NOTE: This guide specification should not be used to specify waterproofing
of structures subject to hydrostatic pressure. It includes the fluid-applied
membrane, protection board, drainage layer, and insulation. It does not include
structural deck, protection slab, or wearing course; these elements influence
performance of the waterproofing system. See MIL-HDBK-1001/5 for design recommendations.
Technical Reference: ASTM C 898, "High Solids Content, Cold Liquid-Applied
Elastomeric Waterproofing Membrane with Separate Wearing Course." This document
contains guidelines for design of the waterproofing system, and may be used
as a source of supplementary information.
1. Slope: Provide slope toward drains (after deflections due to applied load
and creep) of not less than one percent 10 millimeters (mm) per meter 1/8 inch
per foot.
2. Wall Flashing: Extend wall flashing to at least 100 mm 4 inches above wearing
surface and higher where exposure is more severe. If top of flashing is recessed
under a concrete wall, counterflashing is not necessary. Metal counterflashing
is necessary at masonry wall intersections. Flash right-angle intersection
of deck and wall with an elastomeric sheet.

PART 3 EXECUTION
3.1 PREPARATION
Coordinate work with that of other trades to ensure that components to be incorporated into the waterproofing
system are available when needed. Inspect and approve surfaces immediately before application of waterproofing
materials. Remove laitance, loose aggregate, sharp projections, grease, oil, dirt, curing compounds, and other
contaminants which could adversely affect the complete bonding of the fluid-applied membrane to the concrete
surface.
3.1.1 Flashings
Make penetrations through sleeves in concrete slab watertight before application of waterproofing. After flashing
is completed, cover elastomeric sheet with fluid-applied waterproofing during waterproofing application.
3.1.1.1 Drains
Make drain flanges flush with surface of structural slab. Apply a full elastomeric sheet around the drain, with
edges fully adhered to drain flange and to structural slab. Do not adhere elastomeric sheet over joint between
drain and concrete slab. Do not plug drainage or weep holes. Cover elastomeric sheet with fluid-applied waterproofing
during waterproofing application. Lap elastomeric sheet a minimum of 100 mm 4 inches onto concrete slab.
3.1.1.2 Penetrations and Projections
Flash penetrations and projections through structural slab with an elastomeric sheet adhered to the concrete
slab and the penetration. Leave elastomeric sheet unadhered for 25 mm one inch over joint between penetration
and concrete slab. Adhere elastomeric sheet a minimum of 100 mm 4 inches onto horizontal deck.
3.1.1.3 Walls and Vertical Surfaces
Flash wall intersections which are not of monolithic pour or constructed with reinforced concrete joints with
an elastomeric sheet adhered to both vertical wall surfaces and concrete slab. Flash intersections which are
monolithically poured or constructed with reinforced concrete joints with either an elastomeric sheet or a vertical
grade of fluid-applied waterproofing adhered to vertical wall surfaces and concrete slab. Leave sheet unadhered
for a distance of 25 mm one inch from the corner on both vertical and horizontal surfaces.
3.1.2 Cracks and Joints
Prepare visible cracks and joints in substrate to receive fluid-applied waterproofing membrane by placing a bond
breaker and an elastomeric slip sheet between membrane and substrate. Cracks that show movement shall receive
a 50 mm 2 inch bond breaker followed by an elastomeric sheet adhered to the deck. Nonmoving cracks shall be
double coated with fluid-applied waterproofing.
3.1.3 Priming
Prime surfaces to receive fluid-applied waterproofing membrane. Apply primer as required by membrane manufacturer's
printed instructions.
3.2 SPECIAL PRECAUTIONS
Protect waterproofing materials during transport and application. Do not dilute primers and other materials,
unless specifically recommended by materials manufacturer. Keep containers closed except when removing contents.
Do not mix remains of unlike materials. Thoroughly remove residual materials before using application equipment
for mixing and transporting materials. Do not permit equipment on the project site that has residue of materials
used on previous projects. Use cleaners only for cleaning, not for thinning primers or membrane materials.
Ensure that workers and others who walk on cured membrane wear clean, soft-soled shoes to avoid damaging the
waterproofing materials.
3.3 APPLICATION
Over primed surfaces, provide a uniform, wet, monolithic coating of fluid-applied membrane, 1.5 mm 60 mils thick,
plus or minus 0.125 mm 5 mils by following manufacturer's printed instructions. Apply material by trowel, squeegee,
roller, brush, spray apparatus, or other method recommended by membrane manufacturer. Check wet film thickness
as specified in paragraph entitled "Film Thickness" and adjust application rate as necessary to provide a uniform
coating of the thickness specified. Where possible, mark off surface to be coated in equal units to facilitate
proper coverage. At expansion joints, control joints, prepared cracks, flashing, and terminations, carry membrane
over preformed elastomeric sheet in a uniform 1.5 mm 60 mil thick, plus or minus 0.125 mm 5 mils, wet thickness
to provide a monolithic coating. If membrane cures before next application, wipe previously applied membrane
with a solvent to remove dirt and dust that could inhibit adhesion of overlapping membrane coat. Use solvent
recommended by the membrane manufacturer, as approved.
3.3.1 Work Sequence
Perform work so that protection board is installed prior to using the waterproofed surface. Do not permanently
install protection board until the membrane has passed the flood test specified under paragraph entitled "Flood
Test." Move material storage areas as work progresses to prevent abuse of membrane and overloading of structural
deck.
3.3.2 Protection Board
Protect fluid-applied membrane by placing protection board over membrane at a time recommended by the membrane
manufacturer. Protect membrane application when protection board is not placed immediately. Butt protection
boards together and do not overlap.
3.3.3 Drainage Course
Place drainage course where shown after flood tests are completed and concrete protection slab or wearing course
is ready to be installed.
3.3.4 Insulation
Place insulation of thickness indicated, on top of drainage course just prior to placement of concrete protection
slab.
3.4 FIELD QUALITY CONTROL
3.4.1 Moisture Test
Prior to application of fluid-applied waterproofing, measure moisture content of substrate with a moisture meter
in the presence of the Contracting Officer. An acceptable device is the Delmhorst Moisture Meter, Model BD7/2E/CS,
Type 21 E. Similar meters by other manufacturers, which are suitable for the purpose, may be used as approved
by the Contracting Officer. Do not begin application until meter reading indicates "dry" range.
3.4.2 Film Thickness
Measure wet film thickness every 10 square meters 100 square feetduring application by placing flat metal plates
on the substrate or using a mil-thickness gage especially manufactured for the purpose.
3.4.3 Flood Test
After application and curing is complete, plug drains and fill waterproofed area with water to a depth of 50
mm 2 inches. A minimum 48 hour cure time, or longer cure time if recommended by the membrane manufacturer, shall
be required prior to flood testing. Allow water to stand 24 hours. Test watertightness by measuring water level
at beginning and end of the 24 hour period. If water level falls, drain water, allow installation to dry, and
inspect. Make repairs or replace as required and repeat the test. Work shall not proceed before approval of
repairs or replacement.
