What is the capillary rise?
The capillary rise, that also is called rising damp or moisture lifts is that chemical-physical phenomenon that affects the load-bearing walls that sink into the ground where they have not been interposed (originally) barrier or protective systems by absorption and’imbibition of water.
Over time these walls begin to absorb water from the soil and, all-natural causes, to get back in it by virtue of capillary which microcavities allow the wet lift for more than one meter from the ground below.
How to recognize the humidity lifts ’ (or capillary)?
Being among the most frequent manifestations of wall degradation is also relatively easy to recognize and is caused by the presence of water in the soil.
The humidity in the underground within easy reach of the base of the masonry and, for various mechanisms electrophysical, such as capillarity, Hygroscopicity salina and electric potential differences, manages to climb along the wall.
The phenomenon usually concerns the walls that are located under the ground level, in retaining walls and on the ground floor.
In the walls below ground level (or retaining walls ) You can easily reach the total water saturation d ’ (If the wall is not properly insulated from external ground heatinsulated and scannafossi).
In the walls on the ground floor you have special effects that allow you to distinguish the humidity lifts from other forms of moisture (as the condensation or the generic infiltration due to other factors).
The most distinctive traits are:
– the stain of moisture is almost always uniform and proceeds from the floor upwards, stopping at different heights
– the slick wet edge is well-defined and usually does not exceed the height of almost never an abundant meter
– the stain persists to varying climatic conditions and the internal humidity
– produces continuously leaking sali especially during periods of high evaporation environment (winter heating or summer heat).
What are the effects that this phenomenon may cause?
The process from capillary rise in a masonry is certainly dangerous and irreversible; If left to oblivion and ’ do not activate decisive interventions, the masonry can seriously ammalorarsi to the point of collapse or create very serious and dangerous instability.
The problem is that the water full of minerals that broke up at the height of inhabited environments ’, evaporates from the walls and scatters in ’ warmer air, leaving salt deposits on plaster (as unable to evaporate).
These salts (mainly sulfates, nitrates and chlorides) I'm pretty aggressive enough to ruin the finish with paint stains very showy and re-inflate the plaster, creating a layer of DT anti-aesthetic and dusty.
Because you are the plasters?
The continuous transport of water with high mineral content coming from the ground and masonry, It also causes a substantial rise in saline dilution with the ’ water that carries them. The problem however is when this water evaporates ’ and enter, in the form of steam, about home circles (process facilitated by greater heat and the air drier ’). By this time the salts remain stored content (and imprisoned) on the top layer of masonry that is l’plaster.
With the drying ’ these salts are transformed into solid crystals by increasing its volume of over 10 times.
The continuous and constant process of filing and subsequent riasciugatura, inevitably these salts to saturate the interstitial spaces up to fluff and detach the plasters for excess volume.
At this point the damage becomes a serious problem because from now on the destructive process will begin to attack the masonry degrading, at each cycle, a deeper and deeper part coming, via via, to disrupt the structure like a gangrene.
What & rsquo; & egrave; there mold and how you create?
In addition to the aesthetic and static damage on walls described above, the process leads to problems of unsanitary for livable space.
The excessive evaporation of the walls ’ leads inevitably to saturate the air ’ of the environment making it extremely moist ’. This exaggerated and abnormal intake of water in suspension (in status of steam), will tend to condense on colder spots of ’ environment (usually on the edges of the ceiling and the peripheral walls exposed to the North).
The constant persistence of these droplets condensation (Dew) constantly maintains the wet plaster and ’ facilitates the proliferation of fungi and molds of all kinds.
These microorganisms, that is usually fed with organic content of paints and ’ water in the plaster, begin to reproduce indiscriminately issuing spore harmful to health that propagate in the environment.
These microscopic spores, of dimensions ranging from 1 up to 300µm, soaking environments satureranno lockers, the fabrics, the mattresses, the clothes, the food and will be continuously breathe in by unsuspecting inhabitants.
L ’ nanoscopici excess of these particles can lead to severe respiratory failure, bronchial and serious allergies asmi fed from the same environment that we should instead protect.
Although it may seem a minor problem, bear in mind that the harmfulness of particulate matter, In addition to the allergenic substances value in itself, also depends on their micro size and their ability to reach different parts of the respiratory ’:
more than 7 µm: oral and nasal cavity
up to 7,0 µm: larynx
up to 4,7 µm: primary bronchi and trachea
up to 3,3 µm: secondary bronchi
up to 2,1 µm: Terminal bronchi
up to 1,1 µm: pulmonary alveoli
What are the most obvious moisture damage in an environment?
The damages are huge and tend to degenerate gradually and steadily over time.
– l & rsquo; environment remains constantly dusty due to mold spores and fungi in addition to the seconded salnitri that are expelled by plastering
– showy and halos of humidity spots occur on the hoof and lower parts of the walls of the pressure loss of salnitri
– high presence of dark colored mold almost anywhere on the ceiling making the unhealthy environment and dramatically degraded
– cleaved and falling plaster, crusted and efflorescences colors across the entire perimeter walls
– bathrooms and kitchens tend to be more humid for the vapors of human activity, tend to worsen the problem of ongoing degradation
– furniture and facilities wood spotted, degraded and damaged, very often also mouldy and brittle nails
– excess of fungal spores and mold ’ environment for stray settle anywhere and accelerate the degradation process of foods.
– high level of pollutants and allergens in the air ’ weaken the body and activate ’ often severe States of colds and allergies
– l ’ too wet environment (with high contents of suspended water) make the ’ very cold environment, Heatable hardly with considerable wastage in cash for energy costs
– artificial drying processes such as drying or constant aeration ’, Although decisive only temporarily, does not prevent the degradation of masonry, but rather enhance the salt transport and consequential.
Why is it so important to remove the salt content from masonry?
Because almost all of the water accumulation in the walls depends essentially of these minerals.
Their high Hygroscopicity (that is the natural tendency to absorb water directly from steam or moisture ’) creates large accumulations of water all internal porosity and ’ releases it gradually towards the warmer environment ’ in the form of steam and surface moisture. The continuous process of evaporating maintains constantly the wall colder, moist. Also reduces the original transpiration and ammalora outer surfaces (next to plaster ’) for a problem of continuous mechanical stress due to the expansion of the salt crystals at the time of drying ’.
This process is unfortunately is automatically in a completely automatic and continues until you are unable to eliminate the deleterious effects of salts incorporated in depth.
There are solutions to this problem?
Today's technology provides several solutions to the problem of rising damp:
– mechanical interventions that you get with a real cut of the wall at the base of the floor and the insertion of ’ insulating materials which block the humidity lifts are made with large diamond saws that section literally the masonry horizontally (operation prohibited in seismic risk areas)
– elettrosmotici interventions they produce a reversal of natural electric field and promise a result water down, but it requires a long series of electrodes from sticking in the masonry (with long holes) or special electronic control with RF emission
– evaporating plasters (macroporous or) they are replacing conventional plasters (after demolition) with other special that, Thanks to their porosity allows optimum evaporation rate, quickly absorbing the water from the wall, but making it totally inhabited environment (by increasing the relative humidity and the transport of salts)
– chemical interventions that, similar to mechanical cutting, create a barrier inside the wall, It requires a long and close range pattern of holes in the wall level to inject a chemical much fluid that goes to obstruct the capillary walls sigillandole. Requires a long aeration because this product incorporated in the wall, is smelly and toxic to many months after the application ’.
All these steps (often decisive and not of short duration) considerable construction and require expensive and rather long time resulting in the need to move away from home ’ as long as the work will not be completed. They are invasive, dusty, hazardous to your health, and some create lightening despicable in structural seismic risk zones.
Why use IgroDry instead of other systems?
– because IgroDry is a real technological innovation and represents, at the moment, the best method (and the less invasive) for the dell ’ humidity treatment walls
– because IgroDry is the only product that ’, penetrating naturally in wall, neutralizes the salts incorporated, ejects the water ’ and eradicates mildew fungus and spores annientandone
– Why IgroDry allows the simplest and cheapest treatment ever proposed in the market (calculated to Syed)
– Why IgroDry, converting salt content of masonry, It cancels the effect of hygroscopic ’ and retention, restoring the natural transpiration
– because IgroDry is easily applicable by brush (or spray) and heal immediately the walls showing all the ’ effectiveness even after few hours
– because IgroDry does not require invasive construction, Neither holes, or accessories, or substances or plates to be inserted into the masonry, No electrical or radio frequency
– because IgroDry is a very high-tech non-toxic fluid that you can apply yourself to save on labor costs
– because IgroDry offers ’ moisture effective and lasting action in time and, like a painting, can be applied at all times and only where necessary
– because IgroDry is versatile and does not restrict the livability of the environment be treated in ’ when does not smell, is non-toxic, It does not produce harmful pollutants and dust nor does not require construction work, demolition, recoveries, equipment, holes or cuts to be applied.
