Soft spot on floor.

[vetplus40]

Greetings, my 32 foot Sierra Select has developed a small soft spot in the kitchen floor. It's not in the area where you stand to wash dishes, but in the area where your foot lands when stepping down from the stairs to the bedroom. I have checked and cannot find any evidence of a water leak. Is it possible that the plywood floor has become delaminated from the body weight of stepping down on the floor over several years? The spot is about 8" inches or so in diameter.
As usual, thanks for any insight.

Hello, and sorry for your issues. First you must find out what the substrate
otherwise known as the floor is made of. This will dictate the repair procedure. If floor is honeycomb then there are injectible products to inject into the floor in order to stablelize the floor. If the floor is made out of wood you will need to remove the bad wood and replace with new wood. Either way the tile will need to be removed in order to repair. Good Luck.

Thanks for the reply. I'm not sure what material the floor is made of. It will have to get worse before I rip up the linoleum flooring and replace it.

Thanks for the reply.

We had an issue similar to your issue. Come to find out, it was the cold inlet to the water heater had cracked and was leaking, the water was running all the way across the rig to the other side.

Had the same problem on my previous 5ver.

Discovered two things when I pulled it up.

1. When building the unit they cut thru the floor joist to run the heater duct.

2. That would have been OK if plywood decking had been used. The OSB just gave up over time with my 250 lbs of coon-ass landing at the same spot.

I made a composite floor joist out of glued & screwed ply that allowed the duct to pass thru and still give a lot of support.
