RAMMED AND RAW EARTH:features

Humidity regulator: absorbing important quantities of moisture and releasing them into the environment gradually. Maintains relative humidity in optimal conditions for humans between 50% and 70%.
Antistatic: does not charge electrostatically
It reduces dust formation and contributes to the prevention of diseases of the respiratory tract, such as asthma, and allergies.
It does not emit toxic gases, nor fumes and chemical reactions.
It does not emit radiation: it helps to protect against electromagnetic fields.
Protects from electrosmog: According to a study by Professor Schneider, of the military institute in Munich, 2.5 cm of clay plaster eliminates 75% of the radiation developed by a high voltage plant.
It is non-toxic and is used for its healing, cosmetic and antiseptic properties.
Thermoregulator: keeps the temperature cool in summer and accumulates heat in winter, facilitating energy efficiency.
Fire resistance: in addition to being fireproof, it also makes fibrous materials of natural origin such that it is often coupled and mixed.
Recyclable: 100%, the material can be recovered and reworked.
Do not waste water: for processing, the only water used is that of the dough and is completely returned to the environment during drying and maturation.
Low CO2 emissions: with the same number of units produced, the raw sector is able to consume up to 60% less energy than that of cotto, without emitting significant CO2 emissions into the atmosphere.
Sound-absorbing: the clay plaster has a good acoustic behavior, it attenuates the low-frequency sounds thus improving the living comfort.
It retains the smells: the clay, being a colloid, has a great ability to retain dust, gas and odors present in the air thus maintaining the healthy environment.
Breathability: alloy aesthetic effect and functional appearance.

DIFFERENT KIND OR RAW CLAY EARTH

There are many types of products from dry Raw Earth elements, to complementary and accessory, we report below those that we use most in the jobs that involve us.

WALLS RAW EARTH

CLAY PLASTERS

TERRAGENA SPATTER DASH Clay primer Terragena clay primer is made of selected clay and sand with a granulometric curve. TERRAGENA SB2 thanks to its thermal inertia and its great resistance to high temperature, it is considered the best plaster to be applied on wall heating panels, previously covered with a jute net. TERRAGENA SB8, which contains also pumice and perlite, is suggested to be used for thermal insulation. Application between 3 and 7 cm thick as a traditional thermal plaster. TERRAGENA FINISHING COAT clay finishing coat Different colours You find in the palette are made exclusively with coloured clays and natural aggregate, without using any colouring oxide or vegetable substances, that may compromise clay”s salubrity and features. To the most exigent public Terragena offers a particular finishing coat, added with very little peaches of selected spices mixtures that give the room a nice perfume. TERRAGENA SB3 clay smooth finishing TERRAGENA SB4 dry finishing coat made of fine aggregate and clay. TERRAGENA B4 PLUS paste finishing coat made of fine aggregate, clay and lime putty.

RAW CLAY COATS
On clay plasters, we suggest to apply Terragena Terrapaint in order to reinforce surface resistance. This product cab be applied directly on Terragena clay plasters. Should it be used on different surfaces please be sure that they are clean, solid, absorbent, dry, without greases, dyes and penetrating components. The product can be applied with brush, roller or spray machine. Two layers of paint applied with a break of 3-4 hours assures a perfect covering.

TERRAGENA FIX
This is a transparent solution of water and silicates, which consolidates raw clay plasters without blocking its transpiration. It is used before paint to consolidate old chalking lime plasters, or over raw clay plasters like Terragena SB4 and SB3 to prevent excessive chalking. The product should be diluted with 50% clean water before being applied. To improve its consolidating power we suggest to apply two or three hands at a distance of 5 minutes with brush or spray using a proper pump.

TERRAGENA WAX FOR PLASTER
This is an aqueous emulsion of natural beeswax to be applied over lime or clay plaster to avoid water absorption without stopping transpiration. Its use is recommended on external plasters to increase the washout. To be applied on dry surfaces through brush or spray and to be restored every 3-5 years on external walls. It looks like a white liquid, but it becomes transparent and semi-gloss when dry. This emulsion doesn’t release in the environment chemical or toxic substances for humans. Terragena wax for plaster is available in buckets of 14 litres, average consumption 0,10/0,20 lt/sqm.

FLOORS RAW EARTH

CLAY FLOORS
Clay floors are made of silica sand, calcareous sand with granulometric curve and selected clays. It is a good pavement for all kind of rooms, it is trampling resistant, it doesn’t produce dust and it is perfect to be put on heated floor or to detain heat in passive solar system. This floor consist of a base screed TERRAGENA P2 of a variable thickness of about 4 – 8 cm and it is a perfect base for wood floating floor. For the finishing we suggest to apply TERRAGENA P3 (clay finishing) and when it is completely dry the use of TERRAGENA OIL is the best thing to put on it. In order to obtain a more prestigious aesthetic effect the floor can be smoothed with a proper sander.

RAW CLAY FLOORS: P2PLUS
This screed is made of clay and selected sand of medium grain that has been stabilized with a particular natural and certified anhydrous sulphate. Components are raw materials of excellent quality, free of noxious substances or industrial products. P2PLUS is a good material for the realization of interiors screeds in green building. Thanks to its high thermal conductivity it is particularly suitable to be used on radiant floors. Thanks to the unique chemical reaction with water molecules it tends to reach a much lower residual moisture content than other cooked binders such as lime, gypsum and cement. Therefore it is an excellent support for the application of Terragena P3. Terragena P2PLUS shall be mixed with water for several minutes until it becomes a mixture like damp earth. It shall be applied and levelled like a normal screed made of sand and cement. It doesn’t require any reinforcement net or plasticizer, as it has very particular features. Processing times vary from 60 to 90 minutes depending on the weather, while liveability can be reached only after 2 or 3 days. The product should not be applied when temperatures are inferior to 5 ° C and its application on floor subject to damp rising is not recommended. If necessary we suggest to use an appropriate vapour barrier.

RAW CLAY FLOORS
All Terragena products are made of natural materials and do not contain any kind of oxide, chemical substances or synthetic resins. TERRAGENA P2 clay screed TERRAGENA P2PLUS stabilized clay screed TERRAGENA P3 clay finishing for screed

TERRAGENA FIXATIVES TERRAGENA OIL
It is used as a fixative in the clay in plasters and floors, to prevent chalking, increase mechanical resistance and make the surface waterproof. It is a blend of natural oils that does not release chemical or toxic substances for humans.

WAX FOR FLOORS
This is an aqueous emulsion of natural beeswax to be applied on floors to make the surface smoother and protected without stopping transpiration. In the box it looks like a white liquid, but when applied it dries in a few hours and leave the surface semi-gloss. This emulsion doesn’t release in the environment chemical or toxic substances for humans.

ACCESSORIES

JUTE NET
A natural net for plaster reinforcement. It is used as stitch within the plaster to avoids cracks caused by structural movement. Its use is essential for plastering on walls with different kind of struts or over panels.

REEDS FOR PLASTER
excellent support for lime- and clay plasters. The reeds, coming from Italy are bound one to one with a steel thread. It is essential on smooth surfaces, timber walls or in the construction of false- walls and ceilings. Terragena reeds for plaster

The attention to detail that distinguishes my projects, is born from a passion for essential topics related to the materials and ancient current technology, with a focus on environmental sustainability and a fairly strong interest in the energy saving aspects of the recovery , bio-architecture and its selection of natural materials, recycled, keeping in mind also the no less important aspect of the aesthetic component.

I love the supervision of the building sites and create personally rammed earth works. I love Artistic manual handcraft related to rammed earth, tadelakt, wood and materials in general.

Amo la cura dei dettagli, le tecniche antiche e attuali, la sostenibilità, il recupero, la bioarchitettura, i materiali naturali, riciclati, la componente estetica e la grafica. Amo la ricerca dell'equilibrio. Mi piace cucinare creativamente. Amo il lavoro di dettaglio, manuale, artistico, artigianale.
