Hello to the forum,
my wife and I want to build a house. We have already chosen and reserved a plot of land. The plot is already filled and compacted with fill sand. Since it is a new development area, the developing construction company was also able to provide a soil report for the plot.
I have 2 questions regarding this:
1. The report states the following: The allowable bearing pressure was calculated for a strip foundation with b = 0.50 m and t = 0.80 m with σzul = 160 kN/m².
2. Groundwater During the geotechnical investigations, groundwater was encountered at about 1.00 m depth below the former ground surface level of the plot. This corresponds to a depth of about 7.80 m NN. According to the terrain elevation carried out, groundwater presence must be expected from about 1.90 m below the ground surface of the plot. Fluctuations in the water level cannot be excluded.
Regarding 1) I read in the general construction descriptions of the developers that a soil bearing capacity of 200 kN/m² is specified. Does the above-mentioned value therefore not suffice so that additional measures must be taken?
Regarding 2) I am not sure, but do the determined values possibly indicate that a "moist" soil/subsoil must be expected? We are not planning a basement, but still?
How do you interpret both points from the report? My wife and I would be very happy about feedback and tips.
