What Is Test Hole?

Test holes are deep, small diameter borings drilled to provide subsurface sand and gravel samples, and access for geophysical logging.

What Is Test Hole?

A test hole is a hole drilled in the ground to determine the strength, depth and water level of the soil. It is also used to check for the presence of bedrock, groundwater, and other subsurface features.

Test holes are often used in construction, engineering, and environmental projects. There are several methods of drilling test holes, including auger drilling, rotary drilling, and core drilling.

The type of drilling method used will depend on the project requirements and the nature of the ground. Test holes are typically drilled to a depth of 30 feet (9 meters), but can be deeper if necessary.

The hole is then filled with water and the water level is monitored over time. This allows for the determination of the water level, which is important for understanding the groundwater conditions in an area.

The hole is also used to collect soil samples for testing. The samples are usually collected at different depths within the hole.

These samples can be used to test for the presence of contaminants, the strength of the soil, and other properties. Test holes can be a valuable tool in a variety of projects.

They can provide important information about the subsurface conditions of an area and can help to ensure the success of a project.
