¿WHY TECNAN? SPECIAL CHARACTERISTICS

TECNAN EVOLUTION IN CONSTRUCTION SECTOR:

RESTORATION AND CONSERVATION OF HISTORIC HERITAGE

BUILDINGS

•In this sector, TECNAN has verified the potential of its products as new systems which does not change the aesthetic of heritage buildings at the same time that they protect the surfaces against climatic agents

and against human aggression.

EMBLEMATIC CONSTRUCTION

•The achieved successful cases are transferred to constructions such as museums, medical centres, theatres

and modern architecture.

REHABILITATION, REFORMS, CLEANING AND MAINTENANCE; EXPANSION TO TRADITIONAL

CONSTRUCTION SECTOR, NEW CONSTRUCTION, RESIDENT

COMMUNITY.

•Requests from remodelling and industrial sector lead us to

develop an anti-stain solution for all porous substrates.

replacement, and final protection of highly outdoors exposed elements with inert

water repellent product, colorless and breathable according to tests over stones

and mortar elements…”

Successful applications – Heritage Buildings

(Text extracted from the petrological tests carried out by GEA Geological

Consulting):

"From the results obtained, it can be concluded that the most suitable protective

treatment for the limestone of the cathedral of Burgo de Osma is Tecnadis

PRS, due to its high contact angle, its slight modification of the original color of the

stone and its low reduction of water vapor permeability “

“ALMUDENA CATHEDRAL OF MADRID: Rehabilitation of the Crypt” 2013

Architectural and ornamental restoration of the Crypt of Nuestra Señora de

La Almudena Cathedral in Madrid:

The intervention recovered all vaulted elements, bases, columns, stone capitals

and, granite and marble floors.

“Cleaning of the Crypt access of Almudena Cathedral. Hydrophobic protection

of the exterior surfaces by water repellent treatment based on ceramic

nanoparticles.”

Project: May 2013. Proyecto: Mayo 2013. Ministry of Education, Culture and Sport. Government of Principality of Asturias.

(Project extract) [...] Removal of black crusts accumulated over more than seventy years by

innocuous technologies, tacking into account the specific parameters of the application

previously established by petrologists: neutral solvent (white spirit) applied with hyssop after

softening the wax surface by hot air gun over marble pieces of the pre-romanesque

architecture; projection of dry air with pumice stone microparticles over the most neutral

stone surfaces, and laser beam over the most strong surfaces. Subsequently, the

disintegrated fillers behind the pedestals were reduced in order to define its Lastra dolomite

ashlars, afterwards, lost patinas were completed and final protective treatment was

applied, water repellent with ceramic oxide nanoparticles dispersed on acetone was

used. It is a treatment that allows the breathability of the stones without change the

aesthetic of the substrate, the brightness and texture and without modify its tone and colour.

These interventions preserved both the historical graffities of the pilgrims and observed

polychromies.

Next intervention 2017:

Restoration and protection of the cloisters of the Oviedo Cathedral with

Aquashield Ultimate superhydrophobic product.

BEFORE AFTER BEFORE AFTER

“SEVILLE CATHEDRAL: Restoration of cover and outdoor elements Since 2015 until now

“…“ Central dome of Seville cathedral repair was involved in dismantling, recovery and

cleaning of existing mud brick pavement in order to use them in after works,

recuperation of intermediate fillers and following new pavement was performed with

the cleaned bricks of the dismantling works. Finally, hydrophobic protection and

water absorption reduction treatment from TECNAN was applied.

…[..] Mechanical cleaning and elimination of crusts and patinas created due to water

runoff on tube line areas, rain gutter, buttresses and selected areas which were highly

degraded. Subsequently, water repellent treatment.

“RESTORATION WORKS OF THE FRONTIS FACADE OF SANTANDER CATHEDRAL CRYPT” 2016

“… Façade of limestone of different qualities and ages due to the rebuilt of the

cathedral in different times. It is a façade that despite of being orientated to east is

located in the most dark area of the cathedral, being part of the crypt that is under this

emblematic building.

The treatment performed over all the elements has been:

1.- Cleaning of the facade by the application of cold pressure water on the surface for

the elimination of detritus.

2.- Removal of rusted metallic elements anchored to the stones, which are not working.

3.- Breaking by manual means of damaged, loose and with risk of detachment mortars

and plasters.

4.- Performance of mortar joints, in order to imitate the original stone masonry, applying

cement mortar, lime, additives and selected aggregates, permeable to water vapor.

5.- Application of innovative hydrophobic treatment protector based on

nanoparticles, TECNADIS PRS PERFORMANCE, treated by mechanical means

(electric turbine).

Successful applications – Modern ArchitectureBOTÍN CENTRE COMPLEX AND TUNNEL (SANTANDER-SPAIN) 2014

Application of nano-protection with hydrophobic and oleophobic properties, Tecnadis

PRS Performance on the facades of the Botin Centre Building and on the white concrete

prefabricates of the tunnel. Reduction of cleaning time and recourses of the prefabricated

pieces that were usually turned dark due to the automotive contamination. Before the application

of this treatment, the cleaning was made with abrasives chemical products, nowadays they are

cleaning only with pressured water.

Renzo Pianno Project:

The Centro Botín is a new space for art, culture and the diverse activities of the Fundación

Botín. It will be constructed in the Jardines de Pereda, on the seafront of the city of Santander in

north-western Spain. The project reclaims an area currently used as a car park, restoring it to the

city. The site, organized as an extension of the city grid through the existing park, will provide

direct access from the historic town centre to the sea and will enhance visual connections with

the water.

The exterior will be clad with small off-white ceramic tiles that easily adapt to the shape of the

building and that also have a shimmering, mother-of-pearl finish, which strengthens the

building's luminosity, under Santander’s often grey sky.

Successful applications – Modern ArchitectureART, ARCHITECTURE AND TECHNOLOGY MUSEUM (LISBOA-PORTUGAL) 2016

The building for the Museum of Art, Architecture and Technology was designed by

British architecture studio Amanda Levete Architects (AL_A).

Boasting over seven thousand square metres of new public space, AL_A’s

building makes use of the area’s natural features, incorporating an architectural

narrative that is in keeping with both the cultural heritage and future of the city.

The vast south facade is the building’s most iconic feature and it works as a large

reflector interacting with the light coming from the river. The angle and position of

the tiles were planned in order to create specific luminous effects according to the

time of the day and year.

Application of hydrophobic and oleophobic solution on more than 18.000

ceramic tiles of this emblematic building. This treatment was carried out in the

ceramic plant of Ceramica Cumella Factory before the installation of the tiles on

the own building. The tiles are treated with a microcrack enamel that were darken

due to pollution and dirt. Thanks to the application of this nanotechnological

treatment the white colour of this building remains its aesthetic for long time.

HYDROPHILIC PROPERTY ANTI-DUST PROPERTY

This treatment for glass surfaces is an innovative superhydrophilic and anti-dust solution based on nanotechnology that provides self-cleaning

properties. The superhydrophilic property allows water to contact the surface creating a thin layer which dries homogeneously, avoiding the

appearance of water marks, and reducing dust adhesion.

Not treated Treated

This treatment for metallic surfaces has the properties to protect the treated surfaces against

corrosion. In this case, half of cast iron lamppost was treated and all the piece was submitted

to accelerated humidity test on a humidifier camera for 1h and 35 minutes.

As you can see in the picture after this test the not treated area is totally rusted, whereas, the

treated area with Tecnadis Metalcoat keeps its aesthetic and properties.
