On the afternoon of the tornado with teh sirens blaring, the homeowner turned on the television. Broadcasting on the TV was live footage of the tornado touching down about 3-5 miles away from his home. He immediately took shelter in his ICF safe room inside of his ICF house, and waited for about 5-10 minutes before it was apparent the roar of the tornado was directly on top of him. He could hear the noise and the sound of the roof getting sucked up. After agonizing minutes he came out and witnessed the destruction to his home and his neighborhood. As you will see from the pics below, the south side of his home took the brunt of the winds, and the tornado even threw a Toyota Tundra directly into the exterior wall of the safe room, and yet the wall did not budge.

Project Profile

Kenny had his home built back in 2001 by Bill R. and they used the waffle grid eForm for all of the exterior walls and for an above ground safe room. The waffle grid ICF is now about obsolete for all practical purposes, as all of our products and the majority of the ICF industry’s are flat wall ICFs.

Kenny has said the ICF walls without a doubt saved his life. He is planned on stripping out the home and keeping the ICF walls standing and rebuilding the rest.

Some other general notes on Kenny’s home in Newcastle, OK. Overall all of the ICF walls seemed to be structurally fine and the damage was to the missile hitting and chipping away the foam after the brick blew off.
