When it comes to backfilling an underground tank, there are a number of things to take into consideration to ensure a stable grading and maintain the integrity of your tank(s).

Depending on your project, contract specifications and soil conditions, there are multiple different types of backfill materials to choose from. While backfill methods can vary from job to job, the team at Ground Solutions uses rock slinger trucks to expedite the process, saving you time and money.

  • Will the material deteriorate in water?
  • Can the material adequately support your tank(s)?
  • Is the backfill material compatible with the material from which your tank is constructed?
  • Does the material allow for rapid drainage of any water that may accumulate in the backfill?
