PROCEDURES and edit the following list to reflect only the submittals required
for the project. Submittals should be kept to the minimum required for adequate
quality control.
A “G” following a submittal item indicates that the submittal requires Government
approval. Some submittals are already marked with a “G”. Only delete an existing
“G” if the submittal item is not complex and can be reviewed through the Contractor’s
Quality Control system. Only add a “G” if the submittal is sufficiently important
or complex in context of the project.
For submittals requiring Government approval on Army projects, a code of up
to three characters within the submittal tags may be used following the "G"
designation to indicate the approving authority. Codes for Army projects using
the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO"
for District Office (Engineering Division or other organization in the District
Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project
Office. Codes following the "G" typically are not used for Navy, Air Force,
and NASA projects.
Choose the first bracketed item for Navy, Air Force and NASA projects, or choose
the second bracketed item for Army projects.
Government approval is required for submittals with a "G" designation; submittals not having a "G" designation
are for [Contractor Quality Control approval.] [information only. When used, a designation following the "G"
designation identifies the office that will review the submittal for the Government.] The following shall be

PART 3 EXECUTION
3.1 INSPECTION OF SURFACES
Before starting the work, inspect all surfaces to be waterproofed to determine if in satisfactory condition.
Check the location and setting of all embedded items. Place backing and blocking and perimeter framing for recessed
items as required by the various trades on the project. Complete conduit, piping, and other required rough-in.
Notify the Contracting Officer of serious defects or conditions that will prevent satisfactory application.
Start application after such defects and conditions have been corrected.
3.2 PREPARATION OF SURFACES
NOTE: Concrete surfaces to which membrane waterproofing is to be applied should
be moist cured. Waterproofing should not be applied to surfaces which have
been cured with membrane-forming compounds or other coatings which may reduce
the bonding of the waterproofing to the concrete. Masonry over which waterproofing
is to be applied should be specified to have flush mortar joints.
Surfaces to be treated shall be clean and dry, smooth and free from deleterious and excess materials and projections.
[Masonry surfaces shall be free of oil, grease, dirt, laitance, loose and broken material, frost, debris and
other contaminants.] [Concrete surfaces shall be properly cured, free of release agents, oil, grease, dirt,
laitance, loose material, frost, debris and other contaminants. Thoroughly wet holes, joints, cracks, and voids
in concrete with water, and then carefully fill with portland cement mortar, strike flush, and permit to dry.]
Cut off or grind smooth high spots. [Mortar joints in masonry walls shall be flush and free of extraneous mortar.]
[Metal surfaces shall be dry and be free of rust, scale, loose paint, oil, grease, dirt, frost and debris.]
Give surfaces to receive asphalt membrane waterproofing a priming coat of asphalt primer. Apply priming coat
at a rate not less than 4 liters per 10 square meters one gallon per 100 square feet, covering the entire surface
to be waterproofed. Allow primer to dry before applying waterproofing.

migration of asphalt onto other work. [Drains and conductors shall be protected from clogging with asphalt.]
3.3.2.1 Fired Kettles
Melt kettles for bitumen shall not be closer than 8 meters 25 feet to buildings or combustible materials. Provide
minimum of two 9 kilogram 20 pound ABC all-purpose type extinguishers at melting kettle and area of hot material
application. Equip kettles with automatic thermostatic control capable of maintaining asphalt temperature.

agitation to ensure controlled uniform temperature throughout contents to prevent spot heating. Do not heat
contents above flash point.ext
3.3.2.2 Heating and Application of Bitumen Coatings

of the specified temperature. Provide an accurate and clearly readable thermometer on all kettles. [Bulk liquid
asphalt may be heated using the heating equipment in the transport tanker vehicle or transferred to kettles and
heated as specified for solid bitumen.] Heat bitumen to flow freely but not above 190 degrees C 375 degrees F
. Apply bitumen over the primer, between each ply and as a top coating at the rate of not less than 10 kilograms
20 pounds of asphalt per 10 square meters 100 square feet of surface.
3.3.3 Membrane Waterproofing
NOTE: Where waterproofing must be applied to concrete or masonry walls in waterlogged
soils or where settlement is likely to occur, use fabric type instead of felt
type. Where rough masonry walls must be waterproofed, unless such walls can
be made reasonably smooth with parging of cement mortar, only fabric type should
be specified. To determine number of plies of membrane for vertical application

flashing to the outside edge of the footing, and turn the flashing down 100 mm 4 inches. Continue the flashing
through the joint to the inside of the walls and lap the flashing into the waterproofing membrane under the slab.
Protect the flashing until it is lapped by the waterproofing membranes for the subsurface floor slabs and foundation
walls. The flashing membrane shall be made up of the same number and type materials as the waterproofing membrane
or a thermoplastic material compatible with the waterproofing materials, as recommended by the manufacturer.
3.3.6 Flashing Flanges

asphalt manufacturer's plant.
Notify the Contracting Officer one working day prior to the delivery date of asphalt. Take a minimum of one
quart sample of each shipment of bulk liquid asphalt when the shipment arrives at the construction site. Obtain
samples in the presence of the Contracting Officer using clean one-quart, friction-lid cans. Label samples to
indicate project contract number, location where used on project, and date and time of arrival of shipment from
which sample is taken. Give samples to the Contracting Officer for safekeeping until picked up by the testing
laboratory. The Contractor shall pay for the testing of the bulk liquid asphalt. Samples tested which are found
not to be in conformance with specification requirements will constitute grounds for rejection. Remove and replace
with new materials all waterproofing installed with asphalt from which the nonconforming samples were taken.
[3.4.2 Test of Membrane Waterproofing
Prior to concealment, plug the drain and cover membrane waterproofing on horizontal surfaces over finished spaces
with [75] [100] mm [3] [4] inches of ponded water for 24 hours to test watertightness. Make careful measurement
of the water level at the beginning and end of the 24-hour period. If water level falls, drain the water, and
thoroughly dry and inspect the waterproofing membrane. Make repairs or replacement, as directed, and repeat
test. Work which conceals membrane waterproofing shall not proceed before approval of test results.
]3.5 PROTECTIVE COVERING
3.5.1 Vertical Surfaces
Protect membrane waterproofing against which backfill is to be placed by providing protective covering pressed
into the final mopping while the mopping of bitumen is still hot. Butt edges of protection board against adjacent
edges of protection boards. Cover exposed surfaces with a coating of bitumen. Where surfaced fiberboard or
mineral fiberboard is used, place surface side facing outward. Fit board around pipes and projections so as
to cover the entire surface of the membrane waterproofing.
3.5.2 Horizontal Surfaces
