Here it is, the hammer of your dreams.  Just jetting or pushing your pilings in doesn’t give your dock or boatlift the support it needs, especially boatlift pilings.   They have a tendancy to sink under the constant pressure of a boat.  But if you drive it to refusal  you will avoid the hassle of re-setting piles.  This video is just around 6 minutes, you can see the movement of the piling moves pretty fast at first, the bottom was a sand – shell base.  I jetted the piling in place so it will stand on it’s own approximatly 7 ft. then hammered to refusal another 4 ft.  This hammer is 640 lb.  and was running at 60 psi.   I can make them lighter or heavier depending on your needs.
