Retaining Walls · Pittsburgh, PA

Block, stone, timber and railroad tie walls

Davis Demolition and Masonry builds and repairs retaining walls in Pittsburgh and about 40 miles around. We work in every common type: block, brick, stone, poured concrete and timber. That includes walls built out of wooden railroad ties. Most people call when the wall out back is leaning, bulging or coming apart.

Demolition is our main line of work, so a failed wall does not need two companies. We break the old wall out, haul the debris off, then build the new wall. Retaining walls sit with the rest of our masonry work on brick, block and stone. Call or text (412) 720-1866 and we will come out and look at the wall.

What We Handle

  • Block, brick, stone, poured concrete and timber retaining walls
  • Railroad tie and timber wall replacement, in ties or in block
  • Failed and collapsed walls torn out and rebuilt by one company
  • Clean stone backfill and a perforated drain pipe behind the wall
  • Weep holes through solid walls so water has a way out
  • Footings dug below the frost line to the depth the local code office sets
  • Excavator, skid steers and air jackhammers for the tear out
  • Debris hauled off and the site left clean

Why do retaining walls fail in Pittsburgh?

Water is the main reason walls go over. Soil behind a wall soaks up rain and gets heavy, and that weight pushes on the back of the wall. Engineering guidance on retaining walls calls for the fill behind a wall to be fully drained. Walls with no way to let water out are the ones that lean, bow and crack.

Pittsburgh ground makes that worse. The state Department of Conservation and Natural Resources puts the highest concentration of landslides in southwestern Pennsylvania. The same agency calls backyard landslides common in the Pittsburgh area. Steep slopes, loose soil and old slide debris set it up, and heavy rain sets it off.

Frost is the other one. Water in the ground freezes, swells and lifts anything sitting above the frost line. Old walls also fail when someone cuts into the bank below them. Loading the top with a driveway, a parking pad or a shed does it too.

Retaining wall repair, tear out and rebuild

Some walls can be repaired. A wall that has lost mortar or dropped a few units can often be opened up and put back. Once a wall is leaning, bellied out or broken through, patching only buys time. Then the answer is a tear out and a rebuild.

This is where being a demolition contractor in Pittsburgh pays off on a masonry job. The old wall comes out with the excavator, the skid steer and air jackhammers. Old brick, block and concrete get hauled off, and the bank is cut back for room to work.

The rebuild is where drainage gets fixed. We set the footing below the frost line, at the depth the local code office calls for. Clean stone goes in behind the wall, with a perforated pipe at the base to carry water out. On a solid wall we leave weep holes through the face for the same reason.

Railroad tie retaining walls and how high a wall can go

We see a lot of timber and railroad tie walls around older Pittsburgh yards. Ties were an easy way to hold a bank back, and many of those walls are decades old now. The bottom course rots, the spikes let go, and the wall bellies out and steps out of line. We still build tie walls when that is what you want.

Old ties come out with the wall and leave with the rest of the debris. EPA says creosote treated railroad ties are sometimes recycled as landscaping timbers. It also says not to burn creosote or other preservative treated wood in a residential setting. So the ties get hauled off, never burned on the job.

How high you can go is a code question. The residential code Pennsylvania uses draws the line at 48 inches of unbalanced fill. It drops to 24 inches when the wall also carries load, like a driveway above it. Above those heights an engineer works out the design, and we build the wall to it.

FAQ

Retaining Walls Questions, Answered

Common questions about retaining walls across Pittsburgh, the South Hills, the eastern suburbs and about 40 miles around. If yours is not here, call and ask.

Call (412) 720-1866

Do I need a permit for a retaining wall in Pittsburgh?
In the City of Pittsburgh, a wall 4 feet or less in height needs no building permit or zoning approval. The city measures that from the lowest level of grade to the top of the wall. Taller walls do need a permit. Outside the city, the borough or township code office sets the rule.
Do you build railroad tie retaining walls?
Yes. We build timber and railroad tie walls, and we replace old ones that have rotted out. Some people want the same look back, so ties go in again. Others use the rebuild to switch to block or stone, which we also build and price.
Can you tear out a collapsed wall and rebuild it?
Yes, and both halves stay with one company. The old wall comes out with the excavator and air jackhammers, and the debris leaves with us. Old steps or a cracked pad beside the wall can come out on the same trip as concrete removal. Then the new footing, drainage and wall go in.
What does a retaining wall cost?
Price comes down to length, height, what the wall is built of, and how hard the site is to reach. A tear out, the stone and drainage behind the wall, and the debris all move the number. We look at the job and give you a price before any work starts.
Water from the bank is getting to my basement wall. Can you help?
Often, yes. The wall holding the bank back and the wall of the house are two jobs, and sometimes both need work. We also do foundation repair and waterproofing on the house side. If the house itself is settling, a structural engineer should look at it first.
Do you work outside Pittsburgh?
Yes. We are based in Pittsburgh and work about 40 miles around. That covers the city, the South Hills, the eastern suburbs, Washington and Westmoreland counties. Bethel Park, Whitehall, McMurray, Canonsburg, Monroeville, Murrysville and Irwin are all in range.
