Hello,
we are currently planning the garden, and as part of this, we want to lay an underground cable at the back of the garden. For this, a conduit (a standard corrugated pipe) has been installed from the fuse box in the basement through the basement wall to the outside. The corrugated pipe ends about 50cm (20 inches) outside the basement wall.
If I now install an underground cable, I would prefer not to lay it directly in the soil but also protect it with a corrugated pipe, as is commonly recommended.
How can I extend the corrugated pipe from the basement wall in a watertight way? Are there watertight sleeves, sealants, or similar products available for this purpose?
As an alternative, it might also be possible to seal the corrugated pipe watertight (after pulling through the underground cable) using silicone or well foam, and simply lay a second corrugated pipe alongside the first one through the garden without using a connector.
How is this usually handled? Surprisingly, I cannot find much information about this online...
