Seovic, operate two specialised slip-forming machines, servicing a niche engineering market for the construction of concrete walls and traffic barriers.


The single focus construction operation offers the market a highly technical process to produce formed road barriers and walls in one continuous stream using a specially designed concrete mix.


This process is much faster and more efficient than the traditional cast in-situ or pre-casting off-site processes.
