Sleepers that are at least 75mm (3 inches) thick are the best to use. Anything thinner can be too weak, and can easily buckle or warp or break. Hardwoods like our Mixed Australian Hardwood Sleepers and Reclaimed Cypress are great as they are extra-strong.
Retaining walls and raised beds are just two ways that these unique timber pieces allow you to enhance your garden projects. But the question is – can you lay railway sleepers on soil? The answer is – Yes you can.
Hardwood sleepers are renowned for their durability, strength, and longevity. Oak, Karri, Jarrah, and Birch are common types of hardwood used in sleeper construction. Hardwoods have closed cell structures that make them less prone to rotting compared to softwoods.
As a rule, hardwood oak sleepers tend to last the longest naturally with an expected lifespan of around 100 years. An untreated softwood will last for between three and five years if it sits on the ground, whilst treated softwoods can last between 20 and 30 years if they are maintained correctly.
Generally speaking, a) hardwood railway sleepers last longer than softwood ones, b) tropical hardwood railway sleepers (Azobe & Jarrah) last longer than oak hardwood ones, (of which used creosote treated oak lasts longer than untreated new oak), c) new and top grade railway sleepers last longer than lower grade ones.

Yamamoto was the founder of the 13 Court Guard Squads, created to fight the Quincy during the first great war 1,000 years ago. Yamamoto, as the Head Captain of Bleach's Soul Reapers for all that time, is the oldest and most powerful Soul Reaper.
Unless, of course, you find out you are aren't. An article in the Wall Street Journal is one of many that have recently discussed a group of people called either "super sleepers" or "short sleepers"—people who actually only need fewer than six hours of sleep each night.
Fill around the sleeper with soil or sand to secure it in place before moving onto laying the next one. To fix railway sleepers to the ground, use spikes or screws designed for outdoor use to ensure they remain stable over time.
The gravel acts as a drainage layer, allowing water to flow away from the sleepers and into the ground below. It acts as a natural conduit, guiding the water away from the vulnerable wooden sleepers. This prevents moisture build-up and helps to keep the sleepers dry and structurally sound.
You can either opt for concrete, sand or gravel foundations or lay the sleepers on the soil with no official foundation. For the latter option, make sure you put down a waterproof sheet under the sleepers to avoid them soaking up moisture from the soil.
A good quality treated pine sleeper can last up to 15 to 20 years which is not a bad life span, however as soon as the15 to 20 years comes around and you have to replace that wall, then concrete sleepers instantly have become a more cost effective option.
Although you may want to place your garden sleepers straight onto the soil and give them the time to bed into the ground, we recommend putting in a layer of partially dried concrete, sand or aggregate in first to avoid water pooling around the edges of the sleepers.
Dig out area of bed to depth of 50-75mm. Start laying out the bottom course of sleepers, fixing them to the ground with metal rods.
Considering the type of soil
If you have well-draining soil, a layer of gravel or crushed stone can be an excellent option. Garden design with sleepers and gravel offers various benefits. Gravel allows for proper drainage, preventing water from pooling and potentially causing damage to the sleeper structure.
If you're placing your sleepers onto a hard surface, such as concrete or patio, they can just go straight on top, but if they're going onto the lawn or soil, you'll need to dig a shallow trench for the first sleeper to sit in.
There are many ways to cut sleepers, but we recommend using a circular saw for accuracy, precision and speed.
When fixing railway sleepers together, use steel landscaping screws as they are strong, won't corrode if they come into contact with timber treatment, and are available up to 250mm in length. With a hexagonal head they can be put in place using a power drill.
Dangers of Creosote Treated Sleepers
This treatment, once common for preserving railway sleepers, contains chemicals that can harm humans and animals. People exposed to creosote risk skin irritation or more severe conditions like cancer if they're in contact with the wood frequently.
Rot, mould and fungal growth can be prevented through wood preservative treatments. These treatments can also help to protect the sleepers against the elements. You can use any type of wood preserver for new bare wood, tanalised or pressure treated sleepers.
Softwood that is left untreated will still last around two to five years, which is why all of our softwood sleepers have been treated for longevity. We also supply hardwood sleepers, with oak sleepers ranging from 15 to 20 years and European oak sleepers lasting for 20 years.
My second was my unicorn. A perfect sleeper who as a toddler got up and put himself to bed if story time dragged on too late (“I'm go nite nite”). No middle of the night wakings (unless sick), easy naps, no parental set bedtime at any age, got himself up for school, etc.
Wolf chronotypes are the night owls of the group. As such, these folks like to stay up late and sleep in come morning. While wolves take some time to get going in the morning, they typically have more energy later in the day.
An elite sleeper is someone who needs less than six hours' sleep a night. What the hell? It's true. Approximately 3% of us are classified as “familial natural short sleepers”, which means we can wake up long before dawn and get on with our day. We can meditate, or work, or bake.
