Concrete Rehabilitation
Multidisciplinary construction group Stefanutti Stocks participates in a broad range of concrete structure and infrastructure construction projects. In addition to constructing greenfield projects our Civils Discipline also offers particular expertise in the field of maintenance, structural concrete repair and rehabilitation.
We offer the mining, industrial, petrochemical, power, water, transport, and building sectors economical repair strategies and implement market-leading technologies to ensure that existing and aging infrastructure assets stay in service for their intended lifespan.
Our rehabilitation teams provide clients with a vast range of capabilities, catering for small, medium and large sized projects of various complexities – from epoxy crack injection to jacking and widening of bridge structures; from installing unique access systems to South Africa’s largest cooling towers and chimneys, through to carrying out extensive concrete repairs. We also undertake preventative maintenance and scheduled condition assessments that minimise the requirement for ad-hoc maintenance and keeps existing concrete infrastructure in working condition.
