Soil Test Pit Excavation

Understanding Culvert Installation: Proper Water Flow Starts With the Right Design

 Need soil test pits excavated for a construction, engineering, environmental, or property evaluation project? State Contracting provides reliable soil test pit excavation for residential, commercial, and development projects throughout the Portland Metro area and Southwest Washington.

Our team uses professional excavation equipment to safely expose subsurface soil conditions while working carefully around existing property features and utilities.


What Are Soil Test Pits?

Soil test pits are excavations used to expose and examine the soil beneath the ground surface.

They can be used by engineers, geotechnical professionals, environmental consultants, contractors, and property owners to evaluate subsurface conditions before moving forward with a project.

Test pits can help professionals examine:

  • Soil layers and composition
  • Soil depth
  • Ground conditions
  • Fill material
  • Rock and hardpan
  • Drainage conditions
  • Groundwater indicators
  • Other subsurface conditions


The depth, size, and location of each test pit will depend on the requirements of the project and the professional conducting the evaluation.
