Hi Carl,

The EVG 3D system has been tested for earthquake resistance and found effective up to a Richter 10 event. I have a university of Peru video clip showing seismic tests of 1.4G and the dramatic failure of steel reinforced cinder block yet the EVG 3D wire panel structure passes the test with flying colors. Engineering, structural and seismic studies are available. If you have actual studies that disprove or contradict the EVG information please forward it so I can review it.

Thanks for your input, Carl. Stay in touch.

Hi Summer,

You've brought up some excellent points. Let me assure you that positive answers exist for each of your concerns. However please understand that it is not my intent to sell you on using this system on this blog. I want you to be aware that I will be using it to build my own home here in Ecuador because I can see the distinct advantages it offers: resistance to earth quakes up to a Richter 10, speed of construction, resistance to insects and moisture and lower costs. As a Mechanical Engineer and experienced US home builder, this is the only construction method I will use in Ecuador.

Here are some additional web sites for you to explore:

Summer, please continue your due diligence and keep your questions coming. Thanks.

Thank you for the website for the construction company, Mobusa. I am studying it at this time, but without any post & beam added I cannot see how this construction made of basically, "Bull-Wire" that we use here for strong fencing can stand up to an earthquake over 4 point. I've attempted to go to their technical page, but it appears to be out of order at this time. It also appears there are no footings pored instead the slab is pumped directly onto the plastic covered ground area that is marked off by the framing material holding the concrete in place. Without footings, if this is the case, what holds the weight?

I have used this wire a few times and find it quite flexible in long panels as shown in the web video. I also find it easy to cut which makes me again question it's strength. Seeing the photos I believe it is the exact same wire size that I have used here. So again I can only question how this material/system can possibly be earthquake safe. Are there engineered research available and in field lab tests showing it's strength in all directions, especially with a heavy roof attached. What will keep it from swaying to the point of collapse? What is it's upward push strength?

Do you know anyone in Ecuador that is building post & beam with strawbale inset? To my knowledge this is one of the best earthquake structures available at a reasonable cost. I will continue to attempt to learn more about the Mobusa system once their tech page is up and working again.

My thanks,
Summer
