CUTTING & CORES
The slab saw, the most commonly used method for removal and alteration of concrete, is a large 2,000 lb walk-behind, motorized piece of equipment used primarily to cut horizontal flat surfaces such as floors, bridge decks, and pavements. Also referred to as a flat saw, it is a cost effective and time saving means to provide sawing for expansion joints, removal of damaged parking lot sections or isolation of slabs to remove for demolition purposes.
Gas and Diesel Slab Sawing are the most common options used for applications outside, where there are no confined spaces that would trap any fumes created as a by-product of the gas motor. Using our wet cut diamond blades, the slab saw is capable of cutting, dust-free, up to 33" deep.
Electric Slab Sawing is a common method used for interior cutting when gas and diesel engines are not permitted, there is a lack of ventilation, or contamination to product or personnel is a primary concern. Typical application for interior electric slab sawing is within businesses that produce or store food and drugs, small spaces within highrise buildings or underground utility installation.
Our electric saws are powered by 3 Phase/480 Volt generators equipped on our trucks and are capable of cutting up to 24" deep.
Wall sawing is the most versatile method used for the removal and alteration of concrete. The wall saw is a track mounted machine that uses diamond blades for cutting new door, window, mechanical, or other wall penetrations. The wall saw is also commonly used on any vertical wall, or bridge space, where the area is too small for large equipment access.
The power source for wall sawing is typically hydraulic or high-cycle electric, which is preferred to avoid the chance of any line spills which could become hazardous. The wall saw can mount to any surface whether it be a vertical wall, floor, steep incline or overhead, making alteration and removal of tricky concreted areas a little less troublesome. With the use of wet-cut diamond blades, wall saws are capable of cutting dust-free up to 32" deep.
Hand sawing is a method for cutting concrete which utilizes hand-held devices and is most ideal for cutting in small, confined areas or anywhere that the use of conventional equipment and methods is restricted. Hand sawing typically refers to the lighter duty use of diamond blades; therefore, allowing for portability, speed and accessibility at restrictive or smaller construction and demolition sites.
Hydraulic and electric hand sawing is generally used for sawing concrete pipe to length; creating openings for electrical, HVAC and plumbing purposes; correcting overcuts associated with other types of sawing; and/or precision trimming.
Our operators are equipped with hand-held devices capable of cutting material from 4" to 12" deep.
& Chain Sawing
Core drilling, most commonly used when a circular hole is needed for passage through a concrete structure or surface, is most typically used for drilling holes for plumbing and pipe work and for electrical and/or HVAC installation purposes. Other reasons for choosing the core drilling method would be feeding telecommunication lines or for anchor bolts. Holes can be drilled at multiple orientations, including vertical, horizontal and inverted or angled penetrations. The core drill is also portable and can be hand-held or mounted for drilling purposes. B&D provides drill sizes in 1/2" increments up to 60" in diameter.
Chain sawing, while perfect in theory, reigns as "champion" of the most expensive means for cutting concrete. Chain sawing is most effectively used for eliminating overcuts and cutting smaller dimensioned wall and slab cuts.
B&D provides this service only when all other possible alternatives for saving money and effectively cutting the area for removal or isolation have been ruled out.
Our equipment inventory hold over 20+ different sized chainsaws. Please consult a B&D sales professional for less expensive options available to you before solidifying a decision for using this method.
