Sleeper steps need a firm base, secure restraint and somewhere for water to drain. The right build depends on the ground and how heavily the steps will be used.
For light garden use, start with compacted stone
Firm compacted stone can form a level, free-draining base for simple garden steps. Set the sleeper that forms the riser, check it is level and restrain it before finishing the tread behind it.
For heavier use, move towards a more substantial base
Concrete or mortar can provide a firmer base for frequently used steps. Where the sleeper needs positive fixing to suitable concrete, use Sleeper Base Anchors.
Do not rely on weight alone
Use support spikes, brackets or structural timber screws as appropriate to stop sleepers rocking, tipping or creeping forward.
Wet timber steps can become slippery
Warn for this at the planning stage. Anti-slip decking oils, strips and other products are available, but there is no single solution we recommend for every sleeper step. Choose and research a system that suits the finished surface and the way the steps will be used.
Treat cut ends
If you cut the sleepers, always treat the fresh end before fitting.
Our 195 × 95mm garden sleepers come in several lengths, so choosing the right stock length can reduce cutting.
