Houseboat

[captchaz]

I been reading the other threads on this and I'm about to start building my floating deck to put a portable wooden building 12ft by 20ft,building weighs 4,000lbs. Deck will be 16ft by 24ft. I have drums but they want 6000$ to fill 50 drums with foam. I hear people using foam 2ft by 2ft by 16ft. My question is how long will it hold up in salt water? And also if anyone has a houseboat built out of drums or foam how high does the camp sit out the water?

Unprotected foam won't last long and drums seem to attract idoits using them for target practice. You'd be much better off to spend a lil extra and buy or build some steel or aluminum pontoons.

Wouldn't the drums rust in saltwater? Is that price for closed cell foam?

If it is saltwater, please don't use metal drums. Dat's bad.
It all depends on the bouyancy and density of the foam.
And it can't be open cell foam, it will absorb the water and sink lower in the water.
I see people using those white styrofoam floats used for laying pipelines across marshes. Not sure where they get them from. They hold a lot of weight.

If I were you, I'd try to find an old party barge. Replace any rotten plywood decks and paint the pontoons with a barrier paint. It will probably last longer and be cheaper.
There gots to be one somewhere that someone is wanting to get rid of cause of rotten floors and/or burnt up motor. The toons and framing are all aluminum. Should last a long time.

I would like to find a old pontoon let me know if someone comes across one 28-32 foot.

The drums are plastic I work offshore and been keeping them. I seen someone had a camp with drums and never noticed if they were filled. I figured the foam would last way better in freshwater than salt water.

Lots of butterfly barges are made with foam filled plastic drums and styrofoam pipeline bricks. Styrofoam sometimes breaks up in bad weather. Drums leak around bungs. They build them so that if one or two get loose, it won't turn over. Check out the butterfly barges around your area if they have them.

You can buy 2 part closed cell foam and do it yourself not sure where you can get it I am restoring an old boat and that is what I am going to use

You can get it at West Marine in bulk. May have to order it online.

It's cheaper if u have a large amount like 50 drums to call someone who does spray foam insulation . Tge closed cell does not expand nearlyH as much as open cell does

I will read up on the 2 part foam. I also thought about getting the foam blocks and glassing a box around them.

The person I talked to didn't say which one it was just gave me a price I will call back Monday and find out which one it is. Which one is better?

I just talked to my uncle. His buddy has been building a house boat for the past couple years. It is parked in Mermentau near the bridge. He used plastic drums and they are standing vertical with the bungs straight up, no foam. A few of the drums are kinda dented looking, I guess from getting bumped. He built a few seperate sections like this and put them in the water then attatched them. Not sure how he fastened them together though. He has a solid layer under it of drums, if some one were to shoot a few it would still float. I still would go with a barge or pontoons of some kind. My 2 "sense"

Johnson fiberglass supply in Houston has the 2 part foam mix, it's not near as expensive as you were quoted and they will ship it. or if you decide to use the styrofoam blocks they have the mat and resin to seal them or you could have a fiberglass shop chop shoot them. most of the floating cabins in south Texas LLM are floating on glass covered foam.

Closed cell! It cost more but will not absorb water and is Rick hard when dry

[fishinpox]
