Every time you walk across the threshold of your house or apartment you step with confidence knowing from the history of your experience that the decking is rigid and stable. Most of us don’t think twice about what is under the framework that gives us that confidence – the foundation. To be sure, we know that it’s there but we don’t often worry about it because it’s just there. If we purchased our house we no doubt inspected or paid for someone to inspect the foundations closely and so assure us of its correctness. We purchased the house with confidence because we knew there were no foundation liabilities.
