Types of foundation. 1.       Concrete strip FOUNDATION. ü   They are frequently used. ü   They consist of continuous mass concrete strips poured in the bottom of the trenches. ü   These foundations supports load bearing walls which are centered on the concrete strips to spread the pressure from the walls, roofs, and other floor loads evenly. ü   The concrete strip is usually a uniform width and depth. ü   The foundation must be wide and deep enough to avoid soil movement that could cause instability ü   Depending on soil conditions, the max depth may be 900mm. ü   The concrete must be at least as thick as its projection from the base of the wall. ü   This ensures that the pressure of the building loads are distributed in the concrete at an angle of 45°. 2.       Deep strip FD The deep strip foundation is a variation of strip foundations.
