For a controlled demolition that is relatively quiet and is dust-free, pressure bursting is the solution.
Splitting concrete can be done either by mechanical or chemical pressure bursting using a couple of different methods. These include a hydraulic pressure motor for mechanical bursting or inserting an expanding slurry into pre-drilled boreholes for chemical bursting.
The resulting split concrete can then be removed by contractors who specialize in concrete demolition in Chicago.
Hydraulic and chemical pressure bursting can both bust up concrete while keeping the noise and flying debris to a minimum.
Mechanical Bursting Expectations
- Inexpensive with no noise or vibration
- The boreholes needed will create some noise and vibration
- Diamond-tipped drilling reduces noise and vibration during hole drilling but can be more expensive
- Controlling how the concrete is demolished and its movement is difficult
Chemical Bursting Expectations
- This is a costlier method for pressure bursting
- Offers greater control over how concrete is split
- Over 4300 PSI of chemically induced pressure may be generated within 10 to 20 hours to crack concrete
- Silent with no vibration and very little dust
Pneumatic and Hydraulic Concrete Breakers
Usually used for projects requiring concrete demolition in Chicago, including bridge decks, foundations, and pavement, the preferred choice is a hand-held or boom-mounted pneumatic and hydraulic breaker.
The level of work required when using these methods depends on the hammer size, density of the concrete, how much steel reinforcement was used in the concrete, and the working environment. Expect 100 to 20,000 foot-pounds at 300 to 800 knocks per minute from machine-mounted breakers.
