After having removed the cause of the water damage, the damp walls,
the floor and insulation need to by dried in order to avoid mould and
bacterial infestation. The drying process is particularly important for
the insulation layer underneath the screed.

Sustainable drying of water damage

Water damage restoration of ISOTEC:

The cause: Damp screed insulation layer underneath the screed

Moisture penetration is usually caused by water damages or deficient sealing. Warmth and humidity offer the ideal prerequisites for the formation of mould. It may appear after only 10-14 days. For this reason, it is important to dry the damp insulation layer as fast as possible.

Our 1st step: Installation of air intake hose

Our drying machine will absorb the air from the damp screed insulation layer through air intake hoses - either via border joints or particular air intake openings.

Our 2nd step: Drying

Condensate dryers dry the air which will then be blowed underneath the screed via screed border joints. The dry air absorbs the moisture of the insulation layer and all cavities underneath the screed. The drying machine then purifies the air in several steps.

Our 3rd step: Controlling/Measuring

Our ISOTEC Drying System reliably eliminates the moisture of the insulation layer underneath the floating screed. Through regular controls we determine the state of the drying process.

Building drying: satisfied customers

Castle of Mannheim | Defect: Damaged pipe

The ISOTEC Group has successfully sealed more than 100.000 properties in Germany, Austria and Switzerland in the last 25 years.

The castle of Mannheim was built between 1720 and 1760. A broken pipe at the castle led to considerable damages. ISOTEC executed a technical drying process so visitors could enjoy the beauty of this baroque jewel anew.

Building drying on the suction method

Mould may emerge underneath the insulation layer after just 10 to 14 days. This presents a potential health risk to everyone using this space. In order to minimize the microbial contamination, we generally apply our intake method for the drying of water damages.

In order to prevent any additional contamination of the area which needs to be renovated, the drying machine immediately purifies the air intake through several filters (amongst others, HEPA filter). Those filters eliminate spores and other mould components from the air up to 0,001mm. The purified air is then returned to the room where it is dried through a condensate dryer.


Your benefits at a glance

  • Quick and secure drying

  • Conservation of flooring

  • Re-establishment of the acoustic and thermal insulation function of the screed insulation layer

  • Vorbeugende Maßnahme, um ein Schimmelpilz- oder Bakterienwachstum zu verhindern.

  • Preventive measure to avoid the growth of mould and bacteria


  • This procedure is also recommended in the "Mould repair guide" of the German Federal Environment Agency.
