been out of that trade for a while, if i remember correctly, there are different kinds of joints for concrete. theres expansion joint that you can put in between, i think theres some kind of metal u can put in between, and you can also run a cutsaw across to make the joints. (control joint, cold joint, etc) control joints keep the cracks from spreading i think. haha . I dunno how it works for a drag strip though. i need to get some VHT from summit so i can prep one end of my driveway and practice my launches
