Core drill holes

Prerequisites for installation are perfect drill holes.Since hairline cracks can exist in concrete or canarise as a result of the work, we recommendsealing the drill hole walls over the entire lengthswith a sealant

We cannot guarantee a good seal if theserecommendations are not observed.
