ᐅ Geotextile Fabric in Foundations – Incorrect Durability Class (DC)

Hello everyone,

I have another question.

My foundation contractor used GRK 2 geotextile as a separation layer during the foundation work, which I noticed afterwards.

However, the soil report specifies at least GRK 3. Is this a problem? Or should I just add an additional layer of GRK 3 geotextile?

Currently, there is a layer of gravel above the geotextile. At least another 1.5m (5 feet) of gravel will be added on top.

Thanks in advance!
