction and rehabilitation of shorelines
Our TerraDyke™ geotextile tubes and geotextile bags can be used to re-build shorelines.
“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.”
“Excellent Service, system and simple to build – would always recommend”
“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.”
“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.”
“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.”
