Hello Sylla,
"only" 1.5 m of peat? You lucky ones! We built in 1999/2000 in Friedrichsfehn (Karl-Bunje-Str.). 3m of peat had to be removed, 3.30m of fill sand was applied. I know the new residential area at Fuhrkenschen Grenzweg. It is being developed right now. Yes, there is less peat there. This is partly because it has already been drained. Depending on how much the new side street should be leveled to the height of Fuhrkenschen Grenzweg, more fill sand and topsoil will have to be applied there. Do yourselves a favor and don’t make the mistake we made: exchange the soil of the entire property. Otherwise, you will have to redo your garden completely after 10 years and again 10 years later. Due to surface drainage, the peat dries out and settles. For us, that is 50-60 cm, with 1.5m of peat still at least 30 cm.
Regarding costs: in 1999 we paid just under 17 DM per cubic meter for soil exchange (peat out, fill sand in) including compaction. Today of course it is more expensive. But you can negotiate with one or another contractor, for example have half invoiced and the other half not. Not only my observation: although the trip to and from the sand pit is considerably longer, contractors from the South Oldenburg area (Friesoythe, Cloppenburg, Bösel) are cheaper than the local companies.
And one more tip: Your street is currently being excavated and filled with fill sand. Talk to the contractor about exchanging the soil of your property. As a rule, contractors then offer a pretty good price. This comes about because they are on site with the excavator anyway and constantly transport earth and sand.
Haulage companies that come to mind immediately:
Henken, Friesoythe-Altenoythe
Becken, Bösel
Emil Hilgen Friedrichsfehn
Then I’ll already say welcome to Friedrichsfehn (See you at Aldi):
