GeoStone gets its connection strength from a patented open core design that relies on what we call Rock Interlock.  In this process the open core of the GeoStone block is filled with a number 57 stone (or comparable) level with top of wall.

 

The next course is placed and filled.  The Rock Interlock is the friction provided by hundreds of rocks in a single core interlocking with each other and those in the course above and below it.  This happens in every block.  To put it in simpler terms, it is the same type of effect you get with Velcro, except this is obviously on a much larger and more powerful scale.

When you add that friction with the weight of the block and the rock, you get what is called block to block shear.  Block to block shear is the resistance of the filled blocks to move independently of one another.  This resistance is powerful enough to retain massive earth structures.

Rock Interlock has been professionally tested in various laboratories throughout the United States and results have shown it to be one of the most powerful forms of connection in the Segmental Retaining Wall (S.R.W.) industry.  Please feel free to address any questions you might have on this process by clicking on the following link.  CLICK HERE

GeoStone, in keeping with its standard of excellence is proud to announce its system of Absolute Positive Connection.  With this system the connection strength is now determined by the strength of the geogrid.  Also, you can view the Positive Connection movie!

We mix a polyester resin with sand and pour the catalyzed mixture into the open core of the module onto the exposed geogrid and rock.  The module is then filled with rock.  When the resin hardens it bonds rock and grid into an indestructible mass that will not allow the grid to pull out of the wall.

The polyester resin is totally compatible with the PVC coating on the geogrid. 

We apply this positive connection application at each geogrid level in the wall or as directed by the wall design.

The proof is in the numbers!

This Truly is Absolute Positive Connection!

Click on the icon above to view an adobe file that illustrates a little more about our process for positive connection in segmental retaining walls. Because of the way it permenantly locks the grid and courses above and below, we feel confident that this is one of the most powerful systems of connection on the market.

The Hardscape Handbook.pdf (3.30 MB)

Just a little four page document that sums up what we feel is some of the more important things you will need to know about retaining walls.  The Hardscape Handbook shows actual designs of structural walls as well as 3-D renderings of Stairs and radii.  There is also a step by step process of how to build both a residential non-load bearing wall as well as a commercial load bearing wall.  We encourage you to click the link above to download and view before taking on your retaining wall project.
