Pressure bursting can be used in cases where relatively quiet, dust-free, controlled demolition is preferred.
Both mechanical and chemical pressure bursting split the concrete, either with a splitting machine operating on hydraulic pressure provided by a motor in the case of mechanical bursting or through the insertion of an expansive slurry into a pre-determined pattern of boreholes in the case of chemical bursting.
The split concrete is then easily removed, either by hand or by crane.
Hydraulic and chemical pressure bursting break up concrete structures with a minimum of noise and flying debris. Both methods work by applying lateral forces against the inside of holes drilled into the concrete, and can do virtually any job other demolition methods are capable of. However, rather than shattering the concrete into bits as dynamite and impact tools would, the lateral forces build up over time to crack the concrete into smaller sections.
Often used in concrete demolition projects in Miami Fort Lauderdale Florida involving bridge decks, foundations, and pavement, hand-held or boom mounted pneumatic and hydraulic breakers are currently the tool of choice.
The amount of work accomplished using these methods depends on the hammer size, the strength of the concrete, the amount of steel reinforcing used in the concrete, and working conditions.
Machine-mounted breakers are able to deliver a range of 100 to 20,000 foot-pounds at 300 to 800 blows per minute. Machine-mounted breakers may utilize:
By cutting concrete elements, and then removing them by crane, the demolition of an entire concrete structure may be carried out with a minimum of noise, dust, and impact on surrounding structures.
This may be done by sawing, water-jetting or thermic lance, and is a particularly good method of demolishing portions of a structure, especially portions of walls or slabs.
One of the oldest and most commonly used methods for building demolition in Miami Fort Lauderdale Florida, the ball and crane use a wrecking ball weighing up to 13,500 pounds to demolish concrete and masonry structures. During the process, the ball is either dropped onto or swung into the structure that is to be demolished.
The ball and crane, however, is not suitable for all demolition applications. Some limitations:
While the concrete can be broken into rather small pieces, additional work in the form of cutting rebar may be necessary.
Only highly skilled and experienced crane operators should be used on ball and crane demolition projects — smoothness in controlling the swing of the ball is important since missing the target may tip or overload the crane and a mild swing-back may cause the ball to hit the boom.
The size of the building that can be demolished with this method is limited by crane size and working room, including proximity to power lines.
This form of demolition creates a great deal of dust, vibration and noise.
Explosives are generally in Miami Fort Lauderdale Florida used for removing large volumes of concrete via insertion of explosive devices in a series of boreholes:
Demolishing concrete structures such as reinforced bridge piers, equipment pads, and pre-splitting lock walls and demolishing or quarrying boulders into any size and shape does not have to be a messy, dangerous or unpredictable task. If your demolition options are limited due to work site issues such as accessibility, vibration, noise, dust and controlling flying debris, then it is time to look into expansive concrete demolition techniques.
Bustar expansive grout is a proven controlled demolition alternative that delivers safe and predictable results you can count on. When applying expansive grout to concrete or rock demolition projects, large objects can be easily reduced to more manageable pieces or complete rubble for excavation and removal. Under ideal conditions, expansive grout can begin to deliver results in as little as twelve hours. This demolition technique can deliver up to 7,000 tons of expansive stress, yet work in a predictable, methodical manner. This means you won’t have to deal with noise, excessive dust, flying rock and debris, vibration from heavy machinery, environmental pollution produced by jack hammering or explosive demolition methods. Used correctly, expansive grout will ease constraints on time, labor and insurance exposure. The predictable nature of rock demolition with this expansive concrete demolition agent also means that the added hassles and expense of security and licensing are not required – handling and use of Bustar expansive grout are always a simple proposition and completely safe.
For complete concrete and rock demolition, concrete demolition agents in Miami Fort Lauderdale Florida can also be combined with controlled demolition services such as Brokke robotic hammering. The companies in Miami Fort Lauderdale Florida operate a fleet of highly efficient and mobile robotic hammers that are standing by for immediate nationwide deployment. With a highly skilled technician at the controls, Brokke robotic hammers are able to efficiently segment or completely demolish concrete structures or boulders into any size and shape. Combined with expansive grout, robotic hammering is able to deliver complete demolition results on work sites where traditional explosive demolition solutions may not be viable or safe. Combined or used separately, robotic hammering and expansive concrete demolition can address work site issues such as safety, efficiency, and accessibility. To achieve rock demolition results, turn to them for professional robotic hammering services and Demolition Technologies for expansive concrete demolition services.
Concrete contractors in Miami Fort Lauderdale Florida dream about placing perfect concrete for precisely positioned columns, beams, and slabs. But sometimes things aren’t quite perfect or plans change and it’s necessary to demolish concrete. In many cases, a 60-pound breaker or a smaller chipping hammer is the answer, but there are alternatives that should be considered, especially when noise, dust, or vibration are important issues.
