Bigfoot Base Cap

The Bigfoot Base Cap (Cap) was designed to use the Bigfoot Systems in wet areas to prevent the concrete from losing its strength when submersed in water. By using the Cap it allows the user to submerse the system, which will produce a pier and footing in the water.

Instructions
  • Select the appropriate size Cap for the Bigfoot.
  • Place a 3/8” to ½” bead of DAP – Water Tight Roof Sealant around the outer edge of the Cap at the lip
  • Place the Bigfoot on the sealant pressing it firmly into the sealant.
  • Screw the Bigfoot fast to the Cap with eight 1” screws evenly spaced around the outer edge of the Bigfoot.
  • Using 2” long strips of duct tape cover all the air holes on the Bigfoot.
  • Once the tube size has been selected cut the rings off the Bigfoot above the ring being used.
  • Place a ½” bead of sealant around the ring and slide the tube onto the Bigfoot into the sealant.
  • Secure the tube to Bigfoot with four to six 1” screws.
  • Visually inspect all areas where sealant has been used to ensure there are no gaps where water may enter.
  • Place the system in the water and add just enough concrete, approximately 13 shovels full, to sink the system.
  • Position the system in place and backfill.
  • Then continue filling with concrete to the top.

Using the system in areas where backfill is not required use Steps 1 through 12 excluding Step 11. Use 1” screws spaced 6” apart when fastening the cap on to the bottom of the Bigfoot. In marine applications use a Marine Mix Concrete.
