Floating foundations are typically effective where weak soil conditions exist and it is desireable to spread the pressure of the structure on the soil over a larger area.
What are the benefits of using floating foundations in construction projects?
deep foundations may be more expensive than a floating foundation. Employing the services of a geotechnical engineer would be very helpful.
expansive soil (that expands and lifts buildings when it gets wet and shrinks when it dries), a floating foundation can help.
Deep foundations are also effective for these conditions, provided there is stronger soil or solid rock at a deeper depth.
helpful for preventing excessive differential foundation settlement, which can cause cracks and other problems with a structure.
