The most important question when it comes to concrete demolition techniques is whether the circumstances demand demolition at all. Concrete elements are crafted to withstand tremendous pressures. Removing them can be even more of a challenge than putting them in place.
Concrete demolition methods, coordinated alongside concrete removal and replacement efforts, become necessary when there is:
· Widespread cracking
· Frost heave (i.e., when moisture seeps into the ground and freezes, pushing the concrete upward)
· Planned improvement, like street and road modifications
Widespread Demolition Techniques
Demolition companies work under demanding conditions. Building demolition must often be conducted in the middle of a city block where traffic, pedestrians, and other structures become factors. That is why many demolition contractors have turned to various techniques that allow them to operate without the usual dust, vibration and noise associated with demolition:
Though it seems counterintuitive, using water to cut concrete has proven to be an efficient demolition technique. It can be administered through a variety of devices, including handheld “guns” and robotic demolition equipment.
There are limitations, however. Hydrodemolition isn’t really cost-effective for remote areas where water must be trucked in, usually at great expense. And in cities where water is readily available, there are usually local regulations regarding the disposal of water, particularly water carrying slurry. Before using hydrodemolition, consult a local environmental officer.
2. Pressure Bursting
This demolition technique is accomplished by drilling holes in the concrete. These holes, when drilled deep enough, form cracks that can then be used to remove a portion of concrete. By applying expansive grout to the drilled holes and giving it a few hours, cracks can be created precisely where they’re needed in the concrete.
This involves concrete cutting tools coupled with a crane to help remove the sawed concrete. This way, a demolition can be performed with very little noise, dust, or damage to surrounding structures. For this reason, A-Core favors dismantling methods, usually utilizing concrete saw cutting or robotic hammering.
