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

testing lab
Risk Category III: Buildings & Structures 185 mph

The Miami Dade wind load test is the most onerous 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:

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.

Test 1

Initially we created a mechanically   adhered ventilated backdrop rainscreen curtain wall using the Gridworx Ultra cladding system and four Dekton panels.  These panels measured 126” x 56” each delivering a wall measuring over 9’ x 21’.


Next we attached this  wall assembly to the wind and vacuum chambers of  the testing facility.

Test 2 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 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 until it was finally shut down. The engineer then announced they had exceeded the testing requirements.

They took this test to 187 mph and could not break the Dekton with Gridworx system.
