Tests indicate that the use of Hex-3R FibrAnchors significantly increases shear strength.

Hex-3R FibrAnchors can be applied before or after the Hex-3R Wrap:
Application before Hex-3R Wrap
To ensure proper anchorage, apply even pressure in an outward motion on surface of Hex-3R Wrap where the anchors are installed. The “fan” of anchor threads must be completely laminated to the Hex-3R Wrap.
   
1.

Drill hole in the prepared concrete as per dimensions on drawings. Prepared concrete is defined as sand blasted clean, holes/depressions are filled and protrusions are ground down.
2.
Apply epoxy prime coats as per Hex-3R Wrap instructions. Note : the installation of the Hex-3R FibrAnchors and Hex-3R Wrap must be applied as a system (before the epoxy is fully cured) in order to form a laminate.
3.

Fold the Hex-3R FibrAnchor in half and insert into the resin-filled hole using a rod or probe. Ensure that the Hex-3R FibrAnchor reaches the bottom of the hole

– Or-

Fold the Hex-3R FibrAnchor in half on the tip of an epoxy tube applicator and insert into the hole. Eject the resin into the hole and at the same time the Hex-3R FibrAnchor will be pushed into place.
4.
Bend the protruding ends of the Hex-3R FibrAnchor over, spread the fibers over the surface and embed them in the resin film on the surface of the saturated fabric layer.
5.
Install saturated layer of Hex-3R Wrap as per plans over Hex-3R FibrAnchors. Smooth down the surface of the fabric to remove any entrapped air and apply even pressure in an outward motion where the anchors are installed. The “fan” of anchor threads must be completely laminated to the Hex-3R Wrap
6.
Apply successive layers of Hex-3R Wrap as per plans.
   
Application through Hex-3R Wrap
Hex-3R FibrAnchors installed through the laminate ensure proper contact between the anchor “fan” and the Hex-3R Wrap. This type of installation pins the Hex-3R Wrap against the concrete surface. Note that the Hex-3R FibrAnchors may be installed after the Hex-3R Wrap has cured.
The two drawbacks of this method are :– the Hex-3R Wrap system is locally damaged at the holes

– the surface of Hex-3R Wrap around the hole must be roughened to ensure a proper laminate bond between the anchor “fan” and the Hex-3R Wrap.

Use medium grit sandpaper to roughen the laminate surface, being careful not to damage the fabric fibers.
1.
Drill hole in the prepared concrete as per dimensions on drawings. Prepared concrete is defined as sand blasted clean, holes/depressions are filled and protrusions are ground down.
2.
Apply epoxy prime coats as per Hex-3R Wrap instructions. Note : the installation of the Hex-3R FibrAnchors and Hex-3R Wrap must be applied as a system (before the epoxy is fully cured) in order to form a laminate.
3.
Insert a short dowel (about 70 mm (3″), under 10 mm (3/8″) in diameter) to mark hole locations. Apply initial saturated Hex-3R Wrap layers, carefully parting the fibers around the dowel and pressing the fiber tows smooth to the wall surface. Remove dowel and fill hole with resin immediately prior to installing Hex-3R FibrAnchors.
4.

Fold the Hex-3R FibrAnchor the Hex-3R FibrAnchor in half and insert into the resin-filled hole using a rod or probe. Ensure that the Hex-3R FibrAnchor reaches the bottom of the hole

– Or-

Fold the Hex-3R FibrAnchor in half on the tip of an epoxy tube applicator and insert into the hole. Eject the resin into the hole and at the same time the Hex-3R FibrAnchor will be pushed into place.
5.
Bend the protruding ends of the Hex-3R FibrAnchor over, spread the fibers over the surface and embed them in the resin film on the surface of the saturated fabric layer.
6.
Place the final saturated layer of fabric (face layer) over the previous layer and Hex-3R FibrAnchors. Smooth down the surface of the fabric to remove any entrapped air and apply even pressure in an outward motion where the anchors are installed. The “fan” of anchor threads must be completely laminated to the Hex-3R Wrap.
