The Benefits of Graviti® MassBloc®


Dry stacked, mortar less construction.
The system can tolerate movement and settlement without causing visual distress at the face. Graviti® MassBloc® walls are relatively flexible structures.


Graviti® MassBloc® walls have very high permeability tested to 12,050 litres flow through 1 square meter of Graviti® MassBloc® per Hour.

This high rate of permeability eliminates the development of hydraulic pressure behind the wall structure


Graviti® MassBloc® components are manufactured from wet-cast concrete, resulting in a very durable retaining wall system.

Our Graviti® MassBloc® is resistant to cracking and do not splinter or decay like treated timbers. Our Graviti® MassBloc® contains no steel reinforcement (apart from a galvanised Swift Lift lifting anchor) and have no exposed wires to corrode like the old fashioned Gabion cage system.

Rapid Deployment

Two experienced workers with an excavator can place up to 80m2 of wall per day. Graviti® MassBloc®’s are easily lifted and placed using the galvanised Swift Lift Anchor cast into the top of each MassBloc®. Using this system entire retaining walls can be built in a fraction of the time spent on many other systems.


The Graviti® MassBloc® system is competitively priced when all project costs are taken into account, including installation time, traffic control, durability and in-place performance.


All Graviti® MassBloc® walls must be built in accordance with site specific design, your local council regulations, and prepared by a registered engineer. Gravity Wall Systems can provide a design service as part the Graviti® MassBloc® package, if required.
