Concrete slab sawing is the process that turns existing concrete into an even flat plane by cutting the surface layer. This technique is used to level damaged pavement, provide control joints or lay underground wires and pipes. When it comes to slab on grade, structural decks, roadways and any other horizontal surface, concrete slab sawing gets the job done.
Concrete slab sawing is a way to generate joints in concrete. Concrete saw cuts should be done at a predetermined spacing to control cracking due to shrinkage. It is important to cut concrete after it has obtained enough strength to keep it from raveling but before cracks could be initiated internally. The timing of concrete slab sawing is essential to avoid cracks in concrete before cutting. Determining when to saw cut concrete depends on the type of admixtures, temperature, mix design and aggregate type.
Concrete saw cutting timing depends on several factors such as hardness, blade type, weather condition, concrete mix design and aggregate size. Starting concrete slab sawing too early could cause raveling, while sawing too late will result in uncontrolled cracking. Under hot weather, concrete saw cutting should start after an hour depending on how the concrete is reacting.
Our saw operators perform trial cuts to determine if the it’s time for concrete slab sawing. Saw cutting should start as soon as the raveling stops during these trial cuts. If the slab of concrete is too large, we have multiple saws to work in several areas at the same time. There are several types of saw blades that can be used depending on the concrete used and how fast these cuts could be started. Fine Cut’s slab saws are powered by gas, diesel, electric and hydraulic.
Our concrete slab sawing trained operators are equipped to cut through concrete, structural concrete, stone, brick, cinder block and asphalt. Fine Cut is located at 19415 S. State Route 7, Pleasant Hill, MO. For more information about concrete slab sawing and our other services, call (816) 540-5787.
