Test Pitting

Establishing a new project and need to examine ground conditions on your site? Test pitting may allow you to assess soil conditions.

What is Test Pitting?

A test pit is a hole dug preceding construction to help guarantee ground conditions are acceptable for construction. These pits are typically 3-15 feet deep, providing geotechnical engineers with the ability to evaluate soil composition before officially excavating a site.

Test Pitting Advantages



Test pitting helps to identify potential issues before construction begins, offering enomorous potential savings by avoiding wasted efforts and preparing for construction ahead of time.



Test pitting can uncover a number of potential site problems including soil contamination, buried structures, unsuitable soil conditions, water table location, side wall instability, groundwater seepage and more.



Grassroots is capable of executing multiple test pits in one day, in many cases with a small number of crew. Excavation is far cheaper than drilling, and identifying issues can save projects from additional delays and expenses.

How Do I Know I Need Test Pitting?

New construction site
More Info

It is imperative to understand your site’s subsurface conditions before you begin operations. Test pitting may uncover issues prior to drilling, avoiding extended project deadlines and costs.

The process of test pitting may help to differentiate between bedrock and large boulders in the superficial ground. It may also help to determine the genuine particle size of large-diameter soil particles such as boulders, gravel and cobble.

Minimal intrusion

If you need to conduct minimally invasive testing on your site, test pitting is an ideal option. Hole sizes can be kept to a minimum and dug in as many places as necessary.
