Anyone working on a structure made from concrete, reinforced concrete or any form of masonry is familiar with the need to make various types of modifications in these hardened materials. In many cases, these modifications take place on flat, horizontal surfaces such as interior floors or parking lots. At one time, the only way to penetrate a hardened, flat surface was to bring in a jackhammer. However, jackhammer use comes with a number of regrettable drawbacks, including poor control over the accuracy of the cutting process and the creation of difficult-to-handle rubble piles.
For these and other reasons, construction managers have largely abandoned jackhammer use and now rely on specialized flat saws, which come equipped with tough, diamond-tipped circular blades. These modern pieces of equipment offer a number of important advantages, including:
Precise, predictable cut lines
Easy cutting through a wide range of material thicknesses
Increased project speed and efficiency
Simpler removal and cleanup procedures
Some flat saws are relatively small and hand-operated. However, professionals also frequently rely on larger walk-behind models mounted on wheeled carts. This portable equipment layout makes it easy for a trained operator to make accurate cuts. It also makes it possible to maintain the safety standards needed to minimize the risks for jobsite injuries.
img03Asphalt Cutting is implemented to make highly accurate cuts in asphalt surfaces. A highly experienced contractor will use a flat saw to expertly cut asphalt for the purposes of demolition, development, and other projects. From asphalt roads to driveways, asphalt over concrete and parking lot cutting.
In the hands of a skilled operator, these saws have an extremely wide range of potential uses in structures made from concrete, reinforced concrete and/or masonry. Common examples of these many uses include:
- Creating expansion joints (also known as control joints or movement joints)
- Creating the trenches needed to install building utilities
- Accessing building utilities for needed repairs or replacements
- Removing damaged segments of material
- Repairing serious cracks
- Making the openings required for certain kinds of ductwork, and Making the openings required to install staircases and elevators
- Cutting openings for windows
- Cutting openings for doors
- Enlarging previously cut windows and doors
- Making all kinds of flush cuts in vertical or angled material
- Creating vent openings
- Creating overhead doors
- Modifying existing walls
Creating the openings required for vault installations Making the cuts needed to install stairs, and Performing the complex cuts needed to make chamfered edges Sawing also frequently plays an important role in the demolition of horizontal structures. In addition to performing well on floors and similar indoor surfaces, this type of saw is also an excellent option for work performed on the outdoor surfaces of structures such as bridge decks and roofs.
A properly equipped saw can also cut through surfaces made from asphalt. This type of work requires a switch to a specialized saw blade designed to handle the typical mixture of pitch (i.e., tar) and aggregate materials found in these surfaces. Common reasons for asphalt cutting include:
Removal of damaged segments of pavement during a larger repair process Preparation for the repair of isolated cracks, and The creation of various kinds of trenches
