- Sealing of construction joints, cold joints and working joints in concrete, where reinjection may be necessary.
- Three independent injection channels
- Pressure activated apertures
- Durable construction
- Wire mesh for additional protection
- Foam pad adapts to irregular surface
The grout recommendation for the 1st injection (and 2nd injection if needed) beginning with the center channel is:
*Superflex AR prepared according to the product data sheet. This material will allow for subsequent injection without blocking apertures.
The grout preference for the 3rd injection if needed is:
- Injecto PURe with 1% Flex Cat PURe.
|Width||1 1/8 inch|
|Channel diameter||1/4 inch|
Procedure for the installation
Place TRIOject in the middle of the construction joint. With thick structural sections, greater than 20 inches, place TRIOject about 10 inches away from the external water side.
If two runs of TRIOject are used, the hoses should be at least 2 inches apart. The length of each run of hose should not exceed 26 ft.
Ensure continuous contact with joint by fastening the TRIOject mesh with nails at 1 ft. intervals.
After the concrete has cured 28 days, the first channel can be injected with Superflex AR acrylate grout.
