Other Masonry Saws
Handheld concrete saws are one of the most versatile machines on the jobsite, they typically come in 12”, 14” and 16” diameters. They can be fitted with different blades to cut almost anything from, concrete, brick, block, and even metal. Gas driven saws have dominated the market but now electric and battery-operated machines have been gaining popularity.
Soff Cut Saws
Are used for creating joints in newly poured concrete slabs to prevent cracking. One of the most costly issues contractors have is to come back to a job to fix cracks in slabs. These saws also allow the end user to cut expansion joints the same day as the pour instead of coming back days later to make the same cuts, which increase job and labor costs and time. Different blades can be purchased for different styles of cuts
Concrete Chain Saws
