Test Pits

Test pits are one of the most common uses of hydro and air excavation. It is also commonly referred to as daylighting, locating, and sub-surface utility engineering (SUE). It is the process of digging a test hole in order to locate underground utilities of which the location is more or less unknown. Test pits are used when a contractor needs to verify the depth, size or type of underground utility. This is very effective when mapping utilities. Once an accurate map of buried utilities is made, future construction or additions can be accurately planned and added in the most efficient manner.

Ecotech can cut or core (if in concrete) a hole to locate the line … then backfill the hole according to regulations, restore the concrete or core, and provide a test hole data sheet. If needed, we will provide project management for traffic control, street cut permits and sidewalk closures. In pre-construction it provides substantial cost savings by eliminating accidental line breakage, unexpected utility relocation, change orders, environmental disasters, and community impact. Test pits are also utilized for cathodic protection procedures or to safely excavate holes for pole hole installations. When using Ecotech for test pits, you eliminate the risks associated with traditional digging methods. The water or air cuts precisely and efficiently through the soil and allows for as little material as possible to be removed in order to verify the location and grade of the utility.

Ecotech has experience with required tunneling plans that outline various processes involved in the overarching scope of work, including the creation of entry pits, shoring considerations, lighting, ventilation, confined space governance, rescue plans, and disposal issues. The only equipment needed at the actual dig area is a water or air gun and the vacuum hose. This leaves a clean job site and a virtually non-existent footprint.

Our operators have full safety training and are prepared for your unique application.
