Do i have to pre soak these to have them work or do I just put them out before the rains start?

I learned the hard way that if the rain comes hard & fast, then you should have pre-soaked them. If it falls slow, then maybe the bags have time to swell.

How much do they weigh after they have been soaked in water and fully absorbed?

Thank you for our interest in the Sandless Sandbags. Each bag will absorb 4 gallons of water and weigh 32 lbs. If there is anything further we can assist you with please let us know.

What is the best placement to prevent watering from coming through the garage door (inside garage, outside, or both)?

Block/divert the route of the water. The pavement outside our garage rises with frost, so we pile bags on corner outside of door & also inside. Our condo assoc. refuses to pay to have the concrete lowered ( another reason not to buy a condo ), so every snow ice thaw we have a flood in our garage.

do they stay in place in a hurricane

We pre soaked ours to make sure they would stay put when the wind started
