These two excavation techniques involve air or water jets. Using one over the other involves assessing each situation because each soil is different. When using these methods, most of the time is spent carefully planning and preparing for the job.

Vacuum excavation uses dry air to break up the earth, and then collects it with suction power and removes it. This method is very popular because it is safe and simpler, as it does not require to be refilled with water. Moreover, the excess removed can be then reused as backfill.

It is usually used for spill cleanup, groundwater removal, debris removal, commercial cleaning, rail maintenance, or inside-the-fence work, also on large infrastructure excavations. Vacuum excavation seems to work better with loosely compacted soil or sand.

Hydrovac uses the power of water, and it is often used for cleaning tanks, tree root protection, service pit creation, debris removal, potholing, and trenching. In winter, with the use of hot water, it can be used to remove the tough frozen ground and permafrost. This method is beneficial when working around buried infrastructure, rocky soil, compacted dirt, and clay. On the other hand, it needs a constant supply of water.  Retain the services of https://www.vacuumdig.com/ for quick and safe excavation services.
