Remember that way Kamui's "intangibility" works is that it sends part of your body to Kamui's Dimension. For example, if your opponent strikes your neck with sword horizontally, with Kamui you can send the part of neck that blade would normally hit to Kamui's Dimension. The rest of your body would still exist in current dimension, thus you wouldn't fall through the ground.
