Utility trenches are needed for a variety of different applications. The most common applications are for compressed air, water, gas, refrigeration, or electrical needs. We often see utility trenches in automotive shops, manufacturing facilities, car washes, aircraft hangers, schools, grocery stores, hospitals, laboratories, computer rooms, electronics stores, retail stores, mechanical rooms, etc. All of these facilities have one common need, they need a utility in a location other than where it comes into the property or building. Some businesses simply need a way to access utilities so that when technology changes the wires or pipes can be updated. Others use a utility trench to allow for flexible access points to the utilities. Still others need utilities at certain "work stations" without having cables in the way of objects moving around in the building. For some it is simply to achieve a cleaner look.
There are a variety of systems for this purpose. Some are precast trench units while others are forming systems. Most offer a method of hanging pipes or conduits inside them. Make sure that the product is suited to your application as some are designed for very different needs.
