A Comprehensive Guide to Concrete Hand Sawing

By admin In Industry



Concrete hand sawing is an essential technique for anyone involved in construction, remodeling, or renovation. This process is necessary to make precise cuts into concrete material, such as walls, floors, slabs, and pavements. Hand sawing is preferred over other methods of cutting concrete because it’s cost-effective, efficient, and produces minimal dust. 

In this guide, we’ll explore everything you need to know about concrete hand sawing, including equipment, types of saws, blade selection, cutting techniques, safety guidelines, and more. 

What is Concrete Hand Sawing? 

Concrete hand sawing is a method of cutting through concrete using hand-held saws. It provides precision and flexibility when working with concrete, allowing for intricate cuts and adjustments.

Why is Concrete Hand Sawing Essential? 

Concrete hand sawing offers several advantages over other cutting methods. It allows for greater control, versatility, and the ability to work in confined spaces where larger machinery may not be feasible. Additionally, hand sawing enables precise cuts and minimizes the risk of damaging adjacent areas. 

Equipment Required for Concrete Hand Sawing 

To start with, you’ll need some essential equipment to get started with concrete hand sawing. These are:

  • Safety gear: goggles, earplugs, dust mask, gloves, and hard hat.
  • Hand saw: a manual tool that requires physical force to operate.
  • Diamond blade: a circular saw blade with diamond particles that cut through the concrete.
  • Dust control system: a vacuum or exhaust system to trap the concrete dust.
  • Concrete marker: chalk, pencil, or spray paint to mark the cutting lines.

What Type of Hand Saw Would be Best for My Needs? 

Choosing the right hand saw depends on several factors. What are you planning to cut? Is it in an open area or a confined space? Do you have access to electricity and water? Additionally, how deep do you need to cut? 

Let’s explore the different types of hand saws to help you make an informed decision:

  1. Two Stroke Demolition Saw: This saw is powered by a two-stroke fuel mixture of petrol and oil. It produces a significant amount of smoky exhaust and is quite loud. Due to the need for ventilation, it’s best suited for outdoor use. The two-stroke demolition saw can cut up to a depth of 155mm, so it’s suitable for concrete of similar thickness.
  2. Two Stroke Ring Saw: If your cutting requirements exceed 155mm, you’ll need a ring saw in addition to the demo saw. The ring saw’s design allows it to cut up to 270mm in depth. However, it lacks blade stability when starting a new cut, making it ideal for continuing existing cuts. Like the demo saw, the two-stroke ring saw emits smoke and should be used outdoors.
  3. High Frequency Demolition Saw: This is the electric version of the saw, which runs on power from a regular 240v wall outlet through a power convertor. The high frequency demolition saw can perform tasks similar to the two-stroke version, but without the exhaust fumes. Although it’s slightly quieter, it still produces considerable noise since it cuts through tough concrete. It has a maximum cutting depth of 155mm.
  4. High Frequency Ring Saw: Similar to the two-stroke ring saw, the high frequency ring saw is designed to extend the cutting depth within an existing cut. It can cut up to 270mm.

Step-by-Step Instructions on How to Handle the Saws Safely and Efficiently 

Before starting the sawing process, make sure to follow these steps to handle the saws safely and efficiently:

  1. Wear all necessary safety gear, including goggles, earplugs, dust mask, gloves, and hard hat.
  2. Mark the cutting lines using a concrete marker.
  3. Check the blade alignment and depth adjustment on the saw.
  4. Start the saw and let it reach full speed before making any cuts.
  5. Make slow and steady cuts, applying constant pressure.
  6. Use a dust control system to minimize concrete dust and debris.
  7. Take breaks to prevent injuries and fatigue.
  8. Turn off the saw and unplug it when not in use.

Blade Selection and Cutting Techniques

Blade selection and cutting techniques play a vital role in the success of your hand sawing project. Here are some tips to consider:

  • Choose a blade with the right diameter, thickness, and diamond concentration.
  • Use a wet blade for harder and thicker concrete, and a dry blade for softer and thinner concrete.
  • Use a diamond blade with a high concentration of diamonds for faster and smoother cuts.
  • Make shallow and straight cuts first before going deeper or changing angles.
  • Use a guide rail or straight edge to keep your cuts straight.
  • Avoid twisting or forcing the saw through the concrete material.
  • Use water or a lubricant to cool down the blade and prevent overheating.

Best Practices for Minimizing Concrete Dust

Concrete dust can be harmful to your health and cause respiratory problems. Here are some best practices for minimizing concrete dust:

  • Use a vacuum or exhaust system to trap the concrete dust and debris.
  • Wear a dust mask to prevent inhaling the dust particles.
  • Wet the concrete surface before cutting to reduce dust.
  • Position the saw close to the ground to capture the dust at the source.
  • Clean up the dust and debris regularly to prevent accumulation.

Tips on How to Maintain the Saws for Long-Term Use 

Maintaining your hand saws is crucial for their long-term performance and efficiency. Here are some tips on how to maintain your saws:

  • Clean the saw and blade after each use to prevent rust and corrosion.
  • Lubricate the blade regularly to prevent wear and tear.
  • Replace the blade when it’s worn out or damaged.
  • Store the saw in a dry and cool place to avoid moisture and humidity.
  • Check the saw’s alignment, depth adjustment, and electrical components regularly.

Safety Guidelines for Concrete Hand Sawing 

Here are some safety guidelines you must follow while sawing concrete:

  • Wear all necessary safety gear, including goggles, earplugs, dust mask, gloves, and hard hat.
  • Don’t operate the saw near flammable materials or substances.
  • Avoid using the saw in wet or slippery conditions.
  • Make sure the saw is turned off and unplugged before cleaning or maintenance.
  • Keep the saw away from children or untrained individuals.
  • Follow all local and federal regulations and guidelines for concrete hand sawing.

Material Disposal and Cleanup 

Dumping concrete at a regular dump? Ouch! It can cost a fortune! But don’t worry, there’s a better way – concrete recycling facilities in the city. Yes, they exist, and they can save you a ton of money. The catch? Well, some of them require an account to accept your precious concrete. Here’s the trick – Rent a skip, but make sure to let the hiring company know exactly how much concrete you’re disposing of. That way, they can send the perfect truck for the job, saving you from those pesky reallocating fees.

Thankfully, cleaning concrete slurry up is a piece of cake when it’s wet. But beware! Once it dries, it turns into a rock-solid force to be reckoned with. It’s concrete, after all! So grab that hose and let the water flow, collect any slurry you need, and pack up that trusty saw of yours. 

Oh, and here’s a pro tip to save some extra bucks: give your saw a quick wipe down before returning it. Trust us, avoiding those sneaky cleaning fees is worth the extra effort.


Concrete hand sawing is a versatile technique that requires careful consideration when selecting the appropriate hand saw. With the variety of options available, from standard hand saws to wire saws, it’s essential to choose the right saw for the job at hand. Always keep in mind the noise level, exhaust fumes, cutting depth, and required space for each type of saw.

Remember to follow all safety guidelines, such as wearing protective gear and utilizing proper techniques to prevent injury. And never forget to keep the saw away from children or untrained individuals. More importantly, ensure to adhere to all local and federal regulations and guidelines for concrete hand sawing to ensure a safe and successful project.
