We provide comprehensive rebar corrosion surveys including non-intrusive identification and analysis of your concrete structures and their potential rebar corrosion.
WHAT IS REBAR CORROSION?
Rebar, short for reinforcing bars, are steel bars which are commonly used as tension devices to reinforce structures and materials such as concrete. This is done as a means to both strengthen and aid the material under tension. Although concrete is a naturally strong material under compression, it does nonetheless have weak tensile strength. Placing rebar at the core of a concrete structure therefore allows its tensile strength to be significantly increased.
However, over time and as chloride ions come into contact with materials such as concrete and rebar, substantial corrosion is likely to occur. When steel rebar corrode, the resulting rust ends up occupying a larger volume within the structure than the original steel. This means that the rebar will lose its strength and ability to make the concrete more tensile.
HOW TO REPAIR REBAR CORROSION?
When rebar corrosion occurs, their structures will need to be repaired or replaced. Here, at structural Repairs, we are proud owners of some of the latest Corrosion Detection Technology such as wireless and non-invasive measurement devices. This technology allows us to evaluate the health of your reinforced concrete structures and detect corrosion potential, corrosion rate and in-situ electrical resistivity. A real-time contour mapping of the condition of your concrete and its rebar is them presented and handed to you.
More About our Rebar Corrosion Services
Repair & Treatment
Repairing rebar corrosion is undergone by removing the degraded concrete to the depth of 20 to 30mm behind the faulty rebar. All corroded material is then removed and the rebar is either treated or replaced.
The award-winning technology we use is non-invasive and non-instructive and utilised in order to analyse the current condition of your concrete.
Via the technology used, measurements are obtained and evaluated within seconds and exported in the form of a report for you to keep. Multiple and directional parameters are able to be tested in a single measurement.
Rebar Corrosion FAQs
We’re here to help! Here you’ll find the answers to the questions we get asked the most about rebar corrosion. If you would like to know more, get in touch for a free consultation.
- How to prevent rebar corrosion?
There are several ways to ensure your rebar does not end up corroding while supporting your concrete structure. Some of these include employing watertight concrete and proper cover, applying non-chloride accelerators, applying cathodic protection, applying appropriate sealers, implementing specialty concrete overlays, using certain rebar types such as epoxy coated or stainless steel rebar, and much more.
- What is rebar corrosion?
Rebar corrosion is when the steel reinforcing bars found within a concrete’s structure have began to corrode and accumulate rust over time.
- How much does a rebar corrosion survey cost?
Rebar corrosion identification surveys are conducted through various different methods and come with many different and unique price tags. Overall, rebar identification surveys are likely to start from £600, however, please feel free to get in contact with us in order to attain a free cost consultation regarding details tailored to your specific situation.
- Is corroded rebar OK to use?
When you have steel rebar that has been exposed to salt water and has visible rust it is important to treat it by using high-pressure washing or to replaced the rebar altogether. Salt water can cause a more serious corrosion issue than other causes of which may make the rebar structurally unsuitable.
- What causes rebar corrosion?
Rebar corrosion occurs when reinforced concrete is exposed to chloride ions. The intrusion of chloride ions, present in deicing salts and seawater, into reinforced concrete can cause steel corrosion if oxygen and moisture are also available to sustain the reaction.
