1.03 SYSTEM DESCRIPTION
A. Cementitious Crystalline Waterproofing:
Blend of portland cement, fine treated silica sand and active proprietary chemicals. When mixed with water and applied as a cementitious coating, 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.
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:

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.
- Coatings to have maximum thickness of 0.05 inches
(1 mm) per coat with up to two coats 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 C 267-77 “Chemical Resistance of Mortars”
and ASTMC 39-86 “Compressive Strength of Cylindrical
Concrete Specimens”.
- Concrete samples (treated and untreated) to
have design strength of 4000 psi (27.6 MPa). No
admixtures permitted.
- Coatings to have maximum thickness of 0.05 inches
(1 mm) per coat with up to two coats permitted.
- Untreated and treated specimens to be immersed
for a minimum of 84 days in following chemical
solutions: hydrochloric acid (3.5pH), 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.
F. Potable Water Approval:
Independent testing shall be performed according to
NSF Standard 61 and approval for use of waterproofing
material on structures holding potable water shall
be evidenced by NSF certification.

1.09 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 his 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
