You can see our walls in commercial developments; residential neighborhoods; and along highways, freeways, and bike/hiking paths throughout Minnesota and the surrounding five states. We provide quality service across the Upper Midwest.

A note about Construction Review

Construction review is a critical part of segmental retaining wall construction. It protects all members of the project team (i.e., the owner, design engineer, contractor) from incorrect wall construction. Poor wall construction is the primary reason retaining walls fail. Utilizing the construction review services from us can help.

The following wall elements should be verified by the retaining wall engineer prior to and during wall construction:

  • Foundation Materials and Preparation
  • Drainage Aggregate
  • Segmental Retaining Wall Blocks/Wall Facing
  • Wall Backfill
  • Drainage Aggregate
  • Geogrid Reinforcement
  • Geotextile and Drainage Pipe
