Deadmen for a 2-Foot Timber Retaining Wall: Spacing & Necessity

Building a 2-foot, 6×6 pressure-treated timber wall along a driveway? Deadmen (tiebacks) are essential—even at this height.

Why Deadmen Matter

Timber walls lack the mass of stone or concrete. Without tiebacks, soil pressure eventually bows or topples them. Deadmen anchor the wall into the backfill.

Spacing Rule

Install deadmen every 8 feet along the wall length. Use 6×6 timbers of the same length as the wall height (2 feet), perpendicular to the wall, buried in compacted backfill.

Bonus Tips

• Use galvanized or stainless spikes/rods—corrosion kills connections
• Backfill with free-draining gravel, not native clay
• Install a perforated drain pipe at the base with weep holes every 6–8 feet

A 2-foot wall looks simple. Treat it like engineering, not stacking lumber.
