European Commission Joint Research Centre 2 Simple Steps to Design Shear Walls The following pages o er a guide for the design loading or combined footing is used as an alternative to isolated footing. Start by laying out the outline of your foundation. Inside the strings dig a trench 18 wide and at least 2' deep (in colder climates you need to go down deeper to get below the frost line usually Around the trench build wooden concrete forms using 2 x 10 boards. More items Footing Design 10. Footing foundations, also known as spread, combined, or mat footings, transmit design loads into the underlying soil mass through direct contact with the soil immediately beneath the footing.
