FIELD QUALITY CONTROL
Notify the Contracting Officer one day prior to date of performing tests.
Before concealment, cover elastomeric waterproofing on horizontal surfaces
over finished spaces with [75] [100] mm [3] [4] inches of ponded water for
24 hours. Do not add water after start of 24 hour period. Carefully
measure water level at beginning and end of 24 hour period. If water level
falls, remove water and inspect waterproofing membrane. Make repairs or
replacement as directed, and repeat test. Do not proceed with work that
conceals membrane waterproofing before receiving approval and acceptance of
Contracting Officer.

Officer, apply a protective covering to the membrane waterproofing prior to
backfilling. Protect vertical membrane waterproofing with a 13 mm 1/2 inch
minimum thickness of asphalt plank; 13 mm 1/2 inchminimum thickness of
fiberboard; or 3 mm 1/8 inch minimum thickness of compatible
water-resistant bitumen type protection board with edges abutting adjacent
edges and exposed surfaces covered by a taping system recommended by

with similar protection board and Portland cement mortar not less than 20 mm
3/4 inch thick; place uniformly and allow to set before installing
