Fellows I need some dock help/advice.
My brother has a nice dock on Lake Fork
in East Texas, but age is taking it's toll.
The dock was built 25 years ago using steel
piping for supports before the lake was full.
Now the Lake is low and we discovered some
serious problems with the support structure.
The water and elements have really taken a toll
rusting out the support beams. Does anyone have
any experience on the possible best ways to repair
something like this? See pics below:
Here is the dock years ago when Lake is full:
Here is the new aging problem with the metal pipe supports.
