Why composite

Replaces wood, creosote and concrete.

Wooden sleepers impregnated with creosote are being phased out across the EU — they leak toxins directly into the ground. Concrete sleepers are strong but impractical: if a single sleeper needs replacing, often the entire track section must be lifted and redone.

Our composite sleeper solves both problems. You can replace one sleeper at a time in existing tracks, without special machinery. And with a service life of over 50 years, it is the most cost-effective alternative on the market.
