Proven and tested seismic safety.
Anti-seismic characteristics of wood cement blocks and panels



Isotex wood cement bearing blocks and slabs in Isotex allow the construction of extremely safe anti-seismic structures. The formwork blocks are dry-laid, filled with concrete, in which a horizontal and vertical reinforcement is inserted that connects the foundation to the edges of the floors, ensuring a solid load-bearing reinforced structure.
Thanks to its excellent structural characteristics, the Isotex building system is used in highly seismic areas of first and second category.
The Isotex building system is anti-seismic.
Lots of earthquakes, no damage
Italy is an area at high seismic risk due to its positioning between the African and Euro-Asian tectonic plates. Periodic earthquakes have caused, throughout history, with multiple damage and victims. Since Isotex began to build in Italy with its wood cement blocks and floors , several major earthquakes have occurred.
Following these seismic events, many of our customers have testified to the resistance and anti-seismic resilience of our building systems. Eco-sustainable and anti-seismic buildings and houses, built with the Isotex system, have withstood these seismic events without suffering any damage, not even a crack.
Testimonials from our customers

Costruzioni Boccanera lvo e Fratelli snc is very pleased with the product, especially for its earthquake resistance.
Ing. Boccanera Ivo - 03/03/2017

My house made entirely of Isotex blocks did not suffer any damage as a result of the 6.5 magnitude earthquake that occurred a few days ago. I am very satisfied with the product, both for its seismic and thermal resistance.
Alberto Rastelli - 09/11/2016

The two buildings did not suffer damage, demonstrating the effectiveness and anti-seismicity of the construction system. Several buildings in our municipality, built with different systems, were evacuated and declared unusable.
Il Melograno II s.r.l. - 13 may 2009

I have lived in Teramo in an Isotex building since 2010. With all the earthquakes that have occurred since August 2016, there has been no damage. I cannot recommend this material highly enough.
Tito di Bartolomeo - 06/02/2017

I decided to build with ISOTEX blocks and after the shocks that have hit us in recent months and especially in January 2017 I can say that the choice was more than ever right!
Simone Mastropietro - 05/02/2017

The building built with Isotex formwork blocks did not suffer any damage or visible damage, unlike other buildings that were hit by the earthquake and reported significant damage.
Marcon Enzo e Dante construction company s.n.c. - Chiusaforte 4 JUNE 2007

The buildings made of Isotex blocks, following the earthquake in Bovec (Slovenia), did not show any damage and are intact in all their parts, unlike many other buildings which showed obvious damage and injuries
Construction company - PIZZINI A. & SPECOGNA - 5 june 2007

The buildings constructed suffered the earthquake in Amaro (Italy) recorded on 14/02/2002 with a magnitude of 4.9 degrees on the Richter scale. These buildings were all only about 24 km from the epicentre of the earthquake.
Geom. Daffara,legal representative of the Daffara Costruzioni company - 8 JUNE 2007

Following two earthquakes of magnitude 5.6 and 5.1, the buildings made with Isotex formwork blocks did not suffer any type of damage and still show their integrity.
CO.GE.P di Paschini geom. Renato - Tolmezzo - 4 june 2007

We decided to change the construction system and adopted the ISOTEX system. To date we have carried out about ten interventions and we can say that the characteristics are exceptional, in terms of seismic, thermal, acoustic, etc...
Lino Costantini - LC Immobiliare - 7 june 2018

We are experiencing difficult times, but I wanted to let you know that I have just finished building the house with your material that fortunately withstood the great shocks of the past few days without any problem. I wanted to let you know how satisfied we are with Isotex.
Luca Goldoni - 18 june 2012

We immediately perceived the benefits that this construction system brought us in terms of thermal and acoustic insulation, as well as the awareness of living in a building with great anti-seismic capabilities that gives us safety every day. Davide Rossi - 18 june 2018

References to Italian anti-seismic regulations
On August 8, 2011, the Higher Council of Public Works published the reference guidelines for designers, technicians in the sector and competent Control Bodies.
Pursuant to chapter 12 of the Technical Standards, the Guidelines provide theoretical and experimental references and design and construction indications for the design and calculation of buildings made with load-bearing panel building systems based on the use of formwork blocks and weakly reinforced concrete cast on site.
The building system must be characterised from a structural point of view through an adequate number of experimental tests, according to the Technical Standards in force, to demonstrate an effective behaviour of the load-bearing elements with respect to vertical and horizontal actions, including cyclical.


Technical documentation required by the LLGG
The following documentation must be prepared and made available by the Manufacturer:
- Technical data sheets of the blocks
- Construction details
- Example of structural calculation
- Certificate of experimental evidence
- Operating manual for assembly
Isotex technical documentation at your disposal.
Anti-seismic design and construction
Operative assembly manual
This catalogue explains the correct method of laying blocks and floors in wood cement, with the help of construction details and tips on how to properly unload and lay Isotex products.
Isotex wall verification software
Isotex provides structure designers with free software for the verification of Isotex walls. Isotex engineers are at your disposal for any clarification.
Interpretive report and
experimental testing
With the new NTC2018, a technical testing campaign was carried out on the Isotex walls, at the Eucentre experimental testing laboratory in Pavia, obtaining excellent results in terms of anti-seismic resistance. Within the Report you will also find Guidelines, beam-wall tests, behaviour factor q0=3 and Isotex exoskeleton study.
Structural calculation examples
Isotex provides examples of calculation representative of the structural type with reference for modelling and verification for the correct installation of floors and load-bearing walls with Isotex wood cement formwork blocks.
Isotex block data sheets
Isotex provides technical sheets for each type of product where system characteristics, mechanical characteristics and for the modelling/verification of structural elements are included.
Construction Details
The construction details provided are described in specific illustrative sheets that must contain indications relating to different technical aspects of the product, such as the positioning of the reinforcements.
