Bridges


By building stable walls capable of bearing heavy loads with little settlement, Reinforced Earth® can be extended to abutments directly supporting bridge decks.

These structures are located at both ends of the bridge and clearly spotlight the technology's unique capabilities. Although the general principle of Reinforced Earth® remains the same, the settlement restrictions, loads and stresses involved with this type of structure are extremely high.

Thanks to the flexibility of the Reinforced Earth® technology, bridge abutments can be built on compressible ground, mostly without any need for deep foundations. Reinforced Earth® boasts many advantages for this type of construction. Reinforced Earth® integral abutments eliminate or reduce the need for structural bearings and expansion joints, which significantly reduces operating and maintenance costs.

With many bridges, the central section of the bridge can be supported directly by the reinforced earth abutment, which eliminates the need for piers and piles to support the bridge's central section.

Such true abutments are an excellent solution when foundation soils are compressible. If the foundation soil is highly compressible, different technologies can be combined with Reinforced Earth® to stabilize the entire structure.
