- Process
- Moisture and free lime within the mix combine with the active chemicals in the DuraTite® Crystalline Admix to create a continuous barrier of insoluble crystals which penetrate deep into the capillary structure of the concrete.
- These capillaries and interstices are blocked to the passage of water, whilst permitting the transmission of air and water vapor, enabling the structure to breathe.
- The rate of crystalline development varies with the variations in the mix design and curing regime of the concrete.
- However the crystalline development is usually sufficient to provide full waterproofing properties approximately 7 - 10 days after placement.
- DuraTite® Crystalline Admix is equally effective against both negative and positive water or osmotic pressure.
- After the initial crystallization process has successfully waterproofed the structure, the active chemicals within DuraTite® Crystalline Admix remain dormant in the concrete to off er long-term protection.
- Any later contact with water will reactivate the sealing process.
- Product Application
Application
- DuraTite® Crystalline Admix may be added to the concrete either at the batching plant or added to the mixer at the job site.
- It is preferable that DuraTite® Crystalline Admix is added to the dry mix to ensure even distribution prior to the addition of water.
- If DuraTite® Crystalline Admix is added after the addition of water, mixing must continue for an additional 10 minutes prior to placement of the mix.
- Do not apply if the ambient temperatures are below 4°C or above 35°C.
Application Rates
22 ounces per cubic yard (0.8 kg per cubic meter) of concrete.
Application Method
- Apply the DuraTite Concrete Crystalline Admix to the concrete mixture at about 22 ounces per cubic yard (0.8kg/m3 ).
- If using prepackaged product, 1 - bag per cubic yard.
- Curing
- Concrete containing DuraTite® Crystalline Admix must be prevented from drying out too rapidly and should be kept damp for at least 7 days.
- Mist spraying with water and covering with polyethylene is effective to prevent drying.
- Curing compounds are not recommended for use with DuraTite® Crystalline Admix.
- Protect from weathering, sun, frost, and wind for at least 7 days.
