Dock Pile Cap
Dock Pile Cap is Heat Shrink Cap, used to cover the top of the
Wooden Dock Pile & to protect it from ingress of water / moisture,
thereby increasing Dock Pile life. The caps are manufactured from high quality
Cross-linked Polyolefin material.
The Best & Cost-effective Solution for long term maintenance of Dock
Pile :
- Wood shrinks when losing moisture from the cell walls & swells when gaining moisture
in the cell walls. This shrinking & swelling can result in warping, splitting,
cracking mainly from top surface; which can cause gaps & loosening of Tool Handles.
Dock Piles which eliminates such problems & avoids extra cost of Clamps, used to
tighten the gaps; thereby avoiding long term maintenance of Dock Piles.
- Use of Dock Pile typically adds some nominal percentage to the total cost of New
Dock Pile replacement. Precaution is always better than cure.
Features:
- Hot melt adhesive lining provides 100% environmental sealing against weathering,
moisture, contamination and adverse environmental conditions according to IP 68.
- Resistance to UV rays & Ozone.
- Versatile and cost effective, as 5 sizes & covers Dock Pile dia. from 140 mm to
460 mm.
- Service life more than 30 years.
- Easy installation on concrete, wood, steel or composite poles in minutes.
Benefits :
- Once the heat applied, adhesive filled inside the top surface (optional) melts &
penetrates into the Dock Pile cracks and cavities, thereby reinforces the top of
the Dock Pile.
- Provides excellent Impact resistance, i.e. when a Dock Pile end is covered and
hits on a sharp edge, it would not crack.
- Prevents birds from perching (woodpecker damage) or nesting on top of round
tubular & solid Dock Piles.
- Protects the top of the Dock Pile from damage caused by freeze and thaw
conditions.
- No maintenance after installation
- Can also be used on marine pylons to protect piling from internal.

INSTALLATION INSTRUCTIONS
Dock Pile supplied by us are in an expanded form. When heated above 1250c they
attempt to shrink back to their original dimensions, conforming to the objects they
cover. Use a propane (preferred) or butane gas torch. Adjust the torch to obtain a
soft blue flame with a yellow tip. Pencil-like blue flames should be avoided. Keep
the flame moving continuously to avoid scorching the material.
-
Dock Pile Preparation :
If necessary, cut the Dock Pile end so that it is straight and even. Clean
and de-grease the Dock Pile surface that will come into contact with
sealant. (Fig. 1)
-
Installation of Dock Pile:
Place it over the top of the Dock Pile.(Fig. 2)
-
Shrink it into place, starting at the closed end and working towards the Dock
Pile. Adhesive will be visible at ends. (Fig. 3)
-
Properly installed will be smooth and conform to Dock Pile. Allow the Cap to
cool before applying any mechanical strain.(Fig. 4)
