Installation Instructions: Solid Base Materials

Drilling

1. Drill a hole into the base material with a rotary hammer drill (i.e., percussion drill) and a carbide drill bit to the size and embedment required by the selected steel hardware element (reference installation specifications for threaded rod and reinforcing bar). The tolerances of the carbide drill bits, including hollow bits, must meet ANSI Standard B212.15. Follow all tool instructions.
   Precaution: Use suitable eye and skin protection. Avoid inhalation of dust during drilling and/or removal (see optional dust extraction equipment supplied by DEWALT to minimize dust emission).
   Note! In case of standing water in the drilled hole (flooded hole condition), all the water has to be removed from the hole (e.g., vacuum, compressed air, etc.) prior to cleaning.
   Drilling in dry base material is necessary when using hollow drill bits (vacuum must be on); not for use in wet concrete or masonry. GO TO STEP 3 FOR HOLES DRILLED WITH DUSTX+™ DRILLING AND CLEANING SYSTEM; OTHERWISE GO TO STEP 2A.

Hole Cleaning

1. Starting from the bottom or back of the anchor hole, blow the hole clean using a compressed air nozzle (min. 90 psi) or a hand pump (min. volume 25 fl. oz.) supplied by DEWALT) a minimum of four times (4x).
   Use a compressed air nozzle or a hand pump for anchor rod diameters 3/8" to 3/4" or reinforcing bar (rebar) sizes #3 to #6.
   Use a compressed air nozzle for anchor rod diameter 7/8" to 1-1/4" and rebar sizes #7 to #10. Do not use a hand pump for these sizes.
2. Determine wire brush diameter (see installation specifications) and attach the brush with adaptor to a rotary drill tool or battery screwgun. Brush the hole with the selected wire brush a minimum of four times (4x). A brush extension (supplied by DEWALT) should be used for holes drilled deeper than the listed brush length.
   Note! The wire brush diameter should be checked periodically during use. The brush should resist insertion into the drilled hole and come into contact with the sides of the drilled hole. If not, the brush is too small and must be replaced.
3. Finally, blow the hole clean again using a compressed air nozzle (min. 90 psi) or a hand pump (min. volume 25 fl.oz.) supplied by DEWALT a minimum of four times (4x).
   Use a compressed air nozzle or a hand pump for anchor rod diameters 3/8" to 3/4" or reinforcing bar (rebar) sizes #3 to #6.
   Use a compressed air nozzle for anchor rod diameters 7/8" to 1-1/4" and rebar sizes #7 to #10. Do not use a hand pump for these sizes.
   When finished, the hole should be clean and free of dust, debris, ice, grease, oil, or other foreign material.

Preparing

1. Check adhesive expiration date on cartridge label. Do not use expired product. Review Safety Data Sheet (SDS) before use. Cartridge temperature must be between 23°F to 95°F (-5°C to 35°C) when in use for concrete unless otherwise noted. Cartridge temperature must be between 41°F to 95°F (5°C to 35°C) when in use for masonry. Review gel (working) and cure time table. Consideration should be given to the reduced gel (working) time of the adhesive in warm temperatures.
   Remove cap from cartridge.
   Attach a supplied mixing nozzle to the cartridge. Unless otherwise noted, do not modify the mixer in any way. Make sure the mixing element is inside the nozzle. Load the cartridge into the correct dispensing tool.
   Note! Use a new mixing nozzle with new cartridges of adhesive and also for all work interruptions exceeding the published gel (working) time of the adhesive.
2. Prior to inserting the anchor rod or rebar into the drilled hole, the position of the embedment depth has to be marked on the anchor.
   Verify anchor element is straight and free of surface damage.
3. Adhesive must be properly mixed to achieve published properties. For new cartridges and nozzles, prior to dispensing adhesive into the drilled hole, separately dispense at least three full strokes of adhesive through the mixing nozzle until the adhesive is a consistent GRAY color.
   Unless otherwise noted, do not attach a used nozzle when changing to a new cartridge.
   Review and note the published working and cure times (see gel time and curing time table) prior to injection of the mixed adhesive into the cleaned anchor hole.

Installation

1. Fill the cleaned hole approximately two-thirds full with mixed adhesive starting from the bottom or back of the anchor hole. Slowly withdraw the mixing nozzle as the hole fills to avoid creating air pockets or voids. If the bottom or back of the anchor hole is not reached with the mixing nozzle only, a plastic extension tube supplied by DEWALT must be used with the mixing nozzle (see reference tables for installation).
   Piston plugs must be used with and attached to mixing nozzle and extension tube for overhead (i.e., upwardly inclined) installations and horizontal installations with anchor sizes as indicated in the piston plug selection table. Insert piston plug to the back of the drilled hole and inject as described in the method above. During installation, the piston plug will be naturally extruded from the drilled hole by the adhesive pressure.
   Attention! Do not install anchors overhead without proper training and installation hardware provided by DEWALT. Contact DEWALT for details.
2. The anchor should be free of dirt, grease, oil, or other foreign material. Push clean threaded rod or reinforcing bar into the anchor hole while turning slightly to ensure positive distribution of the adhesive until the embedment depth is reached. Observe the gel (working) time.
3. Be sure the rod or rebar is fully seated at the bottom of the hole to the specified embedment. Adhesive must completely fill the annular gap between the anchor and the base material. Protect exposed anchor threads from fouling with adhesive. For all installations, the anchor must be restrained from movement throughout the specified curing period (as necessary) where necessary through the use of temporary wedges, external supports, or other methods. Minor adjustments to the position of the anchor element may be performed during the gel (working) time only.

Curing and Loading

1. Allow the adhesive anchor to cure to the specified full curing time prior to applying any load (reference gel time and curing time table).
   Do not disturb, torque, or load the anchor until it is fully cured.
2. After full curing of the adhesive anchor, a fixture can be installed to the anchor and tightened up to the maximum torque (reference gel time and curing table) by using a calibrated torque wrench.
   Note! Take care not to exceed the maximum torque for the selected anchor.

Reference Installation Tables

Gel (working) Time and Curing Table

*Minimum temperature of base material is 14°F (-10°C) for concrete and 23°F (-5°C) for concrete masonry base materials. Cartridge temperature must be between 23°F to 95°F (-5°C to 35°C) when in use for concrete except for installations in base material temperatures between 14°F and 23°F (-10°C and -5°C) the cartridge temperature must be conditioned to between 68°F and 95°F (20°C - 35°C). Cartridge temperature must be between 41°F to 95°F (5°C to 35°C) when in use for masonry. Linear interpolation to determine approximate gel and full curing times for intermediate base material temperatures is allowed.

2. All horizontal installations require the use of piston plugs where the embedment depth is greater than 8 inches and the drill bit size is larger than 5/8-inch.
3. The use of piston plugs is also recommended for underwater installations where one is tabulated together with the anchor size.
4. A flexible plastic extension tube (Cat. #08281-PWR or #08297-PWR) or equivalent approved by DEWALT must be used with piston plugs.
