PRE-INSTALLATION CONFERENCE AND TRIAL MIXES
Convene pre-installation conference at the Contractor's direction prior to commencing
work to review methods and sequence of installation. The meeting shall include the
Engineer, Contractor and/or Subcontractor, Manufacturer's Representative. Requirement
for manufacturer’s representative may be waived if Contractor provides sufficient
evidence that Producer and Finisher have adequate experience with admixture required.
Trial mixes shall be carried out with proposed mix design to insure that mix meets all
requirements set forth in the specification, prior to actual installation of concrete.
Provide 10-year manufacturer’s limited material warranty for the crystalline
waterproofing powder admixture.

Crystalline Integral Waterproofing Admixture: Permeability-reducing admixture for
hydrostatic conditions (PRAH) as defined by ACI 212.3R-10, Chapter 15. Powder
waterproofing admixture with the following characteristics:
2. Aggregate state:
Powder – non corrosive.
3. Compressive Strength:(ASTM C-39)Treated concrete must have equal or higher

PART 3 - EXECUTION
Assure that concrete mix design and proposed material are in compliance with
Dosage rate of the waterproofing admixture shall be 0.8% - 1.0% of Portland
cement content per yd3 (m3).
The water/cement ratio (w/c) of the concrete mix shall be as specified, but not
Depending on the geographical location and brand of Portland cement the set time of
the concrete may vary by delayed or accelerated set time. The amount of delayed or
accelerated set time depends upon the concrete mix design, concrete additives,
temperature of the concrete and climatic conditions. The compressive strength of the
concrete mix with the waterproofing admixture may also be higher than plain concrete.
03 30 00-3
Assure that trial mixes and material testing has been carried out prior to starting
concrete work. Determine workability, setting times, slump, air-content and strength
development. Adjust retarding, accelerating and plasticizing admixtures accordingly.
Verify existing conditions before starting work.
Verify that the joints are treated according to the requirements of the waterproofing
Comply with manufacturer’s product data and installation instructions.
Crystalline waterproofing admixture shall be added to the concrete at the time of
batching at a concrete plant or to the finished mix in the ready mix truck at the job site.
The sequence of procedure for addition will vary according to the type of batch plant
operation, equipment and distance from the job site.
Do not add bulk (bag) dry powder crystalline waterproofing admix to wet concrete mix.
This may cause clumping of the admix and uniform dispersion cannot be guaranteed.
Mix with water first, before adding to wet concrete.
At batching plant:
Add 4 gal. (15 L) potable water per 50 lbs. (22.7 kg) powder to the wet, empty
turning drum of the ready-mix truck.
Add specified amount of powder crystalline waterproofing admix to turning
drum and mix the powder with the water for minimum 3 minutes to a thin
slurry. Assure homogenous mixing. Alternatively pre-mix the powder with water
to a slurry in a plastic pail and add to the wet concrete mix in the drum of the
Drive the ready-mix truck under the batch plant and add/drop the specified
amount of concrete mix into the ready-mix truck. Take into account the amount
of water contained in the crystalline slurry mix.
Mix at least 5 minutes to assure homogenous distribution of the crystalline
slurry mix within the concrete.
Carry out slump and air-content quality control at job site before pouring of
concrete. Prepare cylinders for concrete strength control.
Ready-mix truck at job site:
Mix the crystalline powder in a plastic pail with potable water to a thin slurry
consistency. I.e. 50 lbs. (22.7 kg) powder to 3 gal. (12 L) water. Mix for at
least 3 minutes.
Add the crystalline slurry to the wet concrete mix in the turning drum of the

Precast batch plant – pan type mixer:
Add the crystalline powder waterproofing to the sand and aggregate, then mix
thoroughly for 3 – 5 minutes before adding the Portland cement and water.
