- Advantages
- High strength, high modulus and low-viscosity structural adhesive.
- Moisture tolerant-it curves underwater.
- Fully compatible and excellent adhesion to PileMedic® carbon or glass laminates.
- Convenient easy mix ratio, 2:1 by volume.
- 100% solids, VOC free and Butyl Glycidyl Ether (BGE) free.
- Nearly odor-free.
Applications & Uses
- Markets
- Applications
- Uses
- Filing the annular space created between the PileMedic® and concrete or timber pile or pole being repaired for both above water and submerged conditions.
- As a binder mixed with sand and small-size aggregates to form a resin-based grout to fill larger annular spaces in the repair of piles and poles using PileMedic®.
- Filling cracks in concrete by injection or gravity feed.
- Crack repairs in masonry, wood and concrete structural members.
- Coverage
- Apply as a filler material to fill voids in concrete, masonry, and timber structures.
- The application rate varies greatly based on the porosity and the volume of voids or annular spaces present.
- For wider annular spaces, the epoxy can easily be mixed with clean silica sand and pea gravel (3/8 inch and under) for improved yield.
- Application Equipment
Metering or dispensing equipment with ratio capabilities of 2:1 and viscosity range of 100 - 5000 cps.
- Surface Preparation
Surfaces must be entirely free of oil, grease, dirt, detergent, surface water, laitance, curing compounds, coatings or other contaminants that may interfere with adhesion.
- Mixing
- Mix 2 parts resin “A” to 1 part hardener “B” by volume into a clean container.
- Alternatively, proportion parts “A” and “B” to a weight ratio of 100:45.
- Mix thoroughly for 3 minutes using a paddle at low speed (400 - 600 rpm) to avoid air entrainment.
- Mix only the quantities that can be used within the pot life.
- Remember you will have less working time at higher temperatures.
- Do not thin; solvents will prevent proper cure.
- If desired, silica sand and well-grained pea gravel (3/8 inch and under) can be added up to a maximum of 50 pounds of sand and gravel per gallon of QuakeBond™ 320LV.
5-gallon Kit:
- Pre portion batches.
- Pour Part B hardener into Part A resin.
- Hand mix for 3 minutes, scraping sides and bottom of the container to ensure complete mixing.
55-gallon Kit:
- Pre portion batches.
- Pour Part B hardener into Part A resin.
- Mix for 3 minutes using a Jiffy mixer head and a mechanical drill.
- To ensure complete mixing, scrape the sides and bottom of the container and continue mixing for an additional 1 to 2 minutes.
- Do not hand mix.
- Application
- Properly mixed QuakeBond™ 320LV can be used to fill the annular space between PileMedic® jackets and the pile or pole being repaired.
- When introduced at the bottom of the annular space, the high density of the resin pushes the entrapped water to the top.
- The resin can be thickened with clean silica sand and pea gravel (3/8 inch and under) for filling larger annular spaces.
- All epoxy components shall be preconditioned to be at a temperature between 65°F (17°C) and 85°F (29°C) prior to the time of mixing.
- Limitations
- The minimum application temperature of the epoxy is 45°F (7°C).
- Do not thin the epoxy with solvents.
- This is not a crack injection resin.
- Never install to a thickness greater than ½” without the presence of aggregate.
- In large mass, the product will exotherm, possible bubbling might occur, consult QuakeWrap expert.
- Cleanup
- Uncured materials can be removed with an approved solvent or warm soapy water.
- Cured materials can only be removed mechanically.

Safety & Health
- Safety Precautions
- Avoid inhalation of vapors.
- Forced local exhaust is recommended to effectively minimize exposure.
- NIOSH approved, organic vapor respirators and forced exhaust is recommended in confined areas, or when conditions may cause high vapor concentrations.
- Do not weld on, burn, or touch any epoxy materials as this will cause a release of hazardous vapors.
- Consult MSDS for detailed information.
