Why is it important to reinforce concrete structures underwater? High water pressure, salt that corrodes, and sea plants that stick to the concrete can make the structure crack and become brittle. For this reason, it’s important to know the tricks of reinforcing concrete so that your project doesn’t just last a year or two, but can last for decades.
So, how do you make an underwater concrete structure sturdy despite the waves, corrosion, and sea creatures? Here, we’ll explore simple but effective ways to make underwater concrete strong and durable. Check it out!
Techniques for Reinforcing Underwater Concrete Structures
The success of a project depends on the methods used to reinforce the concrete. So, how do you keep the concrete down there strong? Here are some techniques you can use.
1. Use High-Performance Concrete Grouting
High-performance grouting is designed to withstand extreme pressure and chemical attack from seawater. It has exceptional durability due to special additives that make it stronger and anti-corrosion. Plus, its waterproof and washout properties make the structure safer during application. Suitable for harbor projects or bridge foundations.
The shape of this grouting is also flexible, you can make unique shapes or large structures as needed. So, no need to worry about aesthetics or function. One of Estop’s grouting products that is suitable for this condition is Estogrout UW and Estogrout UW Premix.
2. Anti-Corrosion Coating
Anti-corrosion coating will protect the concrete from seawater. You know, right, that seawater is full of salts that can make concrete surfaces porous. Well, you can reinforce concrete structures underwater by using this anti-corrosion coating. One of Estop’s anti-corrosion coating products is Estotect Zincrich.
3. Upgrading with Fiber Reinforced Polymer (FRP)
Ever heard of concrete with added fibers? That’s called FRP! It makes concrete stronger and more resilient. For underwater projects that are often exposed to currents or vibrations, FRP is a lifesaver as it absorbs the energy from shocks. This means that small cracks can be prevented before they become big problems. Plus, the process of using it is also easy and hassle-free. One of Estop’s FRP products that is suitable for these conditions is Estowrap 300 + Estowrap Resin UW.
4. Epoxy Injection Technique
If it has started to crack, epoxy injection can be a solution for reinforcing concrete structures under the sea. It is like a glue that makes the cracked concrete return to its original shape and become strong again. The process is quick, simple, and there is no need to dismantle the concrete structure. Very practical for small repairs but with maximum results. Some of Estop’s epoxy injection products are Estorex EP10 and Estobond EC.
5. Cathodic Method (Cathodic Protection)
This is the best method to stop corrosion before it gets worse. This cathodic protection system uses electrochemical reactions to make the subsea concrete resistant to corrosion attacks. Although the initial cost is quite high, the long-term effects are rewarding. Save on structural maintenance. So, more peace of mind and cost-effectiveness in the future.
So, those are some of the ways to reinforce concrete structures underwater that can make your project more durable and drama-free! The point is, if you don’t want to be bothered by damage in the future, make sure to use the right technique from the start. All of the above techniques have their own advantages. So, customize them according to your project needs.
