Strip foundation Designing Buildings Wiki

Wide strip foundations may be required where the soil is soft or of a low bearing capacity, so as to spread the load over a larger area. Wide strip foundations will typically require reinforcement. Where there are higher localised loads, such as columns, pad foundations may be used. See pad foundations for more information.
