hi,
i just thought of a project in my garage to put up a 2ft high ramp to elevate the family car (innova). given historical information and experience, i think 2ft is enough to elevate the vehicle. in the long run, its not just for flood prep, but also for some of my underchassis maintenance work.
i am thinking of putting two parallel ramps made of concrete (i need the center space).
any ideas? gotchas? or things to beware?
afaik, concrete can take the whole weight of the vehicle and not crumble right?
do i need hollow blocks here or metal reinforcements? gravel?
thanks
Re: 2ft car ramp (flood preparation)
Just sharing..i want to share a noble idea ive seen my brother`s friend house a year ago in dampalit malabon..we all know flood was common in malabon..Years back almost all his car were fitted with semi stainless thin plate unfortunately the car was too heavy for a trip to baguio LOL and gas consumption was also a problem..But what caught my attention was his design of his garrage..it consist of 6 poles fitted with ring attached to a flatform..The flatform were consist of plates with styroblock from from styro plant in sta.maria bulacan about 24" thick-2 block atop each other thermal sheet then metal plate were welded together..What is amazing to this was whenever a flood rise the flatform with car on it also rises .The initial problem was imbalance of weight making axial force in each pole making it hard to go up..Solution were made was to put axial bearing to make the flatfom evenly rise up as the water level rise up..But in the end rust prevail..a nice idea if he puts stainless pole instead..

Do you mean something like the car wash ramps in gasoline stations? Concrete made.

Yes it could be like that. From where I live, the petron station here have a concrete ramp waist high used for undercoating.
In my case I just need 2ft high.

If you want it permanent then maybe concrete. If removable or collapsible then probably metal is the way to go.

Re: 2ft car ramp (flood preparation)
But what caught my attention was his design of his garrage..it consist of 6 poles fitted with ring attached to a flatform..The flatform were consist of plates with styroblock from from styro plant in sta.maria bulacan about 24" thick-2 block atop each other thermal sheet then metal plate were welded together..What is amazing to this was whenever a flood rise the flatform with car on it also rises .The initial problem was imbalance of weight making axial force in each pole making it hard to go up..Solution were made was to put axial bearing to make the flatfom evenly rise up as the water level rise up..But in the end rust prevail..a nice idea if he puts stainless pole instead.
Got any pictures? Is it still working?
Looks like pier design can get complicated, e.g.,

Maybe simpler not to bother with sliding on piers and just tie the thing with ropes?

Anyone know of other local examples of floating houses/garages? I wonder if anything happening, any ideas, in Philippine architecture community, on floodproof structures.

Out of curiousity, how much styro would you need to lift a 2-ton vehicle?
Is there a known ratio on how much load a styro can lift?

A cubic meter of water weighs 1 ton (heavier if its saltwater). To float a 2-ton vehicle you need to displace more than 2 cubic meters of water.
Therefore you'll need more than 2 cubic meters of styro. Also consider the weight of the frame/styro/etc.

Or you may use empty plastic drums just like how they use it in floating fish ponds. Better material, available and easier to use

yeah, but between styro and hollow plastic, when styro breaks, it will still float, but when the hollow plastic breaks, it will tend to sink

How about a styro filled hollow plastic? Unless the styro is strong enough without a casing or something to hold it in one piece when under load?

I do agree with that SG but you need quality styro to float efficiently. The normal styro that you could buy at book stores doesn't cut it. It should be the dense type used in appliance packaging and in styro coolers (usually used by ice buko vendors)

Problem with this Jay is that the styro will consume the airspace thus will affect the buoyancy of the drum as compared to a sealed and air filled one.

There is a known principle ... Archimedes' principle ... and it is not specific to styrofoam. If you want a ratio, it is 1:1. To float something weighing x requres displacing a volume of fluid weighing x. Displacement can be done with anything ... styrofoam, hollow plastic, solid plastic, plastic filled with air, filled with styrofoam, wood, boat hulls.
Previous estimate is right. To float 4,000 lbs, need to displace a volume of water that weighs 4,000 lbs (~1,800 kg). Assuming water density is ~1,000 kg/cu.m, this volume is 1.8 cu.m.
Hard to imagine that just 1.8 cu.m of water hitting you in a tsunami, in terms of mass, is like a 2 ton car hitting you.

Anyone with ideas on how to go about a metal frame? I'm not much into metal fabrication but getting there. I'm after the stuff that deals with structural and redundancy.
