Airplane Hangar floor -Help!!

[A35Plt]

Hello Everyone!
I have an airplane hangar that is bolted to the ramp out at my local airport. The building is roughly 35x35. The ramp is 20 year old asphalt. The asphalt is cracked and incredibly dirty. When it rains the water pushes up through the cracks in the floor. I have sealed all around the perimeter of the hangar with crack sealant so no water comes in under the walls. But the water coming through the cracks in the floor keep the hangar damp in winter. It's rusting my tools and causing corrosion on my airplane parts.
What can I do?
My options were:
1. Concrete a pad and set the hangar on it or concrete the floor inside- This is really NOT an option for several reasons, financially and (most importantly) the airport would not agree to my doing this.
2. Having the building moved to a concrete ramp- Already been turned down on this by the airport management.
3. Possibly sealing the floor and floor cracks with some sort of sealer (Epoxy?) and putting tile on top of that for a more finished look.

So, #3 or some variation of that plan is all I can think of. Does anyone have any better ideas or can anyone recommend any products to use? Has anyone here dealt with a similar problem? Thanks for the input.

I'd rent a tar pot and seal the cracks with a hot pour pavement sealant.

Pics would help as I am having a hard time envisioning the floor structure.

If you are sure that no water is coming in to the hanger from under the exterior walls, then it sounds like the water table is literally pushing upwards through cracks in floor. ....

Sealant will help, but as the water table pressure rises, the water will come up in a path of least resistance somewhere, a new crack or wall gap. Ever check the outside of the building to assure water is not literally draining under your hanger ?

Agreed. If the floor is worth saving, we have a tar based epoxy.
I would do a test area before doing the entire area. Post some pics so we can see how bad this is.

Thanks for the replies. Can't post pics right now because I am in Afghanistan for the next few months.
I think basically the water is getting between the old layers of paving outside through cracks, and then pushing out again through the cracks in my hangar floor.

Seems like the only real answer is to seal it, but I question whether that's even possible, like Greg says.

Racedeck and such will keep your feet dry but won't do anything to keep the humidity level down and stop the tools rusting or parts from corroding. I'd talk to the Legacy folks and see what they think, but I think you'll need someone on-site to really evaluate whether the sealant would stick and do what you want it to.

I dont know which is cooler...
The plane, the floor or that shiny belt-buckle!!

It sounds as if this is a Port-A-Hangar that is essentially a portable building staked down to an asphalt ramp. If this is the case, the OP is stuck with the situation and will need to seal the asphalt cracks and probably put a seal coat on the whole thing.

Hi Charles, Yes it is a Port a Port and at this point I'm thinking of just flooding the floor with epoxy floor paint- It will go into the cracks and hopefully seal it. Located at KLZU between Atlanta and Athens.

We had the same problem when the airport athority put T-hangars on an existing ramp and rainwater would get into the hangars under the doors and walls They tried everything to block the water from getting in, but the eventual solution was to put drain grates around the outside walls and door of the t-hangar buildings to keep the rain from getting in. I've heard it is worse to keep your plane in a humid hangar than it is go tie it down on the ramp.

Does race deck keep the water out of hangars to help control humidity???

OK, this is driving me round the bend! Someone name the aircraft please.

That looks like a Navion to me.

A guy at our local airport had one that was converted to a twin.

Google IWC Sealcoating, they are in Knightdale,NC. See if they are going to be down your way sometime and get them to spray he place.

Is there any grade out the back of the hanger? If so, I'd rent a concrete saw and cut about 18-24" toward the slope. Fill it with Stone and a drain pipe. Repair the concrete and seal the floor. Giving the water a path away is the best way to make the sealant hold up. So I guess the question is, what is out back of the hanger.

Jackfre,
About 36 inches behind the hangar is...another hangar.
I am going to call a concrete guy just for grins to see what it would cost to put 2 or 3 inches of concrete down. Other hangars on our row have done it in spite of the county and they look very nice with no water at all...
I may have to jack the hangar up several inches and let them pour the concrete underneath. Otherwise I'll be gluing the hangar there permanently.

I spoke with Ray from IWC SealCoating yesterday, He's actually going to down in Georgia in the next few days/weeks doing some place down there. You might want to call and talk with him to see if it's in your area.

Yes, that an old Navion. It was a nice airplane and there aren't that many of them still flying.

This hangar happens to be former Senator Jake Garn's personal hangar. I also believe the space shuttle photo is of the one he flew in.

"High and dry" is always the best move. I also think that the concrete would be easy to break up and haul away if you ever remove the hangar. 4" don't sound like a big incline, but depending on the size of your plane, you may want to get a small tug.

when i did construction on new homes up north all the basements had a drainage channel between the slab and the wall. this channel terminated in a sump pump pit and from there it was pumped outside. it maybe be easier to move the water then seal the slab
