The effectiveness of modern concrete floor saws has been singled out for praise.

According to contractor firm AffordableConcreteCutting.com, the old-fashioned dusty "jack hammer" method was quite a messy procedure.

However, modern concrete floor saws - which use diamond-impregnated floor saw blades - were said to be far superior in comparison.

"Modern concrete cutting leaves a smooth attractive finish," it commented.

One good example of a first-class product is the Barikell Floor Saw, which is powered by a 20HP Honda engine.

This is a very versatile tool and can be used on even the most intensive concrete floor layers, in which case a 30HP Honda engine could be used.

Meanwhile, Elizabeth Arnold of eHow has advised anyone using a concrete floor saw to make sure they always hold it with both hands.

This is because a saw operative may need to raise and lower the blade in order to ensure it cuts through the concrete in a controlled manner.
