Suction Excavation works by using a high throughput of air (22,000 and/or 25,000 cubic meters per hour). This high velocity air current removes the material to be excavated through the suction intake attachment. This heavy material is deposited in the vacuum/holding container and any further smaller elements are eliminated by contact with reversing plates within the main air duct. Any remaining small particles are captured in a micro filter system ensuring that the final air flow escaping through the system is clean and dust free.

The suction excavator is designed to dig a hole in the ground, but to do so in such a way as to prevent damaging anything buried in the ground such as utilities.

By utilising either high pressure air or water (water used in more difficult soil conditions) to penetrate expand and break up the soil. As the ground is loosened, it is removed by suction and stored in a vacuum/holding container, either to be used as backfill or to be hauled away for disposal. In this way you can expose the buried utility.
