- Applications
Hypel-D is an integral waterrepellant admixture system for use in:
• Paving stones
• Architectural concrete block
• Concrete brick
• Grout
• Concrete roofing tile- Dosage Rate
Hypel-D is recommended for use at the following dosages:
- 12-25 ozs./cwt.- Normal Weight Concrete Block (783-1630 ml/100kg)
- 16-30 ozs./cwt.-Medium Weight Concrete Block (1043-1956 ml/100kg)
- 24-40 ozs./cwt.-Lightweight Concrete Block (1565-2608 ml/100kg)
- 4-20 ozs./cwt.-Concrete Paving Stones (260 - 1305 ml/100kg)
Because local job conditions vary and optimum dosages need to be determined, contact your local RussTech technical service representative for further assistance to ensure proper water repellant system performance.

Technical Details & Test Data
- Technical Note
Flashing and weep hole design details are available upon request. Efflorescence occurs when excess calcium salts become soluble again from moisture in the environment around the concrete or masonry unit. External sources of moisture can be humidity, rainfall, condensation, or snow etc. When these salts become soluble, they migrate to the surface during the evaporation process, consequently, staining the surface.
Hypel-D effectively reduces moisture from penetrating the surface and may be helpful in stopping salts from becoming soluble and migrating to the surface. It is important to point out though, that the addition of Hypel-D alone, will not guarantee the control of efflorescence.
Safety & Health
- Precautions
Hypel-D will not correct building design flaws, out of specification materials, mix proportion errors, incorrect manufacturing procedures, or improper construction practices. Proper block manufacturing procedures, mixing, and proportioning of mixes must be incorporated.
RUSSTECH cannot be responsible for the incorrect use of Hypel-D.
If necessary, only use mild acid for cleanup. Do not use high pressure cleaning methods.
Packaging & Availability
- Packaging
55-gallon drums, 275-gallon totes, and bulk delivery.
Storage & Handling
- Shelf Life
- 6 Months
- Storage
Hypel-D may freeze at temperatures below 40F (4 C). Freezing will harm this material, so, precautions should be taken to protect it from freezing. If it should freeze, it will no longer be effective in the masonry units and should be discarded. Also, Hypel-D should be stored in sealed containers where temperatures don’t exceed 118 F (48 C).
