Quality Control Documents
1. BBA Certificate 05/4217.
2. Factory Production Control Certificate 14/F086.
Permeability:
1. When tested to BS EN 12390-8 or DIN 1048-5 at <0.5 MPa><<72.5 psi>> for 72 hours, the permeability of treated concrete will be reduced by 70% over untreated concrete.
2. When using the Taywood / Valenta method of testing to modified BS EN 12390-8 at <1 MPa><<150 psi>> for 96 hours and then measuring and calculating the coefficient of permeability, the permeability of treated concrete will be reduced by a minimum of 70% over untreated concrete.
3. When tested to USACE CRD C48, no passage of water through treated samples when exposed to a vertical water head equal to 200 psi (460 foot head pressure) for 14 days.
4. When tested to USACE CRD C48, treated samples exposed to a vertical water head equal to 200 psi (460 foot head pressure) for 14 days will show a reduced coefficient of permeability of 97%.
B. Compressive Strength: Treated concrete must have compressive strength equal or higher than plain concrete when tested to ASTM C39/C39M at 28 days.
C. Drying Shrinkage: Minimum 20% reduced drying shrinkage for treated concrete when tested to ASTM C157.
D. Self-Sealing: Autogenous crack sealing of treated concrete for cracks with width of <0.5mm><<0.02 inches>> or greater; verified by independent testing.
E. Chemical Resistance: The waterproofing admixture shall improve sulphuric acid resistance of cement-based materials by blocking capillary pores to reduce acid penetration.
F. Corrosion of Reinforcing Steel:
1. Field Performance - The waterproofing admixture must provide enhanced corrosion resistance to embedded steel such that low half-cell readings and no noticeable signs of corrosion are evident after 10 years exposure directly in the corrosive marine tidal zone whereas untreated panels show evidence of corrosion.
2. Testing following ASTM G109 and ASTM C876, and assessed using half-cell measurements, macro cell corrosion rate, and lineral polarization resistance (LPR) after exposure to severe corrosive conditions, must demonstrate that the waterproofing admixture significantly delays the onset of corrosive conditions and reduces corrosion rates.
G. Evidence of Crystallization:
1. Manufacturer must present independent evidence of waterproofing crystals using both optical imaging and scanning electronic microscope (SEM) to verify waterproofing crystals are needle-shaped.
2. The manufacturer must present independent evidence using Energy Dispersive X-Ray Spectroscopy (EDS) that waterproofing crystals are distinct from ettringite crystals.
H. Bonding of coatings and finishes – Manufacturer must present tensile pull-off testing showing that the waterproofing admixture does not reduce the bond strength of subsequent coatings or finishes, with examples of using four different coatings (acrylic coating, rubber coating, epoxy coating, and tile thin-set).
