Sistema HS-221
  • Our Electro-Physical system is the most efficient in terms of time and cost for completely removing moisture by capillarity (rising damp) from walls and floors.
  • Equipment CERTIFICATE CE in Europe, FCC in USA and ICNIRP, ensuring it is not harmful to the health of people, animals, and plants.
  • Equipment is ECOLOGICAL and SUSTAINABLE, avoiding the need for injecting chemicals into the walls or conducting any construction works.
  • System comes with a 30-year warranty and satisfaction guarantee.
  • By removing moisture by capillarity (rising damp), it prevents the appearance of mold, and the proliferation of insects.
  • Not only does it requires no maintenance , but it prevents breakdowns in appliances by removing rising damp on the walls.

Types of moisture

 Resolve  the rising damp with HUMITAT-STOP

Rising damp

This type of humidity comes from the subsoil and rises through the walls and between the floor tiles. Our Electro-Physical system HS-221 is a breakthrough in wireless electro-osmosis, because it transmits through the walls rather than through the air, thus managing to dry 4 times faster.

condensation moisture in windows and ceiling

Condensation moisture

Condensation moisture is caused by the cooling of water vapor that has originated in the house during activities such as cooking, showering, using the washing machine, etc., during the night. This moisture appears in the corners of the walls, floors and ceilings as well as in poorly ventilated areas, affecting clothing and footwear.

water filtration in walls and roofs.

Filtration moisture

It has diverse origins such as:

  • Cracks in waterproofing and sealing on terraces, walls, and roofs.
  • Leaks or cracks in water pipes.
  • Underground currents that rush against the walls.


Humidity at home appears on both exterior and interior walls


Moisture at home is very dangerous, because it affects the health and economy of all its inhabitants.

humidity in the ground, causes paint damages, creating chippings on the walls


The most common humidity in ground floors is the rising damp, which rises from the subsoil by walls and floors.

 Moisture by capillarity affects the basements appearing stains all over the wall


Humidity in basements is usually due to capillarity, both from top to bottom and laterally.

Capillary moisture rises through the pores of the walls


The humidity in the walls can be due to capillarity, condensation or filtration, and the solution depends on the type.

Moist soils leave traces of saltpeter


In the floors, humidities appear due to capillarity or filtrations, and they can be differentiated with a thermal camera.

Humidity in garages appear on floors, walls, ceilings and columns


Although the three types of humidity can occur, it is necessary to check the proper sealing of the walls with floor and ceilings.

Drawback of waterproofing injections for removing rising damp

March 24th 2020

Injecting resins or gels into the walls, apart from the cost and mess, entails a number of problems such as:

  • Aesthetic and structural damage to the wall occurs when making a hole every 5 inches.
  • Ineffective for drying very thick walls, narrow partitions, floors, and basements.
  • If you only inject the walls with moisture, it will come out of the adjoining walls.


Optimum efficiency in drying moisture on walls and floors
Maximum speed in drying walls and floors

July 23rd 2023

Maximum speed and efficiency are achieved in drying of walls and floors affected by capillary moisture (rising damp) by installing the HS-221 Electro-Physical Humitat-Stop System.

This electronic system, without any construction works, can dry a wall of bricks or concrete blocks in less than 4 months, and walls of old village houses up to 30 inch thick in less than 9 months.


Answers to frequently asked questions

Effectively dries moisture on walls and floors of ground floors and basements
Does it also work for dampness in basements?

In that case, if no liquid water enters, the system-HS-221 solves the capillarity humidity by (rising damp) of the walls, which not only acts from bottom to top, but also laterally.

In basements moisture can appear due to condensation which is removed by extracting all the water vapor, generated inside.

In the case of humidity in the basement and ground floor, placing equipment in the basement also solves the problem on the ground floor, provided they have common load-bearing walls.


The right model is chosen depending on the  m<sup>2</sup> of the ground floor or basement.
What is the right model for my ground floor or basement?

To remove moisture caused by capillarity, you should choose the appropriate model depending on the square meters m2 of the ground floor or basement, regardless of its shape.

Depending on the model, the HS-221 system can dry areas from 50m2 to 2500m2 and is available in various sizes, including 50, 100, 150, 200, 300, 400, 1250, 2500m2.
