Cutting too early can mark the pavement surface as well as cause joint raveling. Late sawing can result in random concrete cracks. Shallow cracks aren’t sufficient to prevent uncontrolled cracking while deep cuts are excessively labor-intensive and undermine the aggregate interlock in the concrete. Once cutting starts, it has to continue until the joints are finished and before the concrete surface temperature begins to fall. Stop the saw cut 1/2 inch before the edge of the pavement.
Why You Should Cut A Concrete Driveway After You Pour A Driveway
Before we start, it is important to know what a Concrete Driveway is ? Concrete is versatile, durable, low maintenance and indicates quality construction right at the first glance.

Now, the real question is – why should you cut a concrete driveway after pouring a driveway?
Saw-cuts are used to cut concrete driveway. They are also used to create control joints in concrete which helps in preventing cracks occurring due to shrinkage. The perfect timing of cutting a concrete driveway is crucial. There are many factors which decide the timings of a saw-cut.
In hot weather conditions, saw cutting starts as soon as four hours after the concrete is poured and if it is in cooler weather, saw cutting may not even start for 12 hours after pouring.
If you want to determine whether the slabs are ready to cut to check for raveling, start saw cutting as soon as the raveling stops.
The reason you should cut a concrete driveway is that concrete tends to shrink a bit after getting dry. This will result in cracks. So, to avoid these cracks, it is better to cut a concrete after you pour a driveway, A few other potential reasons are :
- The lines are cut to help in providing sufficient friction to user’s.
- The lines are cut to provide a rough bonding surface for any coating or toppings.
- The concrete driveway is also cut, if concrete is continuous then these lines help to curb the shrinkage cracks.
The main purpose of cutting a concrete driveway is because concrete shrinks as it cures. The lines which are cut, give the concrete a place to develop the fine shrinkage crack and that remain unseen.
Control joints should be sawed as soon as the concrete can withstand the energy of sawing without raveling or dislodging aggregate particles. In most of the concrete work, concrete cutting should take place within the first six to eighteen hours and never it should go beyond twenty-four hours
If the weather is hot, and you fail in cutting concrete on time, you might end up getting cracks in them.
Keep one thing in mind, the cut in concrete should be made at a predetermined spacing and only after the concrete has gained sufficient strength. Don’ t end up waiting for so long because if not done at the correct time, you might get cracks in concrete.
