What can I use instead of a retaining wall?

Reinforced Soil Slopes. Reinforced soil slopes are a quick and easy construction style that uses a geotextile, such as polyethylene or polypropylene, to lock existing soil into place to create a reinforced mass.
Natural Stone Walls.
Wooden Timbers.
Gabion Walls.
Soil Bioengineered Walls.

Are railroad ties good for retaining walls?

A retaining wall allows you to turn a useless (for landscaping purposes) slope into a terraced, flat area. And perhaps the easiest way to build such a wall is with used railroad crossties.

Why do railroad ties not rot?

Railroad ties are treated with an oil-based preservative (creosote). As opposed to water, which evaporates, oil doesn’t dry. This can result in the creosote migrating out of the wood timber, especially if it’s a large, vertical piece.

How long will railroad ties last as a retaining wall?

40 years

How long do railroad ties last?

Average life of hardwood ties is 20 to 25 years.” Kevin Haugh, president of CXT Inc., provides somewhat shorter estimates of tie service life: about 40 years for concrete versus a range for wood tie life of from 8-10 years up to 15-25 years dependent on the climate and wood type.

Do railroad ties get termites?

How long do concrete railroad ties last?

”Concrete ties cost more than wood, but you can use 2,640 concrete ties per mile compared to 3,350 timber ties and they are expected to last up to 50 years,” he said. Through research, concrete-tie manufacturers have managed to overcome problems encountered in anchoring the rail.

Are railroad ties still treated with creosote?

Railroad ties are treated with chemical preservatives, such as creosote and chromated copper arsenate. Both of these chemicals are banned for residential use, and they’re potentially harmful to humans and plants. Make sure you understand the risks of using creosote railroad ties in your landscaping.

How long do creosote railroad ties last?

How long does creosote last in railroad ties? Kohler and Kunniger (2003) determined creosote levels in ties following 2, 5, 10, and 32 years in service. Although the loss rate early in life was higher, the long term straight line average at 32 years was approximately 32 percent loss.

Can you cut railroad ties with a chainsaw?

Chain saw is slow, chain gets worn very quickly. The very fastest way is with a demolition saw and a carbide blade. You will need to flip the tie over and cut from both sides. you will get a much better cut, much faster, and not need to sharpen the chain after each tie.
