Clues for keeping water out
Humidity is the main cause of almost all damages in building materials. Due to porous surfaces of structure materials, moisture and dissolved polutant substances penetrate into that pores with capilary absorption. This situation causes deteriotion on reinforced concrete steel bars, salt attacks or freeze-thaw deformation.
When moisture penetration is hindered, damages on materials decrease. So, how are moisture penetration hindered? With water repellent, also known as “Hydrophobation”, using Protectosil® structure protection products can give outstanding results. Protectosil® water repellent products penetrate directly into surface. Thus, water can be kept out and water vapor permeability can be provided.
Deep hydrophobation for most suitable protection
Water repellent molecules of Protectosil® are smaller than the surface pores. When this situation and low viscosity are considered, water-repellent molecules penetrate deep into structure materials and react with inner wall pores. While water penetration into pores are hindered, in the same time, water vapour can pass through pores. Structure is breathable with this way. Photos down below show simplified examples.
There are two main adventages comes with deep penetration. UV lights and mecanic effects do not damages. Silicones and siloxanes are bigger then 20nm, so they can not penetrate easily and have damage casued by streching.
Protectosil® hdrophobic productions creat deep barier against water. Efficiency of Protectosil® products is not considered with pilling effect. It depents decrease of water amout. Observing their nondestructive effects can be tested on existing structures with Karstens (or Rilem) tubes. Water based ink with using core drill is another test method to determine depth of penetration.
Succes of water-repellent product on surfaces exposed high traffic
Water penetration level into concrete was measured before and ten year after exposing high traffic.
How high decrease of water penetration level means that much protection on surface in 10 years.
