The Story
Treated softwood railway sleepers measuring 100mm x 200mm x 3.6m are a reliable, cost-effective solution for raised beds, retaining walls, and garden landscaping. Pressure treated with Tanalith E, each sleeper is planed to square edges for consistent dimensions and a clean finish on site.
Specifications
| Property | Detail |
|---|---|
| Material | Softwood |
| Treatment | Tanalith E pressure treatment |
| Finish | Planed, square-edged |
| Nominal Size | 100mm x 200mm x 3.6m |

What it's used for
- Raised vegetable and flower beds, providing a defined, long-lasting border
- Retaining walls and terracing on sloped gardens
- Garden edging and pathway definition
- Rustic seating, steps, and low-level landscape features
Fitting and handling
Each sleeper weighs approximately 27kg, making them manageable for most two-person installations without specialist equipment. When stacking on site, store flat on a level surface with cross-bearers to allow air circulation and prevent distortion. Fix sleepers using galvanised timber screws or rebar pins for ground-contact applications, ensuring any cut ends are re-treated with an end-grain preservative before installation.
FAQ
Are these sleepers safe to use in a vegetable garden raised bed?
Yes. Tanalith E is a copper-based preservative approved for use in amenity and domestic settings, including raised beds. It meets EU biocidal regulations and is widely used in domestic landscaping across the UK. If you are growing edible crops directly against the timber, lining the inside face with a root barrier membrane is a straightforward precaution.
What is the difference between a new softwood sleeper and a reclaimed hardwood sleeper?
New treated softwood sleepers are machine-planed to consistent dimensions, making them easier to cut, stack, and align. Reclaimed hardwood sleepers can vary significantly in size and may contain contaminants from previous railway use. Softwood sleepers are lighter and generally more practical for garden DIY projects.
Can I cut these sleepers to length on site?
Yes. These sleepers can be cut with a hand saw or circular saw fitted with a suitable blade. Always apply a brush-on timber preservative to any cut face before installation to maintain rot resistance at exposed end grain.
