   I have been told the polyurethane (from Sika, also sold as radon sealant) you   
   squeezed from the inside into the outside towards the inside using "ports"   
   works really well.  I was planning to use it.   
      
   But I did a quick fix of putting three bricks under the crack as a well to   
   hold the water (and a tube to take it to the drain). I attached the bricks   
   using a slather of Loctite PL polyurethane and the area around the bricks has   
   been wet a lot longer than without any sealant (ie the bricks just sitting   
   there waiting for project). Now I applied the polyurethane about 12hrs before   
   the rain leak, and polyur sez 1 wk to cure, and they say it bonds better when   
   wet. So in a week, will it be waterproof?   
      
   Some folks insist elastomer or silicone are preferrable.  So, I'm tempted to   
   put a dab of sealant on a small piece of tubing and some dye on the other   
   side and compare the sealants side by side.  But I wanna know the real   
   underlying experimental variables in order to do that right.
