"Overall definitely a great job. I had a slight issue with a few chipped bricks in the new retaining wall, but Hien quickly took care of it. Additionally he give me a good price on adding some concrete to the driveway. I particularly like that he and his team cleared away the mess each day before leaving the property. Would definitely hire them again. He priced the total job better than most that quoted me. They worked quickly to get it done in days, and finished right on schedule."

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it's repeatedly exposed to heavy rain, runoff, and excess moisture. The creosote treatment in traditional railroad ties helps resist rot and insects, but proper drainage is essential for maximizing longevity. Regular inspections and prompt repairs of minor issues can help extend your wall's useful life.
Creosote-treated railroad ties can pose health risks if used near edible plants or children's play areas. The Environmental Protection Agency (EPA) notes that creosote may be harmful to humans and wildlife. Many localities restrict or prohibit creosote-treated wood in residential settings. For garden applications, consider alternative materials like recycled plastic composite ties or lumber treated with more garden-friendly preservatives.
The ideal drainage solution depends on your specific site conditions and wall height. For most residential applications, a combination of gravel backfill and perforated drain pipe works effectively.
A complete drainage system costs between $2,100 and $6,500, though basic solutions start at $500. Proper drainage prevents water pressure buildup behind your wall, significantly reducing the risk of failure and extending its useful life.
For walls under four feet tall on relatively flat terrain, you can proceed without engineering services. However, walls exceeding four feet, those on steep slopes, or projects with unusual soil conditions require professional engineering input.
A structural engineer can design appropriate footings and reinforcement to ensure your wall safely handles the lateral soil pressure it will face.
Railroad tie retaining walls start at $15 to $25 per square foot, with most projects averaging $25 to $30 per square foot, depending on complexity and site prep. This makes them more affordable than natural stone or concrete block walls initially.
While vinyl options may cost less upfront ($10 to $15 per square foot), railroad ties offer superior aesthetics and strength. Though they require more maintenance than masonry options, their lower initial cost makes them attractive for many homeowners.
