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. ## Waterproofing from a professional - all systems at a glance [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. ##### Horizontal barrier](https://www.isotec.de/en/santa-ponsa-mallorca/workmanship/horizontal-barrier "Horizontal barrier")[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. ##### Exterior sealing](https://www.isotec.de/en/santa-ponsa-mallorca/workmanship/exterior-sealing "Exterior sealing")[Particularly if the damp walls are not accessible from the outside, our professionally carried out interior waterproofing is a technically sensible technically sensible alternative to sealing from the outside. ##### Interior sealing](https://www.isotec.de/en/santa-ponsa-mallorca/workmanship/exterior-sealing "Interior sealing")[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. ##### Crack injection/flexible tape](https://www.isotec.de/en/santa-ponsa-mallorca/workmanship/flexband-system "Crack injection/flexible tape")[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. ##### Restoration plaster](https://www.isotec.de/en/santa-ponsa-mallorca/workmanship/renovation-plaster "Restoration plaster") ## Exterior sealing #### Before-After Comparison ## Our References [ More References and Reviews ](https://www.isotec.de/en/references)- Interior sealing - Villa, Port d`Andratx - Damage: leacking concrete components [ View Project ](https://www.isotec.de/en/references/references-detail?tx_isotecreferences_plugin%5Baction%5D=showReport&tx_isotecreferences_plugin%5Bcontroller%5D=Reference&tx_isotecreferences_plugin%5Breport%5D=2035&cHash=2ef70fae7a8bcd8f000e6b18c7f20b24 "View Project Villa, Port d`Andratx") - Sealing with liquid plastic - Villa, Port Andratx - Damage: damage of balcony/terrace, chipping plaster [ View Project ](https://www.isotec.de/en/references/references-detail/professionelle-terrassensanierung-auf-mallorca-mit-fluessigkunststoff-der-weg-zu-einer-nachhaltigen-loesung "View Project Villa, Port Andratx") - Horizontal barrier - Climate board - Sealing with liquid plastic - Interior sealing - Villa, Cala Pi - Damage: humid walls, damage of balcony/terrace, mould [ View Project ](https://www.isotec.de/en/references/references-detail/villa-mit-feuchtigkeitsschaeden-in-cala-pi-wird-zu-einem-wohlfuehlort "View Project Villa, Cala Pi") - Interior sealing - Renovation of balcony - Sealing with liquid plastic - Villa, Puerto de Pollenca - Damage: humid walls, damage of balcony/terrace [ View Project ](https://www.isotec.de/en/references/references-detail/terrassensanierung-auf-mallorca-mit-isotec-fluessigkunststoff-professionelle-abdichtung-fuer-langanhaltenden-schutz-1 "View Project Villa, Puerto de Pollenca") - Exterior Sealing - Renovation plaster - Einfamilienhaus, Costa de la Calma - Damage: humid walls - Horizontal barrier - Interior sealing - Einfamilienhaus, Portals Nous - Damage: humid walls - Interior sealing - Einfamilienhaus, Genova - Damage: mould - Sealing with liquid plastic - Sealing of wall/floor junction - Einfamilienhaus, Capdepera (Costa de Canyamel) - Damage: damage of balcony/terrace José-Alberto Remesal Weinbrecht Geschäftsführer Questions?

ISOTEC offers masonry waterproofing in the form of exterior or interior waterproofing, horizontal barriers or joint sealing. #### What are the consequences of poor or defective sealing? If the waterproofing does not function properly, deposits of salts, mould growth, dry rot, plaster spalling and cracks in the foundation can cause considerable damage to a property. # Sealing In the case of damp walls, quick action is required to avoid further damage and health hazards. If there is a suspicion of moisture penetration, an ISOTEC specialist should be consulted as soon as possible. Because the extent of the damage can only be correctly assessed with the help of the latest technologies and expert evaluation. Our specialist will then decide whether masonry sealing can be better achieved by exterior or interior waterproofing or a horizontal barrier.
