Cracks and cracks

For the last 2 weeks the floor is being prepared for the eventual installation of the bamboo flooring. In a couple of previous postings I have been showing pictures of new concrete being poured to even out the overly uneven region, debris being scraped from the removed previous floorings and there were tons of those including 2 layers from previous installations of the original laminate flooring and later on, tiles, carpets etc.
Well, so far it's just been a routine leveling and standard preparation, and then I was told about all the cracks and their undesirable effect of cracking the adjoining windows. Apparently the buckling of the foundation has a lot to do with the high ground water level underneath the foundation which most likely has been seeping through the bare ground right next to the house. Throughout the house the cracks are most apparent next to exterior regions that only have bare earth with downspouts.

Look at the crack on the window and the soil next to it.

Again cracks inside and outside.

To fix this problem Peter suggested to dig trenches to lead water from all downspouts away from the house. Basically this means that renovation will have to extend to the outside.... Apparently this is a rather common problem with Eichler houses. Once again, the pros and cons of owning a classic mid century modern tract house.
