Denso SeaShield 2000HD extends the life of underwater piles by years.

Protecting underwater piles from UV, impact, and corrosion is critical. Failure to maintain these marine structures properly results in unsafe structures and costly repair. Pile protection systems, such as the SeaShield Series 2000HD from Denso North America, offer the necessary protection and are fast and easy to apply, even underwater.

Denso outlines step-by-step instructions on the engineering specifications for its SeaShield Series 2000HD, to guide users through proper application. The guide shows that underwater pile protection is just a few simple steps away:

  1. Prepare the surface 
  • Ensure any weld spatter, sharp points, or edges are removed.
  • Remove loose paint, rust, foreign matter, or marine growth by wire brush.
  • High-pressure water blasting or a mechanical wire brush can also be used to help prepare the surface.
  • If the pile surface has pitting greater than two millimetres in depth, use Denso S105 paste to create a smooth surface. Apply the paste using a gloved hand to slowly rub the paste into the pits.
  1. Apply marine piling tape
  • Hold the tape end firmly against the starting point and press it into the pile surface.
  • Begin unrolling the tape while holding the roll close to the pile, using a 55 per cent overlap. Avoid getting a long lead of tape, as that can lead to folding and gaps on the surface being wrapped.
  • Keep enough tension on the tape to ensure continuous adhesion without stretching.
  • Press out any folds or air pockets as you proceed with application.
  • When it is time to start a new roll of tape, ensure at least six inches of overlap.
  • Smooth out the overlaps by running your hand along the tape in the direction of the spiral.
  1. Apply outercover
  • Wrap the outercover around the pile and align the holes with the fastener bars.
  • Secure the outercover using the specified bolts, nuts, and washers.
