I have a cinder block home built in the 50's. During heavy rains, I find water leaking in between the cinder block and the slab foundation it sits on. Is there a good fix for this? Is there a fix I can do myself?

I think you would be putting a band aid on a bigger problem. Incorrect slope of the ground away from the foundation - gutters not moving the water away from the foundation - perimeter drain lines that were installed but have become clogged. Do you have a sump system?
It would not be a bad idea to have the break between the slab and wall power caulked. We did it for radon reasons. But - if you do that and don't correct the water problem - pressure may build up under the slab and crack it.
First check all grades and gutters/downspouts.
The best way to deal with that is not caulk shut the slab floor where it meets the block foundation. Its better and easier if you redirect the water
Cut the concrete floor about 4"out from the foundation wall. remove that 4"section on the perimeter of the wall and make it into a trench. Get some 1 1/2 PVC pipe and drill holes in it about every 4" and the more the merry. Lay the pipe in the trench and fill around it with rice mix stone. Pour the last 1" or so of concrete and finish up to foundation edge.
Install this and run the pipe to the sump pit.
If the water is real bad cut concrete trench wider and use black perforated pipe that you see on a roll and use that to get to some. That also needs stone around it.

... I should have said it only happens during hurricanes or severe tropical storms like Faye this past September when we got 26 inches of rain in a 24 hour period.Quote:

Tipaine999 You got to be kidding me. Okay if we can solve thins problem for you in under $450.000.00 Can we get the Royalties? I might be able to do it for that.Quote:

Tipaine999 If all you get is a little bit of water in the basement after over and Inch of rain per hour in a 24 hour period then count your blessings.
Not to bust your chops here but what did think the (... I should have said ) wasn't important here?
Trench the floor edge and use the 4"pipe and two sumps in new pit and discharge the pipe WAY out from the house. Rate the sump pumps to 1inch of rain in gals for discharge capacity from the ditch width and depth.

I don't have a definent answer, but it is obvious that most of the people answering the question don't know anything about cinder block on a slab construction (like found in Florida). Unless I missed something I did not see any mention of a basement? I live in Florida and have the same problem. I have graded the yard to drain away from the house. I have installed gutters with long runs away from the house. I have seen advertised and plan to try United Gisonite Lab 27512 Drylok Latex Masonary Waterproofer. I hope this along with the other steps I have taken will keep the moisture out during a huricane.
