twodog Posted August 30, 2021 Share Posted August 30, 2021 I have the normal spongy floor in my 91 Warrior I removed the carped, and there doesn't seem to be any rot that is visible. I was wondering if anyone has had any success drilling holes in a 6 inch grid pattern and injecting epoxy . I have seen a couple of videos on you tube on this, but just not sure how successful this is. Thanks for any help Quote Link to comment Share on other sites More sharing options...
MaineJed Posted August 30, 2021 Share Posted August 30, 2021 Get underneath the coach and look up to see where the wood is punky Quote Link to comment Share on other sites More sharing options...
Ctgriffi Posted August 30, 2021 Share Posted August 30, 2021 Warrior floor will never be rock solid, IMO: it has a light sheet-metal underbelly welded between the frame rails, with foam board on top, and a final layer of thin ply. I think it's reasonable to expect some flex. Long as the sheet metal layer is intact and not loose, you should be okay. Quote Link to comment Share on other sites More sharing options...
neilp Posted August 30, 2021 Share Posted August 30, 2021 My '93 Itasca Spirit (same as Warrior) has the spongy floor issue. If I look underneath it is in great condition but still feels kinda soggy when you walk near the stove / bathroom door area (rear bath floor plan). I've thought about adding some stiffening underneath between the frame rails. Maybe some angle iron that is notched to sit on top of the frame on each side. One day I'll find the time to give it a try! Quote Link to comment Share on other sites More sharing options...
WME Posted August 30, 2021 Share Posted August 30, 2021 I think I remember someone drilling a grid on the floor and epoxying in wood pegs (dowels). Said it make a big differance Quote Link to comment Share on other sites More sharing options...

john*thomas Posted August 31, 2021 Share Posted August 31, 2021 Interesting topic. I'm 98% sure I have all my leaks stopped. Next to address was going to be the floor. I see where a few mention a bit of spongy areas but what seems to be a pretty solid floor. I've been under mine and have poked around and it seems pretty solid. I suppose I'll find out before long. I'm putting waterproof laminate flooring down in our bedroom/bathroom and I hope to have enough left over and pieces to do the RV. Quote Link to comment Share on other sites More sharing options...
Big Rolling Turd Posted August 31, 2021 Share Posted August 31, 2021 As previously mentioned, the "sponginess" is a result of a lack of support for the floor. I did the epoxy process and it works wonders. Quote Link to comment Share on other sites More sharing options...
twodog Posted August 31, 2021 Author Share Posted August 31, 2021 I'm thinking about the epoxy route. just don't know how deep to drill. does anyone know? Quote Link to comment Share on other sites More sharing options...
jjrbus Posted August 31, 2021 Share Posted August 31, 2021 My floor was intact and not rotted in anyway. It did have some flex when walking on it. I looked all the options over and added a cross brace underneath in the middle of the flex area. Worked well. Quote Link to comment Share on other sites More sharing options...
