Water damage and its consequences

Water damage can be caused by leakage (9) or by moisture under the floor (9).


Possible cause: Leaks

In cases of water damage, a lot of water can penetrate the building in a relatively brief time.

The causes can be faulty water pipes or damages resulting from floods.

The newer a building, the more complex is the often invisible network of pipes within the building. Where in the past there were generally only two places in each apartment for accessing water, with the same number of supply and waste pipes, this number is significantly higher today.

Underfloor heating, a guest toilet or a sauna requires additional pipework that increases the potential for water damage. Basically: before using machinery to dry out this kind of damage, the cause must first be localised.

Special case: the insulation layer under the floor screed is wet

Modern floor screed constructions “float” on the foundation slab. Here, dampness can get under the floor screed and penetrate the insulation layer unhindered.

Once there, the dampness cannot dry out by itself. The massive layer of floor screed over the insulation prevents the possibility of collecting or wiping up the water that has got in.

This means that action is urgently needed!

Dangers after water damage

If water has penetrated the wall or the insulation layer under the floor screed, you must act quickly, because experience tells us that microbial growth of bacteria and mould in and on damp construction materials begins after 10 to 14 days, depending on the specific building conditions.

Dampness in walls and floors must be reduced to a “normal level” of balanced moisture in the construction material as quickly as possible. However, to optimise the time this takes, it must only be done with machine-drying processes.
