Concrete is an excellent permanent building material that provides weather-resistance and extremely heavy-duty surfaces when needed.

However, these advantages are exactly what makes it so difficult to cut when it needs repair or replacement.

For optimal results, selecting the right concrete cutting tool for this application is as important as matching the right blade to the material that needs cutting.

Concrete Saws

A concrete saw, also known as a road saw, slab saw, cut-off saw, or quick cut is the most commonly used power tool to cut through concrete, brick masonry, tiles, asphalt, and other solid materials.

Walk-Behind Saws

The ultimate in multi-purpose cutting tools, walk-behind saws are designed to handle tough concrete and asphalt cutting projects.

They come in many different types including push saws, green concrete saws, and self-propelled saws that travel forward powered by the saw.

  • Push and self-propelled saws are available in power options that range from electric to gas, diesel to hydraulic and even air pneumatic power.
  • Slab Saver Concrete Saws are designed for the tough demands of decorative, control joint, and demolition sawing with pinpoint accuracy.
  • Flat Saws are simple tools engineered for DIY operators as well as professionals to cut through flat slabs of concrete.
    • They are highly durable and deliver quality and accurate sawing of horizontal flat surfaces in a multitude of different applications such as pavements, bridge decks, and concrete floors.
    • Flat saws, also known as slab saws, come in electric or diesel units that can cut through anything from driveways to runways, hard tiles and even very dense materials such as stone.
    • Flat sawing uses the diamond cutting method that features a diamond blade mounted on a walk-behind machine operated by a single person.
    • They can cut to a depth of 24 inches and are typically used for the following applications:
  • To provide expansion joints
  • To remove damaged sections in pavements, driveways, and other surfaces
  • To clean and prepare cracks for repair
  • To remove large concrete sections for demolition purposes
  • Pro Slab Saws are developed to deliver exceptional performance in larger cutting applications and tough concrete sawing tasks.

Concrete Cutting Blades

These powerful concrete cutting tools are commonly used by contractors to cut through concrete surfaces or to cut up roads.

They use diamond blades as a significant amount of friction is generated when cutting through hard substances.

Large amounts of water are normally required to cool the blades, reduce silica dust, and prolong the life of the diamond blades.

Durability and high cutting speed make diamond blades suitable for most concrete sawing applications ranging from heavily reinforced concrete to asphalt.

Diamond blades are suitable for equipment that ranges from large diesel-powered machines to small electric units and are designed for applications such as slot cutting for electronic or electric cables for installation of traffic loops.

They are also commonly used in joint widening applications.

One of the best benefits of diamond blade technology is the speed and smoothness with which diamond blades can cut through all types of materials, especially construction materials such as heavily reinforced concrete slabs.

Innovative technology in the design provides improved cutting speed through reduced lateral friction, improved dust evacuation, and better cooling abilities.

The properties of diamond blades are determined by the machine to be used, the application, and the material that needs to be cut.

That is why it is important to choose the right quality for the performance required and are normally divided into different levels for each type of cutting job.

Important Characteristics of Concrete Cutting Saws

Concrete cutting saws by their very nature should be reliable, easy to start, and extremely powerful to enable them to work in the toughest conditions, in harsh climates, and with different fuel variations.

Lightweight models are best for general contract or patchwork jobs whereas heavy-duty diesel propelled models are better for professional cutting jobs such as highway roads and pavements.

Walk-behind concrete saws, push saws, and self-propelled concrete saws can be used for a wide range of applications from small projects to large demolition projects.

Which one is suitable for your requirements will depend on the size of the project, the thickness of the material to be cut, and the speed and accuracy required? You may also opt for a specialist concrete cutting company like Megasaw who uses only the best practices to get the job right.
