Concrete Sawing — Types and Techniques
As a construction industry worker, you should be familiar with concrete sawing. The process is essential for cutting and removing concrete in building and remodeling projects in a safe and accurate manner.
However, there are many distinct varieties of concrete saws, each of which is appropriate for a different task.
Additionally, there are numerous distinct concrete sawing methods.
Here is a quick guide to concrete saws and sawing that will assist you in deciding which saws and sawing methods would best suit your needs.
There are two main methods used for concrete sawing.
Water is utilized in this concrete sawing technique to lubricate and cool the saw blade, resulting in a cooler blade and less detrimental dust production.
It is better for your health and the environment, and it also helps the blade last longer.
This technique is only appropriate for outside projects because it frequently generates a lot of dust on the job site.
A diamond blade is the best choice for dry sawing since it maintains its cooling even in the absence of water and can help prevent the accumulation of dust.
To prevent the blade from overheating, dry sawing requires making numerous shallow, quick cuts that gradually get deeper.
DIFFERENT SAW TYPES
In essence, wire saws are diamond-coated cables that are cooled with water and dragged through the target material.
There is less likelihood of fractures developing around cuts thanks to the flexibility, reduced waste and generally low vibrations of this method of sawing concrete.
A wire saw can handle any size project or building. It is made to make precise cuts in reinforced concrete or steel.
Chain and Ring Saws
Chain saws are perfect for tasks where overcuts are not required since they have an oblong blade that is surrounded by a diamond-impregnated chain.
In contrast, ring saws feature a round blade and are the best choice for deep cuts in areas where other saws cannot reach.
The main advantage of these saws is their small size, which makes them perfect for cutting through walls, floors and concrete pipes.
Wall saws, sometimes known as "track saws," are typically used to cut openings in walls so that doors, windows or ducts for ventilation can be added.
The wall saw is installed on a track and fastened to the target building to create accurate, precise cuts.
CONCRETE SAWING TECHNIQUES
The technique is an essential component of good concrete sawing. It can have a significant impact on the project's outcome, even with the right tools and the perfect amount of planning. Here are important points to remember:
Position: The blade should be parallel to the surface being cut, and it should be held with both hands.
Speed: To ensure clean cuts, it needs a slow and steady application.
Cooling: To keep the blade from overheating and prolong its life, it should be periodically cooled.
Cleaning: To improve precision and guard against blade damage, it's crucial to thoroughly clean the saw and the area around it after each cut.
