Hydraulic Bursting

A quiet and efficient method of controlled demolition used to remove large concrete masses such as foundations, columns, floor slabs and walls.

We are able to offer two ranges of bursting equipment, Darda & Hydrostress. The former only requires 48mm holes to accept the burster wedges while the latter requires either 112mm or 180mm diameter holes.

Holes are drilled in the concrete structure and the burster head is inserted, which is then expanded by hydraulic fluid power.

The build-up pressure inside of the holes induces cracks in the concrete. The cracking follows the plane of weakness created by the holes that were drilled previously. The process is repeated until the whole structure is fractured into smaller sections and ready for removal.

The power units for the burster’s can be 110 volt electric, three phase electric or engine driven.
