questions William Ferdinandsen on 27/02/2017
Question: In general, how long does the product last on a new bridge in a marine environment? In other words, how long before the product should be re-applied? Thank you, Bill
Answer: 

Sika do not offer design lives for these types of products, but it is fairly common place for hydrophobic impregnations to be re-applied every 2-3 years. However that is if the product is used singularly instead of as a full part of a concrete repair system.
