1. Tabulated values are calculated for concrete breakout or bond failue. Steel strength must also be checked against these val-ues. The lowest value controls. 2. Values are calculated using the conversion from Strength Design to ASD method as outlined in ICC-ES AC308 using a conver-sion factor based on a weighted average 30% Dead Loads and 70% Live Loads. 3. Tabulated values are only valid for single anchors without consideration for close edges or anchor spacing distances in dry concrete for the given temperature range. 4. Calculated values are for illustrative purposes only. Anchor design must be conducted by an engineer with experience in the design of fasteners and independently verified.

Solid Substrate Installation Method

1. Drill the hole to the correct diameter and depth. This can be done with either a rotary percussion or rotary hammer drilling machine depending upon the substrate.

2. Thoroughly clean the hole in the following sequence using a brush with the required extensions and a source of clean compressed air. For holes of 400mm or less deep, a blow pump may be used: Blow Clean x2 > Brush Clean x2 > Blow Clean x2 > Brush Clean x2 > Blow Clean x2.

If the hole collects water, the current best practice is to remove standing water before cleaning the hole and injecting the resin. Ideally, the resin should be injected into a properly cleaned, dry hole3. Select the appropriate static mixer nozzle for the installation, open the cartridge/foil pack and screw

nozzle onto the mouth of the cartridge. Insert the cartridge into a good quality applicator.4. Extrude the first part of the cartridge to waste until an even colour has been achieved without

streaking in the resin.5. If necessary, cut the extension tube to the depth of the hole and push onto the end of the mixer

nozzle, and (for rebars 16mm dia. or more) fit the correct resin stopper to the other end. Attach extension tubing and resin stopper.

6. Insert the mixer nozzle (resin stopper / extension tube if applicable) to the bottom of the hole. Begin to extrude the resin and slowly withdraw the mixer nozzle from the hole ensuring that there are no air voids as the mixer nozzle is withdrawn. Fill the hole to approximately ½ to ¾ full and withdraw the nozzle completely.

7. Insert the clean threaded bar, free from oil or other release agents, to the bottom of the hole using a back and forth twisting motion ensuring all the threads are thoroughly coated. Adjust to the cor rect position within the stated working time.

8. Any excess resin will be expelled from the hole evenly around the steel element showing that the hole is full. This excess resin should be removed from around the mouth of the hole before it sets.

9. Leave the anchor to cure. Do not disturb the anchor until the appropriate loading time, has elapsed depending on the substrate conditions and ambient temperature.

10. Attach the fixture and tighten the nut to the recommended torque. Do not overtighten.

MYT-BRONZE: Not to be used for overhead applications.

Hollow Substrate Installation Method

1. Drill the hole to the correct diameter and depth. This should be done with a rotary percussion drilling machine to reduce spalling.

2. Thoroughly clean the hole in the following sequence using the hole-cleaning brush with the required extensions and a source of clean compressed air. For holes of 400mm or less deep, a blow pump may be used: Brush Clean x1. Blow Clean x1.

3. Select the appropriate static mixer nozzle for the installation, open the cartridge/foil pack and screw nozzle onto the mouth of the cartridge. Insert the cartridge into a good quality applicator.

4. Extrude the first part of the cartridge to waste until an even colour has been achieved without streaking in the resin.

5. Select the appropriate perforated sleeve and insert into the hole.6. Insert the mixer nozzle to the bottom of the perforated sleeve, withdraw 2-3mm then begin to extrude the resin

and slowly withdraw the mixer nozzle from the hole ensuring that there are no air voids as the mixer nozzle is withdrawn. Fill the perforated sleeve and withdraw the nozzle completely.

7. Insert the clean threaded bar, free from oil or other release agents, to the bottom of the hole using a back and forth twisting motion ensuring all the threads are thoroughly coated. Adjust to the correct position within the stated working time.

8. Any excess resin will be expelled from the hole evenly around the steel element showing that the hole is full. This excess resin should be removed from around the mouth of the hole before it sets.

9. Leave the anchor to cure. Do not disturb the anchor until the appropriate loading time, has elapsed depending on the substrate conditions and ambient temperature.

10. Attach the fixture and tighten the nut to the recommended torque. Do not overtighten.

Important Notes

Use in Porous SubstratesThis bonded anchor is not intended for use as a cosmetic or decorative product. When anchoring into porous or reconstituted stone it is recommended that technical assistance is sought. Due to the nature of the product, migration of the monomer in the resin may cause staining in certain materials. If you are still uncertain, it is advisable to test the resin by applying it in a small, discrete area and testing before using the resin on the project.
