Influence of Cracks[3]
• Objective of the Study:
• To show the influence of crack in the effectiveness of
hydrophobic treatment using different types of product (high
active content silane liquid or cream, low active content
silane/siloxane)
• Summary of the results:
Importance of the type of product used in the durability
behaviour
Best performance achieved with cream Silane
No long term protection achieved with low active
silane/siloxane
Effective protection achieved even if the treatment occurs
before the crack appears

Standard Tests (Alberta B388)
Classification:
Type 1: Penetrating sealers for use of traffic bearing exposed
to abrasion
Type 1a: for sheltered conditions – relative moisture
content of substrate not exceeding
55%
Type 1b: for outdoor condition where the relative
moisture content of substrate not
exceeding 70%
Type 1c: low VOC, high performance. For
application in outdoor conditions to
new bridges and overlays cast with
low water cement ratio (0,30 – 0,45)
where the relative moisture content is
maximum 80%
