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.
