What Is Rhino-Roc Construction? 

Learn How It Works And Why We Created It

Rhino-Roc is our unique installation methodology that virtually eliminates the sources of major fiberglass pool installation problems such as:

  • settlement or shifting of the pool shell
  • leaks in plumbing lines and around jets and pool other fittings
  • separation between the pool and patio
  • bulges in the side walls of the pool

How Does Rhino-Roc Work?

Rhino-Roc is a combination of innovations and best practices that we have developed to virtually eliminate the risk of fiberglass installation problems.  

The Components of Rhino-Roc Construction:

1.  Our “Rhino-Rod” That Fuses the Pool Shell and Patio Together

One area of concern is where the pool shell and patio join.  We developed our Rhino-Rod to serve as a means to fuse the pool shell and patio together to prevent shifting, settlement, or movement of any kind that could result in structural failure.  The Rhino-Rod is a twelve inch long composite rod that we install into the top of the pool shell that becomes encased in the concrete bond beam that is poured around the perimeter of the pool.  

2.  Plumbing Straps That Secure Plumbing To Pool Shell

One of the major causes of pool plumbing leaks is movement.  When pipes shift this sets in motion a chain reaction that puts undue stress on the pipe, plumbing connections, and the components of the pool the plumbing is attached to such as return jets, skimmers, drains, etc.  In Rhino-Roc Construction, we secure the plumbing by fastening the pipes to the pool shell using a strap system that insures there is no stress placed on any component of the plumbing system.

3.  All Schedule 40 PVC Hard Pipe

When installing a pool, there are basically two types of plumbing pipe to choose from: hard pipe or flexible pipe.  In Rhino-Roc Construction, only hard pipe is used.  Because it does not flex and bend with the contours of the pool, it does require more effort to install, but because flexible pipe is actually not rated for underground use we don’t feel it’s worth the risk.  To learn more on this topic simply Google: “Flexible PVC Pipe vs Rigid Pipe: Which Is Best?”

4.  Crushed/Chipped Stone Backfill Material

What is backfill material?  It is simply the material that we place under the pool and around the outside of the pool shell after it is set in the excavated hole. The use of clean, crushed stone backfill is imperative to the long term success of a fiberglass pool installation.  Sand, which is the traditional material used in the industry works well in areas with pure sandy soils, but it doesn’t take a soil specialist to understand what happens to sand when it becomes saturated with water: it liquifies. Consequently, our experience has been that there is a much higher percentage of fiberglass pool installation issues when using sand as a backfill material such as:

  • Settlement of the Pool Shell after installation
  • Leaks developing from pressure on plumbing as a result of sand settlement
  • Bulges in the side walls of the pool shell

These are challenges we faced and fixed early on, but they virtually went away overnight the moment we stopped using sand and began using clean, crushed stone as our backfill material.  It drains better, it doesn’t move, and doesn’t change it’s properties when wet.

Watch the following video, taken from our 2016 Dealer Conference, that discusses our experience using both backfill materials and when and how it is appropriate to use them:

6.  12” Thick Concrete Bond Beam Around Perimeter Of Pool

All inground fiberglass pools require some concrete to be poured around their perimeter to stabilize the pool shell.  With Rhino-Roc Construction, this concrete bond beam is poured extra thick and flows under the lip of the fiberglass pool shell and encases the Rhino-Rod.  As this concrete “bites” around the Rhino-Rod and the lip of the pool, it “locks” everything into place ensuring the pool and Learn about River Certified Dealers patio will be structurally secure for many, many years.    

 7.  Sump Pipe For Monitoring/Removing Ground Water

We can't show this in the diagram but eventually, all fiberglass pools will need to be drained.  There needs to be a means to inspect and remove any groundwater that is present around the outside of the pool shell to prevent damage from occurring.  Because we are thinking long term, our Rhino-Roc Construction includes a “sump pipe” that gives one the ability to do just that.

Rhino-Roc: The Story

The following video, taken from our 2016 Dealer Conference, describes our humble beginnings and how we came to develop Rhino-Roc Construction.

Did you know that before we partnered with Thursday Pools and began manufacturing our own pool shells, that River Pools actually started as an installation company?  That’s right, we have been fortunate to have installed well over 1,000 fiberglass pools over the years and we’ve always been motivated by three guiding principles.

To give our clients:

  • A great experience
  • Peace of mind
  • An installation that stands the test of time

Because of our efforts to continually innovate new and better installation practices and because of our desire to share what we’ve learned with the world, we have become recognized as thought leaders in the industry, especially with regards to fiberglass pool installations.  We have been listed as one of the Top 50 Pool Builders in America, we teach fiberglass pool installation classes at Industry Trade Shows on the National and Regional levels, and millions of folks just like you read and watch our fiberglass pool installation articles and videos on our website to deepen their understanding of the process.
