CORROSION PREVENTION AND REPAIR FOR CIVIL ENGINEERING

Reinforced concrete structures are generally very durable. However, if contamination from chlorides occurs or the concrete becomes carbonated then corrosion of reinforcing steel may take place.

Bridges or other highway structures and multi-storey car parks can suffer from chloride contamination from de-icing salts. Marine structures such as jetties and wharves, marine bridges and tunnels can all suffer from chloride ingress due to their location.

Corrosion Prevention Limited can assess structures for corrosion risk, undertake investigative and quantitative surveys, design and specify repair and protection systems including concrete repairs systems, galvanic or impressed current cathodic protection systems and other methods of corrosion prevention.


CORROSION PREVENTION AND REPAIR FOR BUILDINGS

Reinforcement in concrete frames and concrete cladding panels can deteriorate due to carbonation of the surrounding concrete or contamination due to windblown chlorides or cast-in chloride set accelerators.

Masonry clad steel frames, in particular those from the late 19th and early 20th centuries are susceptible to corrosion, as a result of porous cladding materials, mortars and detailing that enables water saturation of the frame.

Corrosion Prevention Limited can assess structures for corrosion risk, undertake investigative and quantitative surveys, feasibility studies and trial installations, design and specify cathodic protection systems and corrosion monitoring systems.


CORROSION PREVENTION AND REPAIR FOR PORTS, HARBOURS & TERMINALS

Accelerated Low Water Corrosion (ALWC) is a widespread phenomenon that can result in rapid section loss of both sheet steel and tubular steel sections at the lower tidal levels.

Steel structures will also suffer from corrosion in their buried, immersed and atmospherically exposed sections in the marine environment.

Corrosion Prevention Limited is expert in designing cathodic protection systems to prevent against ALWC, for both existing and new structures. Such systems may be either galvanic anodes or impressed current. We can also offer general advice on corrosion prevention measures for all port infrastructure.


CORROSION PREVENTION AND REPAIR FOR OIL & GAS

Buried metallic structures, such as pipelines, tank bottoms and well casings are all susceptible to corrosion. Often the importance of this infrastructure and the corrosive nature of the environment can mean corrosion prevention measures are critical. The combination of coating and cathodic protection systems can provide the required service life for buried structures.

Corrosion Prevention Limited can assess the corrosivity of ground conditions, design and specify cathodic protection systems, including galvanic and impressed current systems.

We can offer system audit and advice on specialised surveys for pipeline cathodic protection systems.
