Sea level pressure under a dome on Mars produces a lifting force of 27 tons per square meter. That's the equivalent of 10 meters of solid rock. If your dome is lighter than that, it will be trying to pop off the foundation and has to be either tied or weighted down.

Foundation, will be critical, what if the pressure was kept to around 10000 ft.

No. Lightweight domes as is often shown in artist's illustrations are dumb. Make the domes heavy enough to stay put on the foundation and they double as radiation protection.
