The PileMedic® system consists of a complete line of products for repair and strengthening of columns and piles that have been developed over a decade. These components include:

1. PileMedic® laminates (4-ft long by various lengths)
2. Spacers of various shapes and sizes to properly define the annular space and placement of longitudinal reinforcing bars (when required)
3. Special epoxies that cure under water — eliminating the need for coffer dams
4. Different solutions for sealing the bottom of the annular space
5. Patented ShearWrap™ and ShearClamp™ for load transfer in repair of steel piles
6. Underwater grouts and grout additives

Once the pile surface has been cleaned, the installation consists of the following steps:

1. Pass the required number of spacers through zip-tie and wrap and secure the zip-tie and spacers on the pile; this step must be repeated every 2-3 feet along the repair height; watch video
2. If required, snap the GFRP or steel reinforcing bars into the spacers
3. Cut the required length of 4-ft wide PileMedic® laminate (watch video); standard detail requires wrapping the laminate twice around the pile (720 degrees) plus an 8-inch overlap. Make sure you use the circumference of the jacket including the annular space and not just the pile.
4. Measure and mix the provided 2-part epoxy paste with the appropriate mix ratio until you achieve a uniform color mix. Alternatively, 900-ml packages are available that can be dispensed with a pneumatic gun and a static mixer.
5. Apply the epoxy paste to the overlapping portion of the laminate (one circumference + 8 inches) with a thickness of 0.030 inches using a trowel
6. Wrap the laminate around the spacers with the uncoated portion of the laminate in contact with the spacers; the second half of the laminate which is coated with epoxy will be wrapped around the first half.
7. Tighten the laminate onto itself; at this stage the epoxy paste acts like a lubricant and allows for easy adjustments.
8. Secure the laminate with a couple of ratchet straps to prevent it from unraveling while the epoxy paste cures.
9. Repeat steps 4 through 8, overlapping each new jacket by 4 inches over the previously installed jacket; the overlap region must be coated with a layer of the same epoxy paste. Continue until a jacket of desired height (length) has been produced.
10. Push the bottom of the jacket into the sea bed or use one of our bottom seal options to create a seal above the sea floor.
11. Fill the annular space with the appropriate grout using the tremie method or pumps with the optional grout ports that we supply. It is recommended to fill the annular space for a height of 6-12 inches and allow that to set to form a seal before the jacket is filled to the top.
12. Remove the ratchet straps.
