Floor sawing, also known as slab sawing or road sawing, is a specialised concrete cutting technique that uses self-propelled saws equipped with diamond blades to cut through flat concrete surfaces, such as floors, slabs, or roads. The process allows for accurate, clean cuts to a significant depth, making it ideal for various construction projects.

Purpose of Floor Sawing:

  1. Creating expansion joints to control cracking due to concrete shrinkage
  2. Removing damaged or unwanted sections of concrete
  3. Cutting openings for utility lines, such as plumbing or electrical conduits
  4. Demolition purposes, allowing for the easy removal of large concrete sections

Tools Used in Floor Sawing:

Floor saws, also called road saws or slab saws, are the primary tools used in floor sawing. These self-propelled machines are equipped with powerful engines and large diamond blades, allowing them to cut through thick concrete surfaces efficiently. The depth of cut depends on the blade size, with some floor saws capable of cutting up to 500mm deep.

Floor Sawing vs. Other Cutting Methods:

Compared to other concrete cutting techniques, such as handheld sawing or wall sawing, floor sawing offers several advantages:

  1. Precision: Floor saws create straight, clean cuts with minimal irregularities.
  2. Efficiency: Self-propelled floor saws can cover large areas quickly, saving time and labor.
  3. Depth: Floor saws can cut significantly deeper than handheld saws, making them suitable for thicker concrete slabs.


Applications of Floor Sawing

  1. Road and pavement repairs
  2. Bridge deck maintenance
  3. Airport runway construction and repairs
  4. Warehouse and industrial flooring
  5. Parking lot improvements
  6. Foundation work for new construction projects





Frequently Asked Questions:

  1. Is floor sawing related to diamond drilling?

    While both floor sawing and diamond drilling use diamond-tipped tools to cut through concrete, they serve different purposes. Floor sawing is used for making linear cuts on horizontal surfaces, while diamond drilling creates precise, circular holes.

  2. Can floor sawing be used to cut materials other than concrete?

    Floor sawing is primarily used for cutting concrete, asphalt, and other masonry materials. For cutting other materials like metal or wood, different specialized tools are typically used.

  3. Are the blades used in floor sawing made of real diamonds?

    The blades used in floor sawing are usually impregnated with synthetic diamond particles , which provide the necessary hardness and abrasion resistance to cut through tough materials like concrete.

  4. How can I find professional floor sawing services in London?

    To find reliable floor sawing services in London , search for reputable concrete cutting companies with experience in the field. Look for companies with positive reviews, proper certifications, and a strong portfolio of completed projects.
