Our classic wood piling has the maximum treatment for saltwater immersion: 2.5 CCA. We carry lengths up to 60 ft. and in diameters from 5 to 16 in. We guarantee our supply is the best in the industry: straight, consistent, and high-quality. more
Piling keeps your dock supported and out of the water. Good piling is the basis of any long-lasting dock.

High pressure water jetting can increase pored water pressure around pile toe and create temporarily status that soil particles are moved easily. At the same time, upstreaming water flow reduces skin friction of pile and reduces interlock resistance by washing out soil inside interlock. Therefore Press-in with Water Jetting reduces penetration resistance, and enables the pile installation to be conducted with adequate press-in force. more
The water jet lubricates the pile surface and temporarily and locally loosens and softens the ground. As the water pressure and water flow can be controlled depending on the ground conditions, ground disturbance can be minimized by this regulated water flow.
The physics of water-witching is unclear, and it is not always successful. A geologist uses more scientifically-based methods to help you locate where to dig.
Begin by digging a pilot hole at least two feet deep using a hand auger or a shovel; the auger will make a pipe-size hole, but the wider shovel hole will require that soil be tamped around the well point to help hold it straight when pounding. A PVC casing placed over the well pipe but kept above the point so that it doesn’t inhibit water flow keeps loose dirt from falling in around the well pipe as it is driven downward. more
When you reach the water table you will hear a hollow “bong” sound that issues from the pipe with every blow. To test it, remove the cap and drop a long string with a weight tied to its end (chalk line works well) down the well pipe until slack in the string tells you that the weight has reached the bottom of the well point. Draw the string back up, and measure how much of its length has been wetted to determine how deeply the well point has penetrated into the water table. To ensure good suction at the pump, it is important that the entire length of the perforated well point be immersed, and preferably at least two feet beyond that to account for seasonal variations in the water table.

When the well point has been driven down until only about ten inches remain above ground, remove the protective pipe cap and screw a four-inch coupler (a collar with internal threads) over the exposed threads. Use pipe joint compound or Teflon plumber’s tape (wound in the direction of the threads, clockwise) to ensure a watertight seal. Screw a 6-foot-long pipe that is threaded on both ends into the coupler actual length of the pipe can vary, but it has to be short enough to reach the upper end (you’ll probably want a stepladder). Cap the upper end of the pipe, and pound it down until only about ten inches remain above ground. Remove the cap, apply joint compound to the threads, and screw-on another coupler, then screw another length of pipe into the top of the coupler. Pound this pipe down, and repeat the process, making sure to seal every threaded connection with joint compound or Teflon tape. [links]
