N.J. Admin. Code § 19:6-2.29 - Foundation walls

(a) Concrete foundation walls shall be designed in accordance with the requirements of this subchapter relating to bearing or retaining walls. The equivalent unbraced height of a wall supported by lateral soil pressure may be determined by a recognized method of elastic analysis. Alternatively, such a wall may be assumed to be laterally braced at intervals as follows:

1. Where fill is placed against both faces of the walls: the full height of the wall or eight times the thickness, whichever is the lesser value.

2. Where both faces of the wall are not in contact with the soil: the height of the unbraced section of the wall or eight times the thickness of the wall, whichever is greater, but not more than the full height of the wall.

(b) Masonry foundation walls shall conform to the requirements of this subchapter and the following:

1. Types: Masonary foundation walls may be of plain or reinforced masonry and shall be of solid units, except that load bearing hollow units shall be permitted for support of one and two-story buildings.

2. Wall thickness: Foundation walls of masonry shall be designed and constructed in accordance with the requirements of this subchapter supplemented by the provisions of this section relating to the unbraced height. The thickness shall be at least six inches.
