What’s Included

Builder Tips:

Request saw-cut control joints to prevent cracking. If planning radiant heat, tubing must be placed before pour. Garage slabs often slope slightly to the overhead door — verify this with the flatwork crew. Clarify if your bid includes excavation/gravel prep or if your excavator is handling it.
