Terms
- Grade Beam - [1]
- Grade beam is the thickened outer edge of the slab foundation. [2]
- Spread footing - 'inverted T' actually holds the pressure on the soil. Grade beam functions like a beam - spanning 2 deep piles, not relying on soil underneath for support. [3]
- Grade beams connect column foundations together - [4]
- Slab foundations are used on flat lots [5]. Supported directly be ground.
Design
- Grade beam is min 8" wide, and depth is the length of span it supports [6]
- Compared to typical foundation, uses less concrete.
