Installation Guidelines

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.
