The cement-bonded wood fibre blocks are laid dry, thereby eliminating the various drawbacks of mortar, and subsequently filled with concrete to create a high load bearing structure. These structural characteristics allow use in first and second category seismic areas.
Italy is positioned at the overlap of African and euro-Asian tectonic plates and thus is at high seismic risk. Periodic earthquakes in Italy over the course of history have caused immense damage and innumerable casualties.
Since Isotex began to build in Italy with structural and cement-bonded wood fibre blocks several major earthquakes have occurred.
Following these events, many of our customers have testified to the quality and excellent performance of our construction systems during earthquakes. Houses built with Isotex have withstood these earthquakes without damage.

ISOTEX has always given absolute priority to the static aspect of the walls and floors made from their products.
Already in 1994 ISOTEX had begun a major collaboration with the University of Bologna to test different Isotex load-bearing walls in the laboratory. Then in 2000, a simulation of an earthquake was carried out with the use of a vibrodyne on a building made entirely of Isotex walls and flooring. Both tests gave optimal results.
With the entry into force of new seismic building codes further experiments were carried out on Isotex walls and structures at the renowned Eucentre laboratory, again obtaining excellent results in terms of earthquake resistance.
Of the more than 80,000 homes built with Isotex products in Italy since 1984, a significant number have endured earthquakes of great intensity, up to 6 on the Richter scale. These buildings suffered absolutely no damage, not even tiny crack.
On 8th August 2011 guidelines were published on the website of the Supreme Council of Public Works as a framework for planners, technicians and competent authorities.
MINISTERIAL GUIDELINES
In accordance with Chapter 12 of the Technical Regulations, these Guidelines are intended to provide planners, technicians and competent authorities with theoretical and experimental references and indications for planning and construction in the design and calculation of buildings constructed with load-bearing panel systems based on the use of moulded blocks and lightly reinforced with cast concrete on site.
EXPERIMENTAL CHARACTERIZATION
The constructive system must undergo, from a structural point of view, experimental tests of adequate number, according to the Technical Standards in force, in order to demonstrate effective behaviour of load-bearing elements faced with vertical, horizontal and also cyclic stress.
