Installation & Construction

Now, on to the topic of the day: 

When It Comes To Inground Swimming Pool Construction: What Is The Best Material To Use When Backfilling A Fiberglass Pool? 

In the following video, taken from our 2016 River Pools Powered by Thursday Pools Dealer Conference, I share our experience over a 15 year period where we installed over 1,000 fiberglass pools, some using sand and some with stone backfill material.  

If this is a new topic for you, it's critical to understand some of the topics covered in this inground swimming pool construction video such as:

  • The key differences between sand and stone  
  • How installers need to select backfill material based on the soil condition 
  • That neither sand or stone are inherently "bad" backfill materials
  • The consequences of using sand backfill in the wrong conditions

It's also important to understand that this topic of backfill material is only one aspect of our complete fiberglass pool installation methodology called Rhino-Loc Construction which virtually eliminates all of the most common challenges associated with the inground swimming pool construction of fiberglass pools.  You can learn about the complete Rhino-Loc system here.
