Retaining Wall Planner

Enter the length and height of a wall and see courses, block, drainage stone and when an engineer is needed.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual site, soil, access, local rules and conditions. Only a site visit can confirm what your property needs, and we give you a clear price before any work begins.

How it works

Four quick steps.

  1. 01

    Enter length and height

    Of the exposed wall face, in feet.

  2. 02

    Pick the block size

    Small, standard or large units change the course count and block total.

  3. 03

    Say what is above the wall

    A slope, a driveway or a building raises the stakes.

  4. 04

    Read the plan

    Courses, block, caps, drainage stone and engineering flags.

Tips

  • Drainage behind the wall matters as much as the wall itself.
  • Taller walls need geogrid and often engineered plans.
  • Plan steps and planting with the wall, not after it.
Questions

About this tool.

When do I need an engineer?

Taller walls, walls under driveways or buildings and walls with slopes above usually do. The tool flags the common cases.

Is this a design?

No. It is a planning guide. A real wall needs a site visit and, in many cases, engineered drawings.

Why bury the first course?

It locks the wall into the ground and keeps the base from shifting.
