Protectosil® Water repellents

Moisture is the root cause of almost all mechanisms that damage mineral building materials. The porous nature of many substrates allows water and dissolved contaminants to penetrate via capillary suction into the pores.

This may cause various problems such as corrosion of reinforcing steel, salt burst, or freezethaw damage. There is no doubt that by preventing water ingress into a structure, damage is drastically reduced. 

Treatment with water repellents – called "hydrophobization" - using Protectosil® building protection products is unique. Protectosil® water repellent products penetrate deep into the substrate. They keep water out and maintain the substrate's water vapor permeability. 

Very alkaline substrates as concrete can be protected for long period of time.
