Quote from: John Raabe on August 16, 2014, 04:40:15 PMInteresting and I agree, pier foundations and bracing for sideward forces should be reviewed by a local engineer - most especially when building in poorly drained soil, on steep slopes or (even worse) on fill. But just advising a standard concrete foundation over a pier system may not help.Understanding the character of the soil and the building site before committing to a build is key. Frost heave in expansive soils can be very persuasive, no matter what the foundation system used. If there is any question about the stability of the soil, it is worth a visit from a soils (geotech) engineer. There have and will always be houses that are built in soil that should not have buildings on them. Building on such sites can be expensive and is best avoided. This is a battle nature usually wins.What are the soil conditions at the third foundation house and what are the engineers suggesting for a solution?
