Drying & Water Damage Restoration

Water damage occurs slowly or suddenly, it becomes visible as small, damp spots, but can also occur in the form of massive amounts of water. There are countless ways in which and to what extent water can become a problem. For those affected, it is important to get serious advice from a specialist and to commission a well-known company with the drying out work.

Seriousness and competence

The cause and extent of damage cannot always be clearly identified at first glance and numerous questions arise.

  • Is there a line defect?
  • Is moisture penetrating through your roof?
  • Are you dealing with delayed water damage?
  • Is it a question of pushing moisture?
  • Is there too little ventilation or insufficient heating?
  • Is there too much residual moisture in the building?
  • Is there possibly a second water damage?
  • Which parts of the building are affected?
  • What is causal?
  • What immediate action should be taken by you?

Only specialist knowledge and experience enable clear answers.

During the inspection of the damage, the technician takes a moisture measurement, determines the total extent of the damage, determines the most effective drying method and determines which work has to be done to restore it.

Due to a lack of experience and knowledge, laypeople cannot assess whether natural drying can take place (i.e., “whether something will dry out on its own”) or whether it is necessary to set up drying equipment.

Technical Drying Out Is Only Offered If It Is Actually Required!

Adsorption drying

This type of drying is used to dehumidify structures such as screed structures, wall cladding and ceiling structures.

An adsorber is used to generate dry air. This device draws in room air (or outside air) and emits moist air on the one hand and extremely dry air on the other (with 1-2 g H 2 O per m 3). The moist air is led outside, while the dry air is used for drying out. With the help of side channel compressors (gas ring compressors) this dry air is blown into the structure to be dehumidified.

Such a combination of adsorber and side channel compressor forms a so-called drying system (or drying unit), with adsorbers with an air output of 100, 150, 200 or 300 m 3 of dry air / hour being used depending on the extent of the Water damage restoration Potomac.

 

The advantages of adsorption drying essentially consist of the following points:

  • Full drying performance from the first minute
  • High efficiency even at low temperatures
  • Maintenance free
  • All devices can be outsourced, so there is little to no noise pollution
  • Drying of floor structures is also possible from the lower story through the ceiling (= drying from bottom to top) and vice versa
  • If the building is only dried out, the living behavior about ventilation can be maintained. In summer there is no room heating due to closed windows and doors.
  • Precise traceability of the drying progress through regular measurement of the difference in humidity in the air flow

BloVacDry

To meet the current trend towards more hygiene. Based on the principle of adsorption drying, the damp air flowing out of the screed joint of the construction to be dried, which may be enriched with undesirable microorganisms, is to be captured by means of a film system and passed through a Hepa filter.

The installation of the air collection device takes place with little technical effort and without serious interventions in the construction, only the dismantling of the edge strips is necessary.

BloVacDry can also be used for drying out by suction. Dry air is blown into the construction by means of an adsorber, the moist air is sucked out of it by negative pressure and discharged through a filter with the aid of the patented air collection system.

The pollution of the room air can thus be avoided in any case.

Another plus is the reduction in the number of drill holes required by the BloVacDry system.

Regardless of whether the drying is carried out using the pressure or suction method, BloVacDry offers all of the advantages of adsorption drying described above.

The dehydration takes place in a self-contained system that is efficient from the start and everyday life around it remains almost unaffected.

The condensation drying

With condensation drying, the moisture in the room air is removed by condensers.

This type of drying is used for superficial moisture penetration, for building and shell dehumidification. In order to achieve higher efficiency, fans are installed in combination with the condensation dryers for better air circulation.

However, there are the following disadvantages with condensation drying:

  • Closed rooms are required
  • The water tank has to be emptied, therefore not maintenance-free
  • Low efficiency at low temperatures

If condensation dryers and side channel blowers are combined when building structures are dried out, there is no possibility of relocating the equipment, as the rooms must be closed when using condensation dryers.

This type of drying is the event of moisture damage to pure wooden structures, as otherwise there is a risk of over drying in these cases.

Heat drying

Drying by means of heating takes place either with IR heating plates or by drilling in heating rods.

These methods are used with deeper lying moisture in solid masonry where no dry air purging is possible (e.g., in stone masonry). The heating of the affected components accelerates the vapor diffusion. It is therefore advantageous to remove layers of paint and salty plaster before drying.
