Sandy.

Aquaguard was able to drive steel beams into the soil and lift the corner to secure it.

Or if at some point someone textured over wallpaper and painted it.Texas has expansive clay soil.

What do you do generally do in poor soil conditions:Crawlspace or Structural basement? 

This could cause problems down the road with soil erosion near the foundation and that would be bad.

Thank you so much Sandy.

I would think if you used all glue and not mechanical fasteners that over time the moisture migrating through the concrete from the outside soils would cause the glue to eventually delaminate.

Thank you Sandy.

Maybe put soil on everything so the broken cement surface and the dirt area is covered with the new soil.

A single septic can costs anywhere between $4,000 and the commercial ones can go up to $25,000 or more.Your soil is very important to the type of septic system that will be allowed.
