Mr. LAMANNA Luigi Franco Mr. LAMANNA Luigi Franco has worked in these 45 years as a professional consultant and technical management activity in the various civil, industrial, military, hydraulic, railway, motorway sectors and in the last 25 years in the "Tunneling" sector for land consolidation. , their stabilization in excavation, etc. For the "Mining" sector, in recent years it has been dealing with the extraction of "Rare Earths" and for the stabilization of slopes [open pit mines], consolidation of the rock support, shotcrete, particular injections with cements or formulations resinous while, in the "Engineering" of particular "Technologies", for the rehabilitation of deteriorated reinforced concrete structures, following earthquakes or other causes, in particular concrete or earth dams. Particular attention is paid to the use of special and formulated "resinous" cements and related technologies for the consolidation and repair of masonry, iron and wood.

3. This PDF wants to be a sincere thanks to all those, around the world,
have been able to believe and value mine, and that of all those who
have been able to provide their collaboration, together with myself, in
the countless States or jurisdictions in which we have been here I'm.
Our work has always been aimed at "professional / company"
technicians interested in our "consultancy and / or supply activities" of
specific technical solutions.
the air, but to have materials, in particular a binder that has the same function as cement and
that is able to overcome resistance to aging, as well as mechanical, physical and chemical
resistances exceeding 100 years. The latest recent studies, the results of tests, confirm that we
can safely exceed 500 years.
The study of our blend, selected with inert details, also linked to a very stable formulation
based on synthetic resins, we have been able to ascertain that it is truly a special material of
the highest quality. In fact, from tests carried out, we have seen that it is able to pass rigorous
quality controls where the final result is a resistance from 4 to 8 times higher than that of
traditional concrete, with compressive strength values that can reach close to 3,000. kg /
cm2.
I take this opportunity to anticipate that in recent years the attention
of the undersigned is also directed towards the study, research and
development of new materials, not only to reduce CO2 emissions in

4. Mr. LAMANNA is still present on the market to answer
your ever increasing questions in the field of specific
technical consultancy, also in consideration of the
innovation and development in progress, to a
considerable number of complex projects in the field of
"Tunneling. "," Mining "and" Engineering ".
Our main objective is still to contribute to the quality of
the services offered, through the consolidation of
professional ethics in Italy and in the world, trying to
become a point of reference for "clients", "designers"
and "performers".
NOTE:
IN 2005, ABOUT 17 YEARS AGO, AS YOU CAN UNDERSTAND,
THROUGH THE PAGES OF AN ITALIAN SECTOR MAGAZINE,
ASKING SUBSCRIBERS AND NON-SUBSCRIBERS, I ASKED IF
THEY WERE KNOW HOW MANY TYPES OF EXCAVATION
MACHINES ARE USED FOR EXCAVATION. I HAVE NOT
RECEIVED THE ANSWER HOPED FOR.

5. The range of services offered also includes “project
consultancy” and “program management” activities.
If necessary, we are able to "train" professionals with whom
they will be able to work in synergy with locally selected
personnel, on civil engineering projects, in all public and private
sectors.
The "professionals" selected will be able to operate, according
to European and international standards, in full freedom and
autonomously evaluate the best solutions, proposed by us, for
the needs of each individual project, to satisfy your every need.

9. AN EXAMPLE OF PROBLEM :
Cavitation is a phenomenon that consists in the
formation of cavities that are filled with water vapor
within the flow, this occurs when there are negative
pressures equal to or lower than the vaporization
pressure of the fluid. These passing in areas of higher
pressure can implode and cause serious damage to the
concrete of underground hydraulic works (due to the
phenomenon of fatigue).
