How long do PERMANENT retaining walls last?

Permanent walls are typically designed to last between 50 and 100 years. The lifespan of the wall will however, be dependent on the soil and groundwater conditions at your site. Schnabel provides a number of permanent retaining wall solutions to accommodate different project conditions.

Schnabel has the expertise to help you determine the solution you need.


PERMANENT Retaining Wall Construction

Permanent tieback, soil nail and cantilevered pile retaining walls are a practical and economical solution when a permanent wall is to be built in a cut or partial cut-and-fill situation. This is particularly true when it is desirable to leave a road, structure, slope or other feature behind the wall undisturbed.

Permanent walls are typically designed to last for a long time (often 50 to 100 years). For this reason, the wall environment, including the soil and groundwater, are evaluated to determine their potential for corrosion. Schnabel’s wall construction specialists are also careful to ensure that the tiebacks, soil nails, facing connections and all the other details of the wall are designed to last for the lifetime of the wall.

To ensure the longevity of the wall, the facing is usually constructed using reinforced cast-inplace concrete, shotcrete, or pre-cast concrete panels. The wall facing can also have any number of aesthetic treatments to improve its appearance or help it blend in to the surrounding environment.

With more than a half-century of experience, Schnabel is one of America’s leading retaining wall contractors. To learn how we can help you select the best retainig wall solution for your project contact our team today.

Kennedy Interchange

Schnabel was contracted to design and build permanent retaining walls to improve traffic flow at one of the busiest interchanges in Atlanta, Georgia.

US 321

Schnabel designed and constructed 15 permanent tieback walls with a total length of over 8,500 ft. for the Tennessee Department of Transportation during the widening of U.S. 321 on the edge of the Smokey Mountain National Park.

The widening of US 321 through several miles of the Great Smokey Mountain National Park just outside of Gatlinburg, TN utilized Permanent Tieback Walls to minimize the impact to surrounding environment and preserve the beauty of this majestic area. It took a team approach between Schnabel, Blalock and Sons, Inc. and the North Carolina Department of Transportation to construct one of the largest permanent tieback wall projects in the nation.
