Core bores

Perfect bores are required for installation. As hairline cracks may

be present in the concrete or could be caused by processing, it is

advisable to seal the entire length of the borehole wall with suitable

sealant (such as AQUAGARD).

Tightness can only be guaranteed if this recommendation is fol-

lowed.

Installation / trench in

fill

To avoid deformations at the sealing point, it is especially important

during installation and when

filling the trench to ensure that no subse-

quent sinking of the pipe can occur. We also recommend that the pipe

is supported or suspended inside the building. Tightness cannot be

guaranteed unless these recommendations are followed.
