WHY COVER SURVEY?

Cover Survey: Achieving the specified cover is of paramount importance if the building owner is going to achieve the planned design life and economic return from his building. Did you know that “If a building with a 50 year design life has a minimum cover of 20 mm, a cover reduction of only 2 mm reduces the expected life by 10 years? In an extreme case reducing the cover to 10 mm reduces the life from 50 years to 12 years.”

So, cover thickness remains one of the most important durability parameters. An appropriate remedy is to check the cover by NDT after construction and where cover is found to be inadequate to provide a prescribed treatment that would effectively provide all the protective functions of Cover.
