PART 3 EXECUTION
3.1 VERIFICATION OF CONDITIONS
Before starting the work, verify that surfaces to be waterproofed are in satisfactory condition. Notify the
Contracting Officer of defects or conditions that will prevent a satisfactory application. Do not start application
until defects and conditions have been corrected.
3.2 SURFACE PREPARATION
NOTE: A paragraph should be added to Section 03 31 00.00 10, CAST-IN-PLACE
STRUCTURAL CONCRETE, Section 03 30 00 CAST-IN-PLACE CONCRETE, to the effect
that curing compound containing wax or oil should be removed prior to application
of waterproofing.
Ensure surfaces to be treated are clean, dry, smooth, and free from deleterious materials and projections. [Thoroughly
wet holes, joints, cracks, and voids in [masonry] [concrete] with water and fill with Portland cement mortar,
strike flush, and permit to dry.] Cut off high spots or grind smooth. Finish top surfaces of projecting masonry
or concrete ledges below grade, except footings, to a steep bevel with Portland cement mortar. Sweep surfaces
to be covered before applying waterproofing to remove dust and foreign matter. Cure concrete by a method compatible
with the waterproofing system.
3.3 APPLICATION
NOTE: Delete requirements for cant strips if cant strips are not required.
Follow manufacturer's printed installation instructions. [Where indicated, mop continuous cant strips in place
at vertical and horizontal corners before installing the waterproofing membrane. Do not use untreated wood or
wood fiber cants.] When using solvent welding liquid, avoid prolonged contact with skin and breathing of vapor.
[Provide adequate ventilation.] Carry waterproofing of horizontal surfaces up abutting vertical surfaces as indicated
and adhere solid to the substrate. Avoid wrinkles and buckles in applying membrane and joint reinforcement.
a. Non-Self-Adhering Membrane: Unroll membrane and allow to remain flat for at least one-half
hour before application. Apply an asphalt concrete primer prior to application of asphaltic
adhesive. Where solvent adhesive is applied, allow major portion of solvent to evaporate so
that bonding adhesive does not stick to a dry finger touching it. Apply elastomeric waterproofing
membrane in a full bed of adhesive at a uniform coverage rate in accordance with the recommendations
in the membrane manufacturer's printed instructions. [Where membrane on horizontal surfaces
are to receive concrete fill, apply adhesive in 100 mm 4 inch wide strips at 600 mm 2 feet on
center.] Pull membrane tight without stretching. As soon as adhesive is fully set and dry,
recheck lap splices. Where openings or fishmouths appear, reseal and reroll lap splices.
b. Self-Adhering Membrane: Apply composite, self-adhering membrane on surfaces primed at a
uniform coverage rate in accordance with membrane manufacturer's printed instructions. Remove
release sheet and apply with tacky surface in contact with dried primer.
c. Protection: Protect membrane over horizontal surfaces from abnormal traffic during installation.
Use only equipment with rubber tires. Provide walkway protection where heavy traffic from other
trades is expected. Do not store material on membrane.
3.3.1 Butyl Rubber
Lap sheets at sides and ends a minimum of 150 mm 6 inches over the preceding sheet. Apply lap splicing cement
over entire 150 mm 6 inches splice area prior to application of sealant. Sealant shall be continious along the
entire length of the splice. Maintain a continuous bead of sealant at all membrane splices or as required by
the manufacturer. When membrane will be below water table, provide a tongue and groove cemented splice a minimum
of 150 mm 6 inches with factory made heat vulcanized seam not less than 50 mm 2 inches or as required by the
manufacturer.
3.3.2 Thermoplastic Membrane (PVC)
Deck shall be clean, smooth and dry without surface irregularities. Consult with membrane manufacturer prior
to grid application. Install 30.48 cm 12 inches wide sub-membrane containment grid as required by manufacturer.
Provide and install the containment grid at intervals across the width and length of the substrate, at the base
of all transitions, walls, curbs, penetrations, and at the perimeter of each deck/substrate section. Fully adhere
strips to the deck in a full bedding of two-part urethane adhesive medium. Adjacent sheets shall be welded in
accordance with manufacturer's instructions. All side and end lap joints shall be hot-air welded. Lap area
shall be a minimum of 7.62 cm 3 inch wide when machine welding, and a minimum of 10.16 cm 4 inch wide when hand
welding but not less than recommended by the manufacturer. Overlaps shall be with the flow of water.
3.4 Composite, Self-Adhering Membrane
Lap sheets at edges and ends a minimum of 65 mm 2 1/2 inches over the preceding sheet. All side laps shall be
minimum 65 mm 2 1/2 inchesand end laps shall be 5 inches, 127 mm. Laps shall be self adhesive, mastic as per
manufacturer's recommendation. Roll or firmly press to adhere membrane to substrate. Cover corners and joints
with two layers of reinforcement by first applying a 300 mm 12 inch width of membrane centered along the axis.
Flash drains and projections with a second ply of membrane for a distance of 150 mm 6 inches from the drain
or projection. Finish exposed, terminated edges of membrane on horizontal or vertical surfaces with a trowelled
bead of mastic. Apply mastic around edges of membrane, and drains and projections. Apply mastic at end of each
work day.
3.5 FLASHING
Flash penetrations through membrane. Ensure that where reinforcing bars penetrate a waterproofing membrane,
each of those penetrations be sealed with the appropriate sealant or mastic flashing component. Embed elastomeric
membrane in a heavy coat of adhesive, except for self-adhering membrane. Continuous metal reglets shall be installed,
horizontally on footing and vertically on intersecting and connecting walls, and as specified in Section
07 57 13 FLASHING AND SHEET METAL. Metal reglets shall receive exposed edges of membrane waterproofing. Secure
membrane into reglets by lead wedges and fill with cement as recommended by manufacturer of waterproofing materials.
Counterflash upper edge of membrane waterproofing and protective covering as specified in Section 07 57 13 FLASHING
AND SHEET METAL.
3.6 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.
3.7 PROTECTIVE COVERING
After installation has been inspected and approved by the Contracting 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 manufacturer of protection board. Cover horizontal
membrane waterproofing 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 subsequent construction.
