Retaining Wall Replacement

Retaining wall replacement

Old railroad-tie walls rot, dry-laid stone walls shift, and walls built without drainage eventually push over. When a wall is past repair, replacing it the right way means digging out, rebuilding the base, adding drainage and building back with materials meant to last.

Covered under retaining wall replacement

  • Removal and haul-away of the old wall
  • Rotted railroad-tie and timber wall replacement
  • Rebuilding failed block or stone walls
  • New compacted gravel base
  • New drain pipe and gravel backfill
  • Upgrading to block or stone
  • Permit and engineering help for taller walls

When a wall needs replacing

  • Rotting timbers: soft, crumbling or split railroad ties or landscape timbers.
  • Leaning along the whole length, not just one spot.
  • No real base or drainage: common with older walls built decades ago.
  • Repeated repairs that keep failing in the same place.
  • Partial collapse or a wall holding up something important, like a driveway.

What a rebuild involves

The old wall comes out, along with the soil right behind it. The crew digs a proper trench for the base, packs in gravel, sets the first course level and builds up, adding a perforated drain pipe and clean stone behind the wall as they go. Taller walls may get grid reinforcement layered into the soil. Finally the soil is put back, the top is graded so water runs away from the wall, and the site is cleaned up.

Frequently asked questions

Can you reuse the stone from my old wall?

Often, yes, if the stone is in good shape and suits the new design. Mention it in your notes so the contractor can include it in the estimate.

Do I need a permit to replace a retaining wall?

Replacing a wall can need a permit the same way a new wall does, especially if it is tall or supports a driveway or structure. Read retaining wall permits in Pittsburgh.
