effloresence
 
I know that it means there is some amount of water seeping through the wall, but the wall is never actually wet. My question is, is the fact that there is effloresence on a block wall in my basement a sign that something is structually wrong or will it lead to structual damage?

Efflorescence is generally only an appearance issue, but it DOES indicate a problem with water infiltration on older construction. That is, it is common and not an issue on something newly built, but if it appears on something built long ago, there is an issue.

Would bring in dirt to add a better slope away from the house help to fix this problem. It is fairly flat now or slopes even slightly toward the wall. I planned to bring in dirt to go from about 12 inches over 10 feet or so. If not, On older homes where this is happening, is putting weep holes to drain the block cores enough to prevent any structural damage?

You won't live long enough for it to structurally damage the wall (the efflorescence), but grading the dirt away from the wall should help the water infiltration (which could destroy the wall).

So the water infiltration would eventually cause probems but would take forever? Or the water infiltration could damage it soon but the effloresence itself wont damage it?

Efflorescence is a symptom of water infiltration. Efflorescence does not generally damage the wall, but the water infiltration does.

so I guess my question is, is this something I need to be corned about? Thanks again.

You need to be concerned about the water infiltration.
