Drilled cellar floor - dark stuff?

Doki · 2006-10-04T23:21:13+00:00

I drilled my cellar floor the other day to fit a ground anchor. After an inch or two of concrete, I hit a much darker coloured substances that seemed easier to drill. Any ideas on what it is and if the ground anchor's going to be held in well?
