Sealing buildings - ISOTEC sealing systems protect against humidity damage
When you find damp in the walls it’s important to act quickly in order to prevent further damage and minimise possible health risks. If you suspect there is humidity penetrating the building, you are advised to consult an ISOTEC expert as soon as possible, because it is only by using the most advanced technology and the help of a professional evaluation that the full extent of the damage can be assessed properly. Our specialist will then decide whether it’s better to insulate the masonry from the inside or the outside, and whether to use a horizontal barrier or a surface injection.
If the sealant is damaged or non existent, water will seep in and cause humidity problems. Often, the damage will only become visible many years later when the first signs of mould appear. It is quite common for cellars to smell vaguely of mould and feel humid, but excessive humidity in the masonry can be dangerous. The ISOTEC sealing measures provide lasting and sustainable insulation for buildings and help us feel comfortable and secure again.

Paraffin, a very flowable wax, permanently blocks the pores of the masonry. Capillary moisture no longer has a chance. The procedure may only be carried out by our authorised ISOTEC specialist companies.

If moisture enters the cellar from the side via the walls, the same damage mechanisms always set in. Our ISOTEC exterior waterproofing provides reliable protection against moisture penetrating from the side.

Particularly if the damp walls are not accessible from the outside, our professionally carried out interior waterproofing is a technically sensible

In the case of a defective wall-sole connection (or joint) and cracks in concrete components, our ISOTEC flex tape system offers a long-term secure method to successfully seal the cracks and joints.

After the installation of a subsequent waterproofing, the drying phase of the masonry begins. Especially in older buildings, the drying of the remaining moisture is often associated with the efflorescence or crystallisation of the salts that are harmful to the building.
