1 8.1 CHEMICAL INJECTION ANCHORING 8.1 GENERAL INFORMATION Product is a High Performance Pure Epoxy Anchoring adhesive for use in Cracked and Non-Cracked concrete. For structures subject to external exposure, permanently damp or aggressive conditions. Benefits, Advantages and Features European Technical Approval option1 for use in cracked and non cracked concrete ETA-10/0309: Highest level of European approval for chemical anchors 100 Year design life Approved for flooded holes Approved for floor, wall & overhead applications Data for Sustained Loading Greater productivity: Anchors in dry, damp, wet or flooded holes No weather delays Fast and easy dispensing Greater security: Highest performance in cracked concrete Versatile pure epoxy: Anchors all stud & bar diameters in all directions Oversized holes Anchors in carbide drilled and diamond cored holes For tropical and Cold weather conditions Greater safety: Low odour Non-flammable Fire Rated : Refer Fire rated anchoring section Installation PERFORMANCE RELATED MATERIAL INSTALLATION RELATED Drill recommended diameter and depth hole. 2. Important: Use Ramset Dustless Drilling System to ensure holes are clean. Alternatively, clean dust and debris from hole with stiff wire or nylon brush and blower in the following sequence: blow x 4, brush x 3, blow x 4, brush x 3, blow x Insert mixing nozzle to bottom of hole. Fill hole to 3/4 the hole depth slowly, ensuring no air pockets form. 4. Insert Ramset /rebar to bottom of hole while turning. 5. Allow to cure as per setting times. 6. Attach fixture.
