Large Blocks Walls come in many different sizes, but on average they weight about 1 ton per block. Compare this to the smaller blocks that average between 20 to 120 lbs. Due to their massive size, large blocks do not utilize geo-grid until much taller heights.
In general the design specifications for large blocks walls suggest maximum installation heights under certain assumed conditions. These wall heights get calculated using assumed material properties and loading conditions and will vary from location to location depending on the soil properties and terrain. Since soil conditions and topography vary greatly from site to site GEOTILL has the capacity to perform engineering analysis for each wall installation.
