If there is no hydrostatic pressure expected
1813.3 Damp proofing required
1813.3.2 Walls: ....All holes and recess from removal of form ties to be filled with bituminous material or other approved methods or materials. Unit masonry walls shall be parged on the exterior surface below ground level with not less than 3/8 inch of portland cement.
1813.3.2.2. Wall Damproofing materials: Dampproofing shall consist of bituminous material, 3 pounds per square yard of acrylic modified cement, 1/8 inch of surface bonding mortar complying with ASTM C887 listed in Chapter 35, any of te materials for waterproofing listed in section 1813. 4.2.2, or other approved materials...

Where there is expected possible hydrostatic pressure
1813.4 Waterproofing required
1813.4.22 Wall waterproofing materials: .....two ply hot mopped felts, not less than 6 mil (.006 ") PVC, 40 mil (.040") polymer modified asphalt, 6 mil polyethylene or other approved methods of bridging non-structural gaps.

My takaway from all that codespeak is either some sort of 3/8" thick cement parging or an asphalt type coating will work as long as the ground water level doesn't get too high or put too much pressure on that wall.

From some of the other books, if back filling with gravel, at the bottom have the soil or the membrane if using one direct the water way from the wall.
