11oz. tubes.
PART 3 - EXECUTION
3.1 EXAMINATION
A. Installing Contractor shall examine substrates, areas, and conditions for compliance
with requirements and other conditions affecting performance and submit a report in
writing to the General Contractor or Architect that all substrates, areas, and
conditions are in conformance with the manufacturer’s requirements for the
installation of the waterproof membrane.
1. Do not proceed with installation until after the minimum concrete curing period
recommended by waterproofing manufacturer.
2. Verify that substrate is visibly dry and free of moisture. Test for capillary
moisture by plastic sheet method according to ASTM D 4263.

3. Notify Architect in writing of anticipated problems using waterproofing over
substrate.
4. Proceed with installation only after unsatisfactory conditions have been
corrected.
3.2 SURFACE PREPARATION
A. Clean, prepare, and treat substrates according to manufacturer's written instructions.
Provide clean, dust-free, and dry substrates for waterproofing application.
B. Mask off adjoining surfaces not receiving waterproofing to prevent spillage and
overspray affecting other construction.
C. Remove grease, oil, bitumen, form-release agents, paints, curing compounds, and
other penetrating contaminants or film-forming coatings from concrete.
D. Remove fins, ridges, mortar, and other projections and fill honeycomb, aggregate
pockets, holes, and other voids.
E. Prepare, fill, prime, and treat joints and cracks in substrates. Remove dust and dirt
from joints and cracks according to ASTM D 4258.
F. Prepare, treat, and seal vertical and horizontal surfaces at terminations and
penetrations through waterproofing and at drains and protrusions.
3.3 FULLY ADHERED SHEET INSTALLATION
A. Install fully adhered sheets over entire area to receive neoprene sheet flashing
according to manufacturer's written instructions and recommendations in
ASTM D 5843.
B. Apply bonding adhesive to substrates at a rate of one gallon per 125 square feet and
allow to partially dry to the touch. The bonding adhesive should be tacky, but no
adhesive should transfer to the finger when pressed into it.
C. Remove poly film from neoprene sheet and cut roll to workable lengths for
the application of the bonding adhesive.
B. Apply bonding adhesive to neoprene sheet flashing and firmly adhere sheets to
substrates. Start application of neoprene sheet flashing by placing it 4” onto
horizontal deck, extend sheet across 2” structural expansion joint and extend it up 6”
onto vertical substrate. Accurately align sheets and maintain uniform end lap of 6”
minimum. Install termination bar & sealant at the top of the neoprene sheet flashing
in accordance with manufacturer’s recommendations.
C. Repair tears, voids, and lapped seams in waterproofing not complying with
requirements. Slit and flatten fish mouths and blisters. Patch with neoprene sheet
flashing extending beyond repaired areas in all directions.
D. Protection: Protect building from damage resulting from spillage and dropping
materials. Do not allow materials to enter and clog drains and associated piping.

Prevent spillage and migration onto other surfaces of the Work by masking or
otherwise protecting such work.
3.4 FIELD QUALITY CONTROL
A. Test each completed installation area for leaks, according to recommendations in
ASTM D 5957, after completing waterproofing but before overlying construction is
placed. Prohibit all traffic on test area until area is protected. Perform tests only when
temperatures remain above freezing for the duration of the test.
1. After testing, repair leaks, repeat tests, and make further repairs
until waterproofing installation is watertight.
2. Inspect all seams within the test area.
B. Engage an independent testing agency to observe leak testing and examine
for evidence of leaks during flood testing.
1. Provide General Contractor or Architect with a written report documenting
the test date, weather conditions, location of the test area on a drawing along
with appropriate photographs, surveillance results, and test results including
all leak remediation recommendations.
3.5 PROTECTION AND CLEANING
