The Civilmart MassBloc Instant Wall System is comprised of large permeable precast concrete blocks, for various retaining applications, for walls typically 2-8 metres in height. MassBloc can be supplied in a number of colours, resulting in an attractive, vandal resistant, retaining wall system.

MassBloc Instant Wall System

The no-fines mix aids resistance to shearing by increasing friction between units and the permeability helps to relieve hydrostatic pressure build-up behind the wall.

The units are interlocked and construction is mortarless for rapid assembly (up to 75m² per day). With minimal labour & machinery requirements to install, MassBloc becomes a cost effective system over the installed life-cycle.

Availability of varying height units, and a block design that allows for varying radii curves, makes the system easily adaptable to any site.
