if your *site conditions* caused your walls to bulge and not break or leak then the superior system must be very good. there are a lot of factors that can act on a foundation. any lateral movement would be due to site conditions beyond what is considerered to act on a foundation unless your builder alerts the foundation company to extenuating circumstances.
superior walls are engineered to resist typical forces that act on a foundation. the engineering shows that the system will withstand the forces actiong on it better thatn a block foundation. if you have problems now, they would be worse if you used block. of course this is valid as long as the system was installed properly and there were no improper alterations made.
many building type companies do not respond to frantic claims that are obviously unfounded because anything you say can be yused against you in a court of law. the unfortuante fact is if y ou get any case into court, some amount will get paid no mattrer what.
