Hydraulic bursting

Minimising sound pollution reduces local disruption.

Hydraulic bursting is a controlled demolition technique comprised of diamond drilling a series of holes in predetermined positions. A hydraulic burster is then used to force the concrete to crack, enabling removal.

The burster heads are inserted into the pre-drilled hole and as the lateral pressure from the motor through to the burster heads builds against the sides, cracks are induced to the concrete. Each drilled hole weakens the structural integrity and causes the next hole to collapse more easily as the process continues. The depth can be increased by adding more burster heads.

The maximum bursting power possible amounts to 2,000 tonnes PSI. This technique is particularly suited to the demolition of foundations, pillars and concrete walls over 300mm thick.

The hydraulic bursting demolition technique is very quiet and non-vibrational and can be carried out within occupied areas.
