FREQUENTLY ASKED QUESTIONS

There are many arguments that confirm that the best system for removing moisture by capillarity in basements and cellars is the electrophysical system HS-221 from Humitat-Stop.

• The HS-221 is installed in less than 3 minutes, and it is a global solution for the entire ground floor or basement, while prior to injections must perform works to find injection points, make more than 500 deep injection holes in the wall, for a plant of 100m2 and if you only inject into the walls with moisture these will come out on the adjoining walls.
• The HS-221 is not only much more effective, it is much cheaper than injections. For a plant up to 150m2 you can get an HS-221b from €2,284 + VAT or the low-cost model L150 for €1,045 + VAT while the cost of resin injections to protect a plant of 150m2 would be more than €10,000 with several working days.
• The HS-221 in addition to removing moisture by capillarity of the walls, also removes the moisture that rises between the floor tiles while resin injections do not protect from moisture that rises through the soil. .
• The HS-221 is powered to 12VDC through a power supply or solar plate and consumes less than 1W, or less than 10 € per year, whereas the injections do not need electric current.
• The HS-221 is ecological and certified not to be at all harmful for the health of animal people and plants, however the injections of resins in the base of the walls end up contaminating the aquifers, because over time they degrade.
• The HS-221 comes with a guarantee that walls and floors will dry, or your money back. Resin injections do not come with a guarantee of wall and floor drying, and certainly not floor drying..
• The HS-221 system works with any type of wall and floor construction material such as brick, concrete blocks, concrete. stone or wall tiles. Resin injections can work on brick walls or concrete blocks, but it is not possible to make an impermeable layer on very thick walls or tapestries as in the case of village houses. Nor does it prevent lateral moisture in basements or underground walls.

The HS-221 system is a substantial improvement over wireless electro-osmosis as can be seen:

• Low-frequency electromagnetic waves transmit 12 times better through walls and floors than through air, which is why this type of transmission is used in the HS-221, while Wireless electro-osmosis transmits a radio frequency through the air and therefore it is difficult to dry thick walls. As a result, the HS-221 dries 4 times faster.
• An important consequence in transmitting through walls and floors is that in the HS-221 models are classified by m2 of plant or basement surface, while in electro-osmosis it is transmitted by air and equipment is classified by radio coverage. A clarifying example is, that for an elongated plant of 20mx5m it is covered with HS-221a of 100m2 of coverage, but needs with classical electro-osmosis a radio device 11m to cover the corners, which is much more expensive than the type HS-221a.
• With a single HS-221X it can cover plants up to 2500m2 which can be elongated, but with classical electro-osmosis systems it can at most cover an area with a coverage radius of 16m, and need several machines to cover the entire plant.
• When transmitting radio frequency electro-osmosis systems by air, it may cause interference with equipment such as radio, television, alarms, remote controls, or pacemakers, while the frequency used by the HS-221 system does not affect any electronic apparatus, and does not cause any interference, because it also hardly emits by air.
• Because wireless electro-osmosis systems are slow to dry, vendors require the use of expensive special mortars, which delay the effects of moisture on the walls, to allow time for drying to take place. The HS-221 system does not require special lime mortars or expensive special paints.
• At full capacity the electrical consumption of the HS-221 is less than 1W, while the classical electro-osmosis systems are in the order of 12W in normal operation mode, the annual electricity expenditure for the HS-221 is less than €10, Wireless electro-osmosis is around 120€..
• The warranty of the HS-221 system is 30 years because it consumes very little and does not heat up, while the warranty for systems with classical electro-osmosis is 7 to 10 years because they are much warmer and less reliable.
• The HS-221 system gives a guarantee of drying in maximum in one year and if not the money paid including the VAT is returned, while the systems with wireless electro-osmosis give the guarantee to return the money paid if they do not dry.

Soil moisture usually appears between the tiles, leaving a trace of saltpeter. If there is wood parquet it swells and deforms.

Do not think of solving it by putting a waterproof layer under the parquet or tile, because the weight of the building material itself punches through it, and it is also a very labor-intensive solution.

An effective and durable solution is to place a HS-221 fixed on the adjoining thick wall and the capillary lift moisture in the soil.

If the moisture is caused by a leak from a groundwater pipe, or a well with the level less than 50cm to the ground, then these leaks have to be resolved before drying.

The so-called foundation moisture is the capillary moisture that rises from the foundation, and its solution is the same as for the rising damp.

Before construction, it is advisable to divert underground currents, although this can be difficult and expensive.

The Electro-Fiscal solution is the most effective, economical and maintenance-free, solving the problem in a few months, provided that the floor support screed is at least 10 cm thick, to facilitate the transmission of water-repelling waves to the subsoil.

In this case, if no water enters by filtration, the moisture is effectively resolved by capillarity which, in addition to acting from bottom to top, also act laterally.

In this case it is advisable to use at least the model HS-221a.

The problem is also solved on the ground floor, as long as they have common lifting walls.

The process is simple:

You send us by email to info@humitat-stop.com your details in order to make a proforma invoice.

We send you the proforma invoice with the details of the account where you should make the transfer or deposit.

If you send us a copy of the payment document by email after the payment has been made, the equipment immediately leaves and arrives in three days.

Installation is as simple as making two holes in the wall about 20cm from the ground with 5mm drill bit and at a distance of 10cm, place the supplied studs, Put the two crowns leaving a margin of 3mm to the wall, and hang the HS-221 as if it were a picture.

Plug it in with the supplied power supply, and a red LED lights up to indicate that the power is coming in, and a green LED indicates that it is already working properly.

Check that these LEDs continue to light up over time to make sure the rising damp removal and watch the corresponding video.

If moisture is considered to be distributed throughout the house and the floor is rectangular, it would be placed towards the middle of the longest peripheral wall in a humid area.

You can cover the equipment with a non-metallic box, or place it in a wall-mounted cabinet.

If the humidity is concentrated in an area, apply the criterion in that area, it being important to place the HS-221 on a master wall with rising damp.

For ground-floors made of bricks or concrete blocks, the walls dry out in less than 4 months.

To the other end for thick walls made with stones, sand some cement, and everything they found (typical village house)can dry out in a maximum of 9 months. In this case, the electro-osmosis systems would take at least 2 years

Humitat-Stop gives a 30 year warranty with repair free of charge for any breakdown, and a drying guarantee to return the amount paid if we do not dry your walls and floors after one year and before two, following the measurement method indicated in our manual.

The HS-221 complies with the regulations of electromagnetic compatibility, and does not interfere with alarms, wifi, radio, tv, nor pacemakers.

It is basically transmitted through the walls and barely through the air.

The equipment has a very low consumption of 0.7W representing 6.1kW/h per year, which is negligible, although it should always be running.

In a year the HS-221 spends less than a TV in a day.

This equipment continually counteracts the physical effects of capillarity and doesn't have any consequences in the event of a power interruption. However, if the current is absent for more than 15 days, capillary moisture could reappear.

Since it's powered by a converter that transforms alternating current into 12VDC, this equipment can also be operated using solar cells with a rechargeable battery to provide 12VDC power during the night.

The initial step involves drying the wall affected by capillary moisture (rising damp), followed by the elimination of salts that manifest on the surface. This can be achieved through gentle brushing, using rags, or employing chemical solutions. However, when substantial wall damage is caused by moisture, we strongly recommend wall repair. This recommendation is particularly relevant if the wall's plaster has absorbed moisture and consequently deteriorated, transforming into a hygroscopic material that absorbs ambient moisture, leading to surface dampness even though the interior of the wall is dry.

Damaged areas should be meticulously restored using high-quality lime mortar. In cases where paint is involved, silicate paint is recommended for application.

Occasionally, restoration work commences about fifteen days after the installation of the equipment, utilizing top-grade lime mortar. It is important to acknowledge that over time, inconsistencies in wall appearance may arise.

In current times, certain restorers have attempted to address capillary moisture by employing substantial layers of lime mortar (1cm), preceded by an adhesion-enhancing layer applied to the wall.

Although this approach temporarily delays the effects of capillary moisture for up to 3 years, it eventually leads to a recurrence of the issue. This recurrence occurs when the water-dissolved salts saturate the mortar layer, reinitiating conflicts.

Lime mortar serves as a suitable complement for combating capillary moisture, as it enables immediate wall restoration. Within a span of 4 months, the walls will be thoroughly dried and will not be saturated with salts, thereby preventing the formation of chips. Consequently, the thickness of the lime mortar layer can be reduced to a mere 5mm.

The initial step in addressing the issue is the eradication of mold, given its potential health risks, including allergies, rheumatism, and asthma.

In addition to commercial anti-mold products, there exists a home made solution involving the use of a spray bottle filled with a mixture of 4 parts water and bleach. This mixture can then be sprayed onto the affected areas of the wall.

However, it's important to note that if the underlying moisture issue is not resolved, mold is likely to reappear.

When applying this solution, it's crucial to exercise caution. Protective gloves and eyewear should be worn, along with clothing that provides full coverage.

This equipment effectively counteracts capillarity; however, it does not reduce the water level in the vicinity.

Based on our experience, we've found that it performs optimally when the distance between the ground and the water level exceeds 50cm.

The geomagnetic system operates by utilizing the Earth's magnetic field. Through the use of a coil and a capacitor, it shifts phase to counteract this field, thereby inhibiting the ascent of moisture created by water molecule dipoles along the walls.

Despite not consuming electricity, this system's efficacy is notably limited due to its variable intensity and frequency. In optimal scenarios, it requires up to 3 years to effectively dry the walls. In contrast, the HS-221 accomplishes the same task in less than 4 months.

This device is primarily designed to address rising damp. However, when used in ground floors and basements, it significantly diminishes moisture caused by capillarity-driven processes, thereby also alleviating moisture stemming from condensation.

For instances where condensation-related moisture remains prominent, its resolution involves improving ventilation within the affected area. This can be achieved by periodically refreshing the air on that level and employing an extractor whenever steam is generated through activities such as cooking or showering.

Using dehumidifiers to address capillarity-induced moisture is a grave misjudgment, as it exacerbates the issue. Capillary action causes water to move upwards through walls, with a portion of it evaporating from the wall's surface.

Introducing a dehumidifier amplifies this evaporation process, subsequently enhancing the upward movement of water. This forms a detrimental cycle that drains the accumulated water from the dehumidifier, yet fails to rectify the root problem. Moreover, this process accelerates the deterioration of walls.
