Planning and placing buried bridge structures is challenging for engineers and builders.<\/h2>\n
Reinforced Earth is well known not only for specializing in soils-structure interaction modelling, but also for developing materials specifications and recommendations necessary to build these buried structures quickly, safely, and with predictable resilience, performance and durability.<\/p>\n<\/div>

<\/div><\/div><\/div><\/div>Reinforced Earth offers tailored, pre-engineered, prefabricated material solutions for your project specifics. Working together, your team and our Reinforced Earth bridge specialists will determine the best choice between our TechSpan\u00ae precast arch<\/a> selections (visit precastarches.com<\/a>), our TechBox\u2122<\/a> variations, and Reinforced Earth\u00ae walls<\/a> to provide the most economical solution for your buried bridge structure.<\/p>\n Buried bridges normally come in the form of arches or boxes. These structures are designed to be flexible and to accommodate differential movement and built to support heavy dynamic loads induced by vehicle trafficking such as trucks, trains, and aircraft.<\/p>\n As a cost-effective alternative to cast-in-place, the applications can address the need for:<\/p>\n TechSpan\u00ae<\/a> is a proven solution that has been used for the construction of hundreds of buried bridges around the world. Our precast concrete arches come in a wide variety of design options due to the large catalogue of shapes available. We have designed for single spans as wide as 25m. In the event of the maximum offsite-produced span being restrictive for transport, it is also possible to manufacture onsite, or to build a multi-span arch bridge.<\/p>\n TechBox\u2122 precast concrete boxes<\/a> are suitable for applications such as short-span bridges or stream culverts, able to withstand flows of water and heavy loads. A Reinforced Earth buried box structure can also be designed and manufactured using our TechWall\u2122 solution<\/a> combined with a segmental precast concrete over-bridging \u201clid\u201d to form a composite buried box.<\/p>\n Reinforced Earth\u00ae<\/a> can be used to build Mechanically Stabilized Earth (MSE) walls to form \u201cbox\u201d bridge openings or built along the sides of the precast concrete arches or boxes as wing walls or spandrel walls. Reinforced Earth\u00ae<\/a> can be designed using steel or geosynthetic soil reinforcement, therefore accommodating any backfill constraints.<\/p>\n Our operations teams have expertise at delivering aesthetic form liner finishes and customized artworks<\/a> integrated within our structures. We also design and furnish precast copings, collar beams, barriers and various trim features<\/a> which can be detailed into our design and supply package.<\/p>\n<\/div> Our flagship technique, Reinforced Earth\u00ae, is based on the principle of the friction between soil and reinforcements creating a permanent and predictable bond. At the origin of all mechanically stabilized earth (MSE) walls on the market today, we are continuously perfecting this ingenious technique.<\/span> A precast retaining wall system, TechWall\u2122 combines the advantages of counterfort with the quality and effectiveness of precast concrete. A great fit for sites with soil bearing capacities allowing for shallow foundations, TechWall\u2122 can also be combined with piling solutions to accommodate different types of soil. Sustainable, cost-effective, and quick to install, TechWall\u2122 may just be the ideal solution for your project needs. Resulting from decades of research and development, TechSpan\u00ae is a buried precast concrete arch system designed to accommodate high fills, heavy live loads, and alternating loading conditions. With a small footprint and easy and quick to install, TechSpan\u00ae is ideal for mining, industrial, and railway applications, it is gaining popularity in many different markets.
