Company: “Heritage Slag Products, L.L.C. came
to the Illinois market several years ago to produce steel
slag. We employed CTL for our Quality Control testing needs.
We were very pleased with how dependable they were on test
turn-around, and their knowledge of ever-changing specifications
in the aggregate producing field is outstanding. CTL has also
been a great help with keeping an open line of communication
between industry and state. We would highly recommend them
for any Quality Control needs.”
