 |
Use a rotary hammer drill or pneumatic air drilling machine with a drill bit complying with ANSI B212.15.1994 tolerance standards. |
|
Drill depth is a minimum four times rod diameter thru maximum nine times rod diameter. See attached tables for general guidelines and construction specifications for specific requirements. |
|
Use a drill bit equal to the rod diameter plus 1/16” (for 3/8”ø and 1/2”ø) and 1/8” (for 5/8”ø and above). |
|
The 3/8”ø and 1/2”ø are acceptable for overhead, horizontal, and floor installation direction. The 5/8”ø and above permitted for horizontal and floor installation direction only. |
|
Per construction specification, adhere to minimum spacing, minimum edge distance, and minimum member thickness.
|
 |
|
Oscillate a clean air nozzle in and out of the hole four times, for a total of four seconds, starting at the bottom, with contaminant free compressed air exhausting hole until visually clean (i.e., no trace oils, antifreeze, et cetera). |
|
If hole is water filled or contains sludge/debris; the hole can be clean with pressured clean water for optimum cleaning method verse compressed air.
|
 |
|
Select and insert an appropriately sized Red Head brush from part no. SB038, SB012, SB058, SB034, SB078, SB010, SB125, or match color to anchor diameter. See attached brush specifications table. |
|
Insert brush into the hole with a clockwise motion, while completing one full turn for every 1/2” forward advancement further until bottom is reached. For faster and more suitable cleaning, attach the brush to a drill.
|
 |
|
Twist/Spin the brush four full turns at bottom of the hole.
|
 |
|
Using a clockwise motion, for every full turn of the brush, pull the brush 1/2” out of the hole. |
|
Air clean the dust or water clean the slurry off of brush to prevent clogging of brush.
|
 |
|
Oscillate a clean air nozzle in and out of the hole four times, for a total of four seconds, starting at the bottom with contaminant free compressed air exhausting hole until visually clean. |
|
Or, use pressure clean water to clean.
|
 |
|
Assemble Red Head supplied cartridge and nozzle. |
|
Place assembly into a hand or pneumatic injection tool. Dispense mixed adhesive outside of hole until uniform color is achieved. |
|
Insert the nozzle tip to the far end of the hole, inject the adhesive at an angle from the bottom into the hole and leave the nozzle tip always slightly below the fill level working, in a slow circular direction, work the adhesive into the side of the hole, filling slowly to prevent air entrapment, until the hole is filled 60% full. After installing the anchor the gap between the rod and the concrete must be completely filled with adhesive. |
|
If the working time has not expired the rod can be removed from the under filled holes and additional adhesives can be injected into the hole. Otherwise the installation shall be rejected. For flush application trowel off excess. |
|
For holes that contain water, keep injecting below the water and the adhesive will displace the water upward and prevent drawing water into the adhesive. |
|
During installation, concrete must be between 50°F to 110°F or artificially maintained.
|
 |
|
Insert rod with a counterclockwise motion to prevent air entrapment. |
|
Install rod into adhesive without delay after adhesive is injected into hole during working time of the adhesive. |
|
Insure that the adhesive fills voids, crevices and uniformly coats rod and concrete. |
|
Carefully work out the air pockets with an oil, rust and scale free rod, pushing to bottom of the hole while twisting and jiggling to ensure coverage.
|
 |
|
Jiggle rod slightly, immediately after installation, and do not disturb during working time. |
|
Cure time is 24 hours. |
