Miami Dade Wind Load Test Blown Away By
Dekton With the Gridworx Ultra Stone Cladding System

The Miami Dade wind load test is the most onerousTesting Lab wind test in the United States. The law creating the Florida Building Code was enacted by the Florida Legislature and became effective on March 1, 2002. This law defined High-Velocity Hurricane Zones (HVHZ) and is specifically related to Miami-Dade and Broward Counties. Our system was subjected to the following test:

  Risk Category III: Buildings & Structures 185 mph
Dekton partnered with Gridworx for this testing leading to certification for Miami-Dade County building approvals. The purpose was to demonstrate our products meet the unique requirements for a hurricane prone area. When severe weather strikes, this approval certifies the performance of our products may very well contribute to saving lives. It is this level of testing and proven performance that demonstrates the standard for quality and safety with the fusion of Dekton with Gridworx.

Next, we attached this wall assembly to the wind and vacuum chambers of the testing facility. First was the positive wind load test. This was followed by the negative wind load test. In a real-life incident, negative wind load is generally a 20% greater force than positive wind load. Negative wind load is created when the wind blows across the face of the building literally sucking the cladding from the structure. This force is exacerbated at the corners of the building as described in the Bernoulli principle.

The wind turbine began accelerating at a faster and faster rate. As the noise started to become unbearable the test was suddenly shut down. The chief engineer then announced the cladding system had exceeded the testing requirements.

He further exclaimed They took this test to 187 mph and could not break the combination of Dekton / Gridworx.

Store frontMany times the end justifies the means.  Take note of the latest Dekton / Gridworx masterpiece.

Anyone familiar with Miami will recognize 100 Biscayne Blvd. as being on the waterfront.  This is truly the epitome of a High-Velocity Hurricane Zone (HVHZ).   

Those who might find themselves in this area during a hurricane will be comforted with the knowledge that Dekton with Gridworx will be able to withstand these forces of nature.
