Mountainous areas allow very limited options when developing infrastructure that may be linear, such as roadways and railways, or when developing residential areas vulnerable to avalanches. Anticipation and preparation is key. We have developed several engineered solutions using Reinforced Earth® MSE walls which have proven to be very effective as part of avalanche protection applications.

Avalanche barriers, splitter walls & catching dams

Avalanches produce tremendous amounts of energy that require solutions that absorb and diffuse energy. The construction of embankments faced with steel mesh are an excellent option to build avalanche barriers, splitters and catching dams with facing angles that can vary from 34° to 75°. Geoquest offer the TerraTrel® and GeoTrel® engineered solutions, built of steel mesh facing with soil reinforcements comprised of either steel or geosynthetics and have the advantage of being made of lightweight elements that are easily transportable and that do not require specific lifting machinery for installation.

Sheds and galleries

Avalanche protection sheds and galleries using precast arches, have proven to be efficient for avalanche protection applications. Adjoining retaining walls built within narrow excavation limits are often designed using TechWall™ or T-Wall®.

Long-term savings

Reinforced Earth engineered avalanche barriers and splitter walls are more economical than traditional solutions, in addition to being highly durable and easy to install, with little or no maintenance requirements.

“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
