1.03 SYSTEM DESCRIPTION
A. Cementitious Crystalline Waterproofing (Dry Shake): Blend of portland cement, active proprietary chemicals and aggregate that has been graded and crushed to particle sizes suitable for concrete floors. When applied as a dry shake to freshly poured concrete slabs, the active chemicals cause a catalytic reaction which generates a non-soluble crystalline formation of dendritic fibers within the pores and capillary tracts of concrete. This process causes concrete to become permanently sealed against the penetration of liquids from any direction. For areas where increased abrasion resistance is required, the dry shake waterproofing shall contain a proprietary aggregate hardener.
1.04 SYSTEM PERFORMANCE REQUIREMENTS
A. Testing Requirements:
Crystalline waterproofing system shall be tested in
accordance with the following standards and conditions,
and the testing results shall meet or exceed the performance
requirements as specified herein.
B. Independent Laboratory:
Testing shall be performed by an independent laboratory
meeting the requirements of ASTM E 329-90 and certified
by the United States Bureau of Standards. Testing
laboratory shall obtain all concrete samples and waterproofing
product samples.
C. Crystalline Penetration:
Crystallizing capability of waterproofing material
shall be evidenced by independent SEM (Scanning Electron
Microscope) photographs documenting penetration of
crystal-forming waterproofing material to a depth
of 2 inches (50 mm).
D. Permeability:
Independent testing shall be performed according to
U.S. Army Corps of Engineers CRD C48-73 “Permeability
of Concrete”.
- Concrete samples (treated and untreated) to
have design strength of 2000 psi (13.8 MPa) and
thickness of 2 inches (50 mm). No admixtures permitted.
- Samples to be pressure tested to 175 psi (405
foot head of water) or 1.2 MPa (123.4 m head
of water).
- Treated samples, after crystalline growth has
occurred, shall exhibit no measurable leakage.
E. Chemical Resistance:
Independent testing shall be performed according to
ASTM C267-82 (1990) and ASTM C39-86 “Chemical
Resistance of Mortars”.
- Concrete samples (treated and untreated) to
have design strength of 4000 psi (27.6 MPa). No
admixtures permitted.
- Untreated and treated specimens to be immersed
for a minimum of 84 days in following chemical
solutions: hydrochloric acid (3.5 pH), brake fluid,
transformer oil, ethylene glycol, toluene, caustic
soda.
- Treated specimens shall exhibit no detrimental
effects after exposure, and shall have a minimum
of 14% increase in compressive strength versus
untreated control specimens.

1.06 QUALITY ASSURANCE
A. Manufacturer Qualifications:
Manufacturer should be ISO 9001 registered, and shall
have no less than 10 years experience in manufacturing
the cementitious crystalline waterproofing materials
(dry shake) for the required work. Manufacturers that
cannot provide the performance test data specified
herein will not be considered for the project.

with waterproofing applicator, concrete placer, concrete
finisher, Architect/Engineer, owner’s representative,
and waterproofing manufacturer’s representative
to verify and review the following:
- Project requirements for waterproofing as set
out in Contract Document.
- Manufacturer’s product data including
application instructions.
- Procedures for substrate preparation, waterproofing
installation and concrete finishing.
D. Technical Consultation:
The waterproofing manufacturer’s representative

1.08 WARRANTY
A. Manufacturer’s Warranty: Manufacturer shall provide standard product warranty
executed by authorized company official. Term of warranty
shall be [specify term] years from Date of Substantial
Completion.
B. Applicator’s Warranty:
Applicator shall warrant the waterproofing installation
against defects caused by faulty workmanship or materials
for a period of [specify term] years from Date of
Substantial Completion. The warranty will cover the
surfaces treated and will bind the applicator to repair,
at his expense, any and all leaks through the treated
surfaces which are not due to structural weaknesses
or other causes beyond applicator’s control
such as fire, earthquake, tornado and hurricane.
The warranty shall read as follows:
1. Warranty: The applicator warrants that, upon completion
of the work, surfaces treated with cementitious crystalline
waterproofing will be and will remain free from water
leakage resulting from defective workmanship or materials
for a period of [specify term] years from Date of
Substantial Completion. In the event that water leakage
occurs within the warranty period from such causes,
the applicator shall, at its sole expense, repair,
replace or otherwise correct such defective workmanship
or materials. Applicator shall not be liable for consequential
damages and applicator’s liability shall be
limited to repair, replacement or correcting of defective
workmanship or materials. Applicator shall have no
responsibility with respect to water leakage or other
defects caused by structural failure or movement of
the structure, or any other causes beyond Applicator’s
control.
