Preventing Boatlift from Damaging Lake Liner

[jipster43]

We are looking at installing a boat lift at our ski lake but are concerned that the feet will compromise the bentonite liner and cause a leak. Or it may just sink in the clay and be a bugger to remove when the ice begins to threaten. Do any of you seasoned experts have any tips for installing a boat lift in a lake with a bentonite liner?

 

Gracias!

Plastic wheels options possible on your lift ?

You could bolt 2''x10'' wood planks to the feet of the lift. I have them bolted to mine. It makes it easier to move. They sort of act like skis.

No experience, our lake is sand and 4-15" rock where the lift sits. I'm usually struggling to move rocks enough to get the lift to settle even on all 4 legs

You could use a hydro-hoist lift system. We used one in Indiana on an Army Corps Lake that would not allow anything to touch "their lake bed". We used a floating dock with the lift. Worked great. MWN

On my lake, we don't have a liner to worry about but there are a lot of areas with clay that makes sinking and getting stuck an issue. many use 24" x 30" precast patio stones under the feet of the lift. They create a large increase in surface area and they are cheap, last a long time and can remain in the water year 'round.
