Different demolition methods and equipment might get used during heavy industrial concrete demolition. Which methods and tools chosen will depend on the job’s scope and what needs to fulfil the project’s goals. The size of the site and the access available will make a difference in the demolition methods used and which equipment is best to employ.
Two main ways of demolishing concrete include pressure bursting and pneumatic and hydraulic breakers.
Pressure Bursting
Pressure bursting is a good choice when quieter, cleaner, and more controlled concrete demolition is required. There are two options for pressure bursting: mechanical pressure bursting and chemical pressure bursting. Both methods split the concrete, the former using a machine and the latter using an expansive slurry inserted into boreholes. After separating, the concrete can be removed by hand or, in the case of larger pieces, by crane. Pressure bursting helps to reduce noise and dust, allowing for a quieter and cleaner worksite when demolishing concrete structures.
Pneumatic & Hydraulic Breakers
Pneumatic and hydraulic breakers often get used to demolish foundations, paving, and similar structures. There are different sizes of these tools available, which enables them to get used on projects of various sizes. They can feature benefits such as telescoping booms, remote control operation, and even underwater operation. Therefore, they can be a good choice for accessing locations that might be harder to reach.
One of the traditional demolition methods is using a ball and crane, which can be effective. Still, it is not always the best option, as it requires a skilled operator who can aim the wrecking ball correctly to hit its target. The size of the crane and specific access issues may also limit the size of the building that can get demolished.
Other tools used in heavy industrial concrete demolition include saws, water jets, and thermic lances. These tools cut and dismantle concrete so it can be removed as quietly, safely, and discreetly as possible. Water jets help minimize dust, reduce fire risk, and cut straight lines and contours. Thermic lancing can work well in the presence of reinforcing steel and eliminate vibrating and dust problems.
