DeltaBloc® Concrete Barriers
The MASH compliant range of DeltaBloc® DB80 precast concrete barriers are widely recognised as the industry’s preferred temporary safety barrier system. The DeltaBloc® F-shape systems are designed to safely contain and redirect errant vehicles travelling adjacent to workzones and construction sites.
The DeltaBloc® designs feature a unique tension bar and coupling system providing lateral support during a vehicle collision. DeltaBloc® is available as three (3) options providing designers with a specific solution to meet site deflection and vehicle containment requirements.

DeltaBloc® Concrete Barrier FAQs
What is a precast concrete barrier?
A precast concrete barrier is poured in the safety of a batching plant and transported to site as a preassembled element. A precast concrete barrier can be deployed rapidly, minimising disruption to traffic and reducing labour costs.
What element sizes are available with DeltaBloc® Concrete Barriers?
DeltaBloc® is available in standard element lengths of 6m. At workzone sites where the barrier is required to follow a horizontal curve, shorter elements of 4m and 2m are available.
Do I need to connect each concrete barrier element?
Yes. Installations of unconnected concrete barriers cannot be considered a safety barrier system. Individual concrete barrier elements may slide or topple over during a vehicle impact creating significant risk to workers and other road users.
How do I position the workzone solution at my worksite?
Sufficient clearance between the temporary concrete barrier and worksite must be provided to accommodate the expected dynamic deflection or working width of the safety barrier system. The deflection & working width of the workzone solution is dependent upon the speed and mass of the impacting vehicle, the angle of impact and the performance characteristics of the workzone solution.
What is an anti-gawk screen?
An anti-gawk screen is an attachment to a workzone barrier providing site security and privacy. An anti-gawk screen reduces the visibility of construction work occurring behind the workzone barrier which may be distracting to passing motorists.
What anti-gawk screens are available for attachment to DeltaBloc® concrete workzone barriers?
Subject to the approval of the Project Manager, DeltaBloc® concrete barriers may be installed with wire mesh screens or HolyPan blockout screens.
