Hello everyone,
maybe someone here can help me from experience.
I want to make a foundation myself for our air heat pump at the beginning of next week. In the foundation plan from the company Vaillant, it says to fill about 80 cm of the approximately 1 m deep foundation with permeable coarse gravel and the remaining 20 cm with gravel. The pump will later be placed on 2 strip foundations. The problem now is that my heating engineer is on a two-week company vacation and is not reachable... But I have to finish the foundation because the paving work will continue the week after next and everything should then be neatly integrated.
My question:
What is meant by permeable coarse gravel? The building materials supplier says the term is too general...
Can't you just use washed Rhine gravel or something similar in 16 - 32 mm and fill the entire foundation with it? A 100 mm KG pipe about 80 cm long will also be installed in the foundation so that the condensate can drain away.
Has anyone done this before?
I would appreciate feedback.
Regards
Heiko
