Note for small numbers of bottles:

Circulating moisture - partial treatments do not work!

! Note: Circulating humidity with a low number of bottles

Initial hydrophobization: Partial treatments (e.g. "only half at first") do not work - the moisture circulates around the short section. The following applies to initial restoration: always seal the entire wall. ➜ C alculate the quantity in the calculator.

⚠️ Too few bottles → no closed barrier. If only a short section is injected, the moisture can circulate around the treated zone and continue to rise by capillary action. A continuous barrier line is required for reliable hydrophobization.

What is Isofin®?

Isofin is a purely organic, water-free, hydrophobic, polymer-based capillary water barrier that allows you to get your moisture problem under control and save money in the process. Isofin is effective against rising damp and laterally penetrating damp. It penetrates deep into the masonry and forms an invisible barrier that effectively repels non-pressing moisture. By simply inserting the Isofin bottles into pre-drilled holes, the product is distributed evenly and thus ensures complete protection. This not only preserves the building fabric of your home, but also increases your well-being through a dry and healthy indoor climate.

Example: Horizontal barrier

How does Isofin® work?

Isofin® is a hydrophobic barrier system that impregnates masonry to repel water without clogging the pores. It works in a similar way to the impregnation of fabric or suede, repelling liquid water but allowing water vapor and air to pass through. In contrast to leather, which has to be re-impregnated regularly, Isofin® guarantees this hydrophobic effect for a lifetime.

Once hydrophobized, the masonry permanently retains its water-repellent properties without the need for re-treatment. This is also crucial for masonry in order to restore its natural function and thermal insulation.

Contrary to popular belief, the distribution of the injection agent does not depend on its solubility in water, but on its insolubility in water and its low surface tension and viscosity. These properties enable Isofin® to distribute itself and displace water in water-saturated masonry.

Further information can be found in the Isofin® manual.

Isofin® molecular technology for creating durable, hydrophobic capillary water barriers against rising damp and lateral moisture penetration, for renovating walls made of mineral building materials.

Isofin® is not silicification, not aqueous silicification and contains no nanoparticles! Free from salts and other building-damaging ingredients. Stops salt efflorescence and prevents the rotting of masonry and concrete.

Isofin® instructions:

Permanent protection against moisture in three simple steps:

1. measuring and drilling
Carefully measure the affected area and drill the holes according to the specified instructions.
 

2. application
Insert the Isofin® bottles into the prepared holes.

3. allow to dry
Allow the wall to dry completely to activate the moisture barrier.

Once applied, Isofin® offers long-lasting protection. Your home remains permanently hydrophobic. You can rely on our 20-year guarantee, although the protection often lasts far beyond that.

Materials Testing Office confirmed

Up to 98% less water absorption

The study by the Dortmund Materials Testing Office impressively demonstrates the effectiveness of Isofin®. The treated sand-lime brick absorbed up to 98% less water than the untreated brick. This significant reduction in water absorption confirms that Isofin® effectively protects your masonry from moisture and thus ensures the longevity and health of your property.
