- Product Application
- TechCrete® Concrete 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 TechCrete® Concrete Admix is added to the dry mix to ensure even distribution prior to the addition of water.
- If TechCrete® Concrete 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 (+39°F) or above +35°C (+95°F).
- Application Rates (Normal) - 22 ounces per cubic yard (0.8 kg per cubic meter) of concrete.
- Application Method - Apply the TTechCrete® Concrete Admix to the concrete mixture at about 22 ounces per cubic yard.
- If using pre-packaged product, use 1 bag per cubic yard.
- Curing
- Concrete containing TechCrete® Concrete 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 TechCrete® Concrete Admix.
- Protect from weathering, sun, frost and wind for at least 7 days.
Technical Details & Test Data
- Performance Characteristics
Moisture and free lime within the mix combine with the active chemicals in the TechCrete Concrete 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.
TechCrete Concrete 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 TechCrete Concrete Admix remain dormant in the concrete to offer long-term protection. Any later contact with water will reactivate the sealing process.
