spotted the first damp spot

We're currently building on a walkout basement. Poured concrete walls. About 50% of walls above grade. The walls were sprayed with "mastic" and covered with "shockwave" drain board. They also used an egg carton looking channel drain that pipes out to daylight.

The foundation was poured back in early February and we've kept a close eye for damp spots since.

This weekend we had a good soaking rain and we noticed a spot about the size of a pack of cigarettes that was damp. It was right where the wall meets the floor. The basement has otherwise not had a single sign of dampness.

How concerned should we be? would a dehumidifier keep this sort of stuff in check? should I not accept it and insist that they dig out the soil and re-apply all waterproofing?

Thanks.
