Hello everyone,
we finally received our soil survey today, one day before the notary appointment for the land purchase.
As far as I can tell, 20 cm of topsoil must be removed (with a height difference of 17 cm in the affected area of the building plot), below which there are load-bearing glacial gravel soils, where care must be taken during excavation work to avoid softening.
The building can be founded on strip and individual footings or on a rigid reinforced concrete slab.
Regarding the water on the property, it was encountered as stagnant, layer, and seepage water, and due to the very low water permeability of the soil, it can locally and temporarily accumulate up to the height of the terrain, and in depressions even above that. However, it is not actual groundwater.
At the end of March, when the borehole samples were taken, water was also standing in the depressions on the property.
I am currently a bit concerned about the impermeable soil on the property. Not so much for the construction project itself, but also about what this means later for "our garden." We don't want water standing on the lawn or in the beds.
Can someone from you help me tonight or tomorrow morning with what this soil survey ultimately means for our property and us, or with which measures are best to counter the water standing on the property after longer periods of rain. Unfortunately, I can't reach a landscape gardener anymore tonight.
I would be very happy to receive replies!
Best regards - Vetti
