FX-70 Epoxy Method Installation Guide Timber Pile Steel Pile Concrete Pile 1300 STRONGTIE www.strongtie.com.au
Timber Pile-Epoxy Method I: Surface Preparation 1. Surface must be at least 4 C prior to application. 2. Consult a qualified engineer in cases when section loss exceeds 25 percent. 3. All wood surfaces to be covered with pile jackets shall be thoroughly cleaned of oil, grease, dirt, and any other deleterious material which would prevent proper bonding. 4. FX-70 jacket placement should not proceed until pile cleaning has been approved by the Engineer of Record or Owner s Representative. II: Jacket preparation: 1. All submerged jackets should be installed by certified professional divers. All jackets must be sealed appropriately to prevent grout leakage during installation. 2. FX-Spacers, standoffs and pumping ports are shipped unattached to be field installed. 3. FX-Spacers to be adhered to the inside of the jacket using an Simpson Strong-Tie recommended flexible adhesive suitable for bonding fibreglass to fibreglass. Please contact Simpson Strong-Tie for further details. 4. Installation and positioning of FX-Spacers and/or Pumping Ports is unique to each application. III: Jacket positioning: 1. Prepare a cartridge of FX-763 Low-Modulus Trowel-Grade Epoxy per manufacturer s published instructions and place a bead of epoxy into the female portion of the tongue-and-groove joint. 2. Spread jacket open and place around pile. 3. Allow jacket to return to original shape engaging interlocking joint and secure with ratchet straps if necessary. 4. Set jacket at proper elevation positioning jacket so there is minimum 46 cm of undamaged pile inside the jacket above and below the damaged area. 5. To secure the interlocking joint, install self-drilling, self-tapping type-316 stainless steel screws into the tongue-and-groove joint every 15 cm on centre. 6. Install external bracing. 7. Install FX-Backer Rod to create a temporary bottom seal; bottom seal may be installed prior to placing jacket. 8. If using a compactible fill material, a temporary bottom seal may not be necessary, contact Simpson Strong-Tie for more information 2 Simpson Strong Tie FX70-AU17-EPOXYMETHODS-IG 2017 Simpson Strong Tie Company Inc.
Timber Pile-Epoxy Method IV: FX-70-6MP Multi-Purpose Marine Epoxy Grout: 1. Prepare FX-70-6MP per manufacturer s published instructions: a. For optimal product performance, condition individual components to 21 C and stir liquid components thoroughly prior to use. Proportion Component A and Component B at a 2A:1B ratio by volume in a clean pail. Mix thoroughly with a low-speed (300 600 rpm) drill and mixing paddle for 2 3 minutes, scraping unmixed material from sides and bottom of mixing container as needed, taking care to prevent air entrapment. Continue mixing, and slowly add Component C to avoid clumping at a rate of 45 70 kg per 11.4 L unit of epoxy, scraping the sides and bottom as needed. Mix for approximately 2 3 minutes or until a uniform consistency is achieved. *For mixing in a 20 L pail, combine 3.8 L of Component A and 1.9 L of Component B in a clean mixing vessel with a slow-speed (300-600 rpm) drill and mixing paddle for a minimum of 2 minutes. While continuing to mix, slowly add (1) 22.7 kg bag of FX-70-6 MP C Component, scraping sides and bottom of pail as needed to ensure thorough mixing. Mix until FX-70-6 MP C Component is fully wetted and a uniform consistency is achieved. V: Bottom Seal Application: 1. Mix FX-70-6MP per manufacturer s published instructions (refer to section IV). 2. Place FX-70-6MP into the bottom 15 cm of the annular void by pouring or pumping. 3. If pouring, a specially fabricated funnel or flexible traffic cone may be helpful. 4. Allow seal to cure in accordance with published cure schedule before proceeding with repair. VI: Filler Grout Application 1. Mix FX-70-6MP per manufacturer s published instructions. Grout may be poured, pumped, or placed by tremie method. 2. To pour: a. FX-70-6MP can be poured from the top of jacket through standing water. 3. For tremie applications: a. Ensure the hose extends to the bottom of the jacket. Fill the jacket until the grout reaches the top of the jacket, allowing water to displace from the top of the jacket. Depending on the depth of the pour and size of the jacket, the tremie hose may need to be retracted as the jacket fills to maintain flow. 4. To pump: a. Contact Simpson Strong-Tie for injection port installation instructions suitable for your application. b. Begin by pumping FX-70-6MP into the lowest port. Grout shall be continuously injected until the grout reaches the top of the jacket. c. At the Contractor s option, multiple levels of grout ports may be installed to minimize the pumping pressure. For this method, injection shall begin at the lowest port and continue until the grout appears at the port above the injected port. When this occurs, close the injected port and continue injection at the port where grout appears. The injection process shall be continuous, except for brief interruptions when the injector is moved from port to port, until the grout reaches the top of the jacket.

Timber Pile-Epoxy Method VII: Epoxy Bevel Construction: Prior to bevel installation, allow FX-70-6MP Multi-Purpose Marine Epoxy Grout to set for a minimum of 6 hours at 21 C. 1. Prepare FX-763 Trowel-Grade Epoxy Mortar per manufacturer s published instructions: a. For optimal product performance, condition individual components to 21 C. Proportion Component A and Component B at a 2A:1B ratio by volume in a clean pail. Mix thoroughly with a low-speed (300 600 rpm) drill and mixing paddle for 2 3 minutes, scraping unmixed material from sides and bottom of mixing container as needed, taking care to prevent air entrapment. Continue mixing, and slowly add one part FX-701 filler by volume per part of mixed epoxy, scraping the sides and bottom as needed. Mix for approximately 2 3 minutes or until FX-701 is thoroughly wetted. 2. Immediately construct bevel with FX-763, taking care to construct slope which will not allow water to pond. VIII: Completion of work: 1. Remove external bracing after all materials have fully cured in accordance with published cure schedules. 2. Clean exterior surfaces of jackets of any filler material or other extraneous material deposited on the pile jackets. IX: Suggested tool list: 1. Equipment to properly prepare the pile surface chosen by contractor and Engineer of Record 2. PPE gloves, safety glasses, respirators etc. 3. Generator 4. EDT22S manual dispensing tool 5. Ratchet straps 6. Small drill and hex tex adapter to set self-tapping stainless steel screws in interlocking joint. 7. Slow-speed mixing drill and mixing paddle 8. Clean measuring vessels 9. Clean 20 litre buckets for mixing 10. Mortar Mixer (stationary drum with moving blades) 11. Pump equipment (Please contact Simpson Strong-Tie for further information) 12. Various hand tools shovel, hammer, trowels etc. 4 Simpson Strong Tie FX70-AU17-EPOXYMETHODS-IG 2017 Simpson Strong Tie Company Inc.
