When I installed the sheathing on the walls I placed them so that about a foot of the concrete foundation was also covered. Now ordinary nails just don't do concrete so I needed another solution to secure the sheathing material to the concrete.
I used a tool called the the 'Power Hammer' made by Remington - Yes the rifle people, to literally shoot nails through the sheathing and into the concrete. This power hammer drives special concrete nails ranging from 1 to 2.5 inched in length using a .22 caliber, necked down, crimped, low velocity power loads.

It is very important to use the right length of nail and power load combination. The power loads come in 4 strengths. I used 1.5 or 2 inch nails with the highest power load, a number 4 which were colour-coded yellow.
