had this to say:
Bought gravel from this company. They did an excellent job in delivery and spreading the gravel as they dropped it. Will definitely purchase more from them in the future.

had this to say:
Blazek corporation just completed our wastewater treatment plant upgrade and things couldn’t have gone better all completed within the expected time frame. I hear some of the horror stories other cities experience with other contractors and realize how very lucky we were to have Blazek as our contractor.
