Demolish Concrete

Home

Hydraulic bursting, crushing, and splitting provide an almost silent demolition technique for removing concrete and masonry into manageable lumps with minimal noise and vibration. These methods offer an excellent solution when working within noise and vibration sensitive environments such as office blocks, hospitals, shopping centres and residential buildings where these constraints exist.

Hydraulic bursting, crushing and splitting breaks up concrete structures by applying lateral forces against the concrete, and represent methods which are able to be used in most situations. However, rather than shattering the concrete into bits as impact tools would, the lateral forces build up over time to crack the concrete into smaller sections.

Hydraulic Bursting

A hydraulic burster consists of a hydraulic powered motor and a burster head / ram, which is made of pistons. Prior to bursting, a series of holes needs to be core drilled into the area needing to be removed. Hole sizes usually ranges between 150mm and 200mm in diameter. The burster head is then placed into the holes one after the other, placed under pressure forcing the burster head pistons to expand within the hole, which in turn causes the concrete to break into manageable pieces. This is repeated until all the area targeted for removal has been separated.

Hydraulic Crushing

The Jaw or Clamp of the crushing unit is placed over the material to be crushed. Once positioned, the operator will activate the hydraulic ram to crush the concrete or masonry within the clamp. This crushing technique creates a non-percussive sheering action, causing the integrity of concrete to break down under the pressure. This process is repeated in bite sized increments and concrete is removed as the work proceeds. The Crusher consists of a large jaw (which looks like a large letter ‘C’ or ‘D’ or a crabs claw) and a hydraulic power unit.

Hydraulic Splitting

Used in conjunction with drilling..... powerful hydraulic wedges are inserted into pre-drilled holes and mechanically expanded until the material is forced apart. Once the integrity has been broken down, the concrete can be removed using your preferred method. Darda Splitting sequence: a hole of a precise diameter and depth is drilled into the material. The wedge set (one wedge and two counter wedges) is inserted into the drilled hole; the wedge is driven forward under hydraulic pressure, forcing the counter wedges apart with a force of up to 400 tons. The material splits within seconds. With enlarging counter wedges the split can be expanded.

Applications

  • Removing large masses, plinths, suspended floor slabs, reinforced concrete walls or other redundant reinforced concrete structures
  • In working environments such as office blocks, shopping centres, residential buildings and hospitals - anywhere that requires large lumps of material removed quietly and free of vibration
  • For use in close quarters and hard to access places where space is restricted or confined

Benefits

  • Virtually silent in process
  • Inexpensive and dust free
  • No vibration or flying debris
  • Powerfully effective against deep concrete masses
  • Works as an alternative method to noisy percussive demolition
  • 80 tonnes of pressure delivers an exceptionally powerful solution
  • Precise and controlled
