COMPARISON OF ENGINEERED MODULES ON THE MARKET
All engineered modules in the market have been granted a patent based upon their unique method of connection. Connection methods include lips, pins, lugs, bars, clips, and open core.
All engineered modules have been tested in NCMA approved testing labs to determine the precise strength of their connection. Their connection strengths differ.
Engineers use the connection strength numbers achieved by the test results for each module to design walls with that module.

These charts show GeoStone's grid pull out tests in comparison to other systems' test results using various grids. GeoStone's open core is shown in comparison to a commercial lip system and a commercial pin system.
Each chart represents a different grid strength or gauge. Wall height is represented as well as pressures exerted in the effort to simulate the force required to represent grid pull out or wall failure. The ultimate goal of these tests is to see how much force is required to produce a simulated wall failure.
The black line represents the GeoStone Retaining Wall System. The chart shows in all cases that due to its larger open core and Rock Interlock, the GeoStone system continues to get stronger as the wall gets taller resulting in far superior connection strength. In other words, the grids do not pull out of the GeoStone wall.

Wall will abut concrete wall, turn inside 90° and continue along face of concrete wall as veneer
Wall will abut concrete wall, turn inside 90° and continue along face of concrete wall as veneer - Back notch on block
Back notch on GeoStone block shown above in the middle allows block to be "clipped" to another structure without affecting how the next course sits.
Back indention on GeoStone block allows block to be "clipped" CMU's adding a tail to the GeoStone block for gravity wall applications. This moves the unit's center of gravity back and increases unit weight. Can be used in top courses as additional resistance to overturning.

Property code restrictions prevented the use of batter in some places due to sidewalk widths and parking areas. Toe of slope was variable as top of wall location was fixed.
Rock Quarry walls - 47' tall - Max loading. Rock crusher located below mandated minimal batter in wall or near vertical (1°) as settling over time would lead to true vert.
