Finished concrete looks pristine and makes spaces look classy and elegant. The question arises: what about unfinished concrete? Or perhaps, if your house needs retrofitting. In that case, the homeowner will plan how to revamp indoors, demolish imperfect concrete, tools required to demolish concrete, consult an expert, and most importantly, time and budget. These days, DIYers, rather ingenious workers, look for ways to renovate their rooms, houses, and if working from home, then offices. In such scenarios, concrete demolition tools are a necessity. Here is a guide demonstrating where to use which type of tool and on which type of concrete:
While encountering concrete, picking up the right tool can make the difference between strategic and overburdened work. Having a clear notion of what and why to buy while handling concrete not only eases the working process but also saves time and money; ergo, planning the resources wisely to advance in the plan. Thereupon, is the list of a few tools that will ease the selection for breaking concrete.
Sledgehammer can break boulders, then why not concrete
Sledgehammers, combined with a little grease, are more reliable than a power tool for breaking concrete. These are ideal for thin concrete slabs, having a thickness of less than four inches. They vary according to the handle length and head weight. The head of a sledgehammer can vary from 2 kgs to 7 kgs, and the handle from 3 feet to 5 feet.
Sledgehammers are manageable; consequently, one can start hammering the concrete to break it right away. Raise the hammer slightly above the head level, allow it to fall on the target, and let the hammer work. Moreover, if the concrete is chalked up by a concrete saw, this heavy-headed, classic, and manual tool can shatter the concrete easily into several pieces. Sledgehammers are an absolute fit if the demolition project is small or if someone is working as a DIYer because heavy-duty and high-budgeted tools may not be necessary for those projects.
Chip off the concrete with the Chipping Hammers
Breaking concrete at unreachable places can be challenging, like reaching between the corners of homes, spaces between windows, or other fragile locations. Chipping hammers are ideal for such works. They can reach tight and minute areas, chip off, and give a clear finish to the concrete by providing better control when precision matters. The length of a chipping hammer varies from 30 cm to 50 cm and comes in the range of 2100 to 1300 blows per minute.
The key to mastering the use of a chipping hammer is tip orientation. Knowing how a tool works is as crucial as choosing the right tool. The chipping hammer will create a hole if the straight downward pointing tip strikes the same place repeatedly and may create unwanted cracks in the concrete. Moreover, chipping hammers can be a boon to craft the old-fashioned room into a first-class territory.
How cool can it be cutting concrete with a Cut-off Saw
A cut-off saw is a manually manageable and semi-portable concrete and masonry-cutting tool. Equipped with a razor-sharp and abrasive blade, a cut-off saw behaves like a miniature version of a walk-behind saw. It is a tremendously powerful machine, which possesses a rotating disc fixed on a swing arm. It can cut concrete having a depth up to 15 cm; ergo, making a perfect fit for cutting slabs having rebar.
Cut-off saw can be used manually but requires firm and strong hands as its weight varies from 12 kg to 25 kgs. They can be powered electrically, hydraulically, pneumatically or even with gas. Cut-off saws are suitable for working in closed areas, vertical concrete surfaces and places where concrete needs to be scored. As a consequence, cut-off saws are used mostly in those places where the complete demolition of a house or building is to be done.
Rotary Hammer for taking down those concrete masonry units
A rotary hammer works effectively with a chipping function for the successful removal of concrete. Many misinterpret this as a hammer drill, but it looks more like a handheld jackhammer. It is primarily used for drilling concrete and comes in varying sizes, out of which the exceptionally capable one is the inline D-handle tool.
The adjustable bits of a rotary hammer come in varying sizes, from 1 ½ inch to ¾ inch, which is capable of removing smaller amounts of concrete and a tile from a subfloor. They are great at taking down concrete masonry units, block by block.
A rotary hammer has three settings: just hammer, hammer drill, and drill mode, which can be interchanged according to the type of work. Because of their pounding action that delivers a high impact force, rotary hammers effectively break aged concrete containing rebar or similar stone or rock.
Let the Demolition Hammer demolish everything for you
Demolition hammer is yet another powerful, heavy and pounding tool that can break concrete, with or without reinforcements. It is professionally engineered to demolish every structure within no time. A demolition hammer comes in varying chuck sizes, ranging from 25 mm to 40 mm, and varying weights, ranging from 5 kgs to 8 kgs.
The key to mastering a demolition hammer is to use it at a 90-degree angle between the hammer and the struck surface. This way, one can create the maximum force to break the concrete. As a result, a demolition hammer is suited to break concrete foundations and tear concrete roadways. However, if the demolition hammer is not used properly, it can cause more damage than good.
Do not forget to change the Bits while working with hammers
It is necessary to change the bits from time to time while breaking concrete. For such purposes, shank bits, max bits, and hex collar bits are best suited. Because of a smooth shaft, shank bits work exceptionally well while dealing with thin concrete. However, max bits will come to the rescue for heavy-duty concrete demolition.
Most rotary hammers use max bits to handle more torque while breaking thick concrete. Hex collar bits are suitable for every type of concrete. Therefore, one can rely on hex bits for breaking any concrete.
Are we done yet?
Deciding the right tool completes the task up to 80%. The remaining 10-10% is how we use it and the safety measures we take. For example, choosing a demolition hammer instead of a sledgehammer can fall the house into pieces. Or using a sledgehammer instead of a chipping hammer can break the windowpane or crack the door. Therefore, understanding the mode of operation is the priority if one is trying to accomplish the demolition project. Once it is done rightly, choose the tool and complete the project.
