SECTION 1828 - OTHER DAMPPROOFING AND
WATERPROOFING REQUIREMENTS
1828.1 Placement of Backfill.
The excavation outside the foundation
shall be backfilled with soil which is free of organic material,
construction debris and large rocks. The backfill shall be placed
in lifts and compacted in a manner which does not damage the waterproofing
or dampproofing material or structurally damage the wall.
1828.2 Site Grading. The

away from the building at not less than 1 unit vertical in 12
units horizontal (8.3% slope) for a minimum distance of 6 feet
(1829 mm) measured perpendicular to the face of the wall or an
approved alternate method of diverting water away from the foundation
shall be used. Consideration shall be given to possible additional
settlement of the backfill when establishing final ground level
adjacent to the foundation.
1828.3 Erosion Protection. Where
water impacts the ground from the edge of the roof, downspout,
scupper, valley, or other rainwater collection or diversion device,
provisions shall be used to prevent soil erosion and direct the
