Dock Retention Systems


Pencil and Sleeve
The most common method of holding a dock in position in our area. consists of a pencil ( a long piece of pipe that is a smaller diameter than the sleeve) and a sleeve, ( a short piece of pipe that is a larger diameter than the pencil and is attached to the dock). the pencil goes through the sleeve and into the earth and allows the sleeve to move up and down with fluctuating water levels. with this system, it is important that the land end of the walkway is able to move in and out as the geometry of the dock and bridge changes with fluctuating water levels. the pencils do not have to be driven into the ground, they will work themselves down with the constant back and forth movement of the dock and will stop when the resistance levels are great enough.

Shore Mount System
Developed for use on our smallest dock and bridge package (8’ x 12’ dock and 20’ walkway), our shore mount system offers quick and easy instalation w/ time tested reliability and also makes future dock location changes easily performed. the shore mount system consists of a pair of stake pockets on a hinge attached to the land end of the walkway that stakes are driven through and into the ground. stakes are typically between 16” and 36” depending on soil type

H-post and Cables
This system is used when water depth exceeds 20’ or the lake / pond bottom is rock or sandstone. this system consists of an h-post mounted in the earth that the land end of walkway is pinned to and cables that go from the dock to either secondary burried posts, criss cross back to the h-post or can go to trees or other fixed objects.

Stiff Arms
This system is used when water depth is excessive or the lake / pond bottom is rock or sandstone. this system consists of 2 or more structural members that are attached to the earth and to the dock. the walkway can be used as one of these members

Flexible Mooring Devices
This system is used when either other systems are unable to be used or when the sight of other retention devises are undesirable and unwanted. this system consists of typically 4 or more mooring devices ( a reinforced homogenous rubber hawser, much like a rubber band) and 4 or more dead weight anchors (typically concrete blocks) these mooring devices are engineered specifically for each customer and takes into account water depth at all 4 corners and min / max water level fluctuations

Encapsulated Floatation


Whats Inside?
Our corps of engineers approved floation consists of a ¼” thick virgin polyethylene protective outer shell and is filled w/ num.1 open cell styrofoam.

How Do They Mount?
Our floatation has 4 or more ( depending on size) mounting holes or knotches around the perimeter of the top of the float.

Can Floats Sit on Dry Ground?
Floats can sit on dry ground but could possibly be punctured by sharp rocks, stumps, pipe and other debris that may be present under the dock as the water level lowers.

What If It Gets Punctured?
A punctured float will still provide floatation. it will however support less weight as the styrofoam inside saturates with water. depending on weight load replacement may be required. repair of floats w/ sealants is usually a temporary fix and can last from 1 month to 3 years depending on location of repair and quality of sealants used. repair with thermo welding is a more pemanent fix but may not be cost effective.

How Long Will They Last?
Floats can last 40 plus yrs if not abused or punctured and carry a 15 year warranty

What is Hot Dip Galvanizing?
Hot dip galvanizing is the process of applying a protective zinc coating to steel or iron to prevent rust and corosion.

How is Galvanizing Done?
The pre-fabricated steel sections or pieces are sumberged in a bath of molten zinc until it reaches 840*f (449*c). at this point, the zinc reacts with the steel to form zinc/iron intermetallic layers on all surfaces inside and out.

How Long Does Galvanizing Last?
Life of the galvanizing depends greatly on environment. excessive salt or fertilizers etc., will cause the zinc to corode quicker. in most typical environments galvanizing can last 70 years or more.
