The IBIX System for Cultural Heritage and Modern Architecture Conservation and
Planned Maintenance:
Innovative Solutions for « in situ » Diagnostics
and Conservative Media Cleaning
THE IBIX System for CH Conservation www.ibix.it – www.ibixmobilelab.it
IBIX S.r.l. was founded in 2000, IBIX is Member of Assorestauro, Italian Association for Art, Architecture and Urban Restoration and is actively involved in the Association’s activities to promote the Italian Phylosophy related to CH Conservation.
IBIX S.r.l. has played the lead in two important conservative restoration projects promoted by the Italian Gorvernment, i.e. the Restoration of Peter I’s Gate in St. Petersburg (Russia) and the Conservation of the Clock Tower at the Ottoman Imperial Dolmahbaçe Palace in Istanbul.
IBIX main goal: to supply a comprehensive solution to the needs of CH conservation
“Surface cleaning of historic and modern architecture is the
most delicate part of the entire conservation project.
IBIX Company Commitment:
IBIX is committed to promote a conscious approach to the
Conservation of Cultural Heritage
IBIX FOR THE CONSERVATION WORLD
Our main objective is to propose cleaning solutions and
integrated methods that can best suit the needs of each
conservation intervention and fully respect the indications
of the conservation project and of the Cultural Heritage
protection authorities.
Cleaning: from the point of view of conservation the purpose of cleaning
is the removal of anything that is harmful for the stone:
Soluble salts, soot and scales that are insufficiently soluble or insoluble, layers of
different materials deliberately applied that are not suitable or no longer functional,
invasive vegetation, animal faeces etc, and it must respect:
Polychromies and natural patinas,
but also the most superficial layer of the stone…
The selection of the method to be used must centre on the nature of the
substances to be removed, on the type of surface to be cleaned (level or
in relief, more or less damaged), and on the extention of such surface.
Therefore, on a single monument, several methods may be used
depending on the needs.
However, the selection must favour those methods that can be
controlled by the operator and stoped when deemed
appropriate…

IBIX philosophy:

To make a comparison with medicine:
From the Shaman… (“radical” interventionism)
…to the “conscious” intervention (scientific method)
…to preventive medicine! What is the difference?
SCIENTIFIC APPROACH and
ANALYTICAL TECHNIQUES!
On-site tests on products and technologies
Quality control of the intervention
Therefore, SPECIFIC CLEANING METHODS
(every historical building is unique, it is impossible
to standardize the process)
Analysis of materials and degradation
Programmed maintenance
Surface cleaning of historic and modern architecture: the most delicate part of the
entire conservation project
The IBIX® method provides an important contribution to the cleaning cycle because it reduces chemical and mechanical surface stress to a minimum.
We can achieve optimum calibration of the cleaning process by adjusting both the operating pressure and the grain size and hardness of the media.
Starting from the 1990s (the days of “old Jos”) there has been the introduction and general acceptance by Cultural Heritage authorities of methods that exploit an air vortex to achieve tangential impact of the
media on surfaces, reducing the potential for damage from direct impact.

Thanks to its constant research and development in co-operation with conservation experts and
professionals, IBIX has developed an innovative cleaning method, based on a scientific approach to the problem and on easy-to-use, versatile and eco-
sustanable technologies
THE COMMITMENT OF IBIX TO RESTORATION Research for the development of cleaning
methods
IBIX’s research led to the development of HELIX®, the new IBIX system that
implements a rotational flow of the air and media mixture, this ensures top performance
in terms of delicacy of intervention and productivity.
The Patented HELIX® SYSTEM new operating gun equipped with an original helical vortex nozzle design
maximum protection of the valuable surface patinas and historic coatings of precious artefacts
optimum worksite performance save in all cases the need for careful training of operators
The extremely low pressures under which the equipment can operate (down to 0.2 bar: the equivalent of a whisper) and the delicacy of the jet (thanks to the helical vortex) today make HELIX® the most suitable system for intervention on surfaces of artistic and architectural prestige, the HELIX system preserves the surface patina with no risk of uncontrolled abrasion of the surfaces.
CH operators are able to rely on IBIX® systems for any media cleaning procedure;
the new HELIX® system provides a winning
solution for all those interventions where helical air-vortex media cleaning systems are
specified to ensure total delicacy and respect of historical surfaces
THE COMMITMENT OF IBIX TO RESTORATION Research for the development of cleaning
methods
IBIX Mobile Lab® ST01 is a comprehensive & versatile portable laboratory to analyse and diagnose historic building materials in an easy and clear manner. By using this equipment the basic techniques to categorise natural and artificial stones as well as degradation phenomena are made available to all those working in cultural heritage preservation.
THE COMMITMENT OF IBIX TO RESTORATION Research for the development of cleaning methods
IBIX Mobile Lab® is a must to efficiently manage cultural heritage throughout the entire conservation process, from the fact-finding project to the conservation itself, paying special attention to programmed maintenance.
THE COMMITMENT OF IBIX TO RESTORATION Research for the development of cleaning methods
The methods of analysis used comply with both Italian and European regulations by UNI-Beni Culturali (Cultural Heritage) and EN-Conservation of Cultural Property respectively. The equipment features a multilingual user interface.
The dedicated software developed by START Apps S.r.l. controls all operations. It also guides the operator, step by step, on how to carry out chemical-physical tests in order to obtain objective results.

The ‘PRINT REPORT’ function included in the software that manages the IBIX Mobile LAB is used to create a comprehensive technical report of tests in PDF format, with a simple click of the mouse! The report shows charts and graphs with the results of the analyses carried out per sample; it includes the reference regulations and standards, test conditions, images to locate the collection points, and a guide to understand the readings. The comparisons set among the different measurements are arranged by the software following a graphic format that facilitates reading and interpreting data.
20
These results will help designers, restorers and administrators of cultural heritage to devise a modern
approach to conservation.
Diagnosis projects are easily managed via simply structured and intuitive software, with illustrative
images of the test steps and procedures and a flexible site-related data management system.

IBIX® Media Cleaning Systems
WHY is the HELIX® System by IBIX specified by architects,
recommended by CH conservators and adopted by restoration
companies ?
Because the HELIX portable low pressure media cleaning system
preserves the surface patinas with no risk of uncontrolled abrasion of
the surfaces and is
. easy to use (plug & play system) + maximum confort for the operator
. lightweight and manageable
. energy-saving :requires small low fuel consumption air compressors
. green (low media and water usage)
. keeps worksite costs low
. ensures optimum worksite performance
