How to repair a water leaked wall cracks


We all recognise that concrete is prone to cracking, so we do everything we can to prevent it. Of course, not everything turns out the way we want it to. Concrete can crack for a variety of reasons, and protecting against them all can be difficult. According to the ICRI’s publication, the Concrete Repair Bulletin, there are a few causes that enhance the likelihood of concrete cracks. Steel corrosion, cooling and thawing, a sulphate assault, and an alkali-aggregate reaction will all be involved. If you notice that the concrete crack has begun to seep water, then this will looks even worse.

How to fix a concrete fracture.

Whatever leaky concrete crack you want to repair, make sure you prepare for it first. It’s the only safe approach to ensure that the crack is completely waterproof once fixed. Get out your electrical splintering hammer first. Then, chisel through the crack’s whole length to create a deep, thin chase. Following that, you’ll be able to prepare to fill within the chase you just created.

You may be tempted to use an injection product to fill in the gaps in this chase, but please take a step back, don’t do that or you will be regret after this. The procedure you’ve just begun sounds similar to what you did previously with an injection product, but it’s not quite the same. If you were going to use an injection product, for example, rather than chiselling out a chase, you’d normally drill holes along the length of the crack. The product would then be pumped into each of these holes via a port. However, if you simply have a well-defined chase to pour product into, you will not achieve the same result. Not to forget that some injections will not be able to withstand movement in the concrete indefinitely. Urethane foam injections, for example, are generally adaptable and can withstand some movement. This elasticity, however, can degrade over time.

Either way, avoid using an Epoxy Injection.

If you intend to return and investigate the injection route, do not use an epoxy injection. True, this type of injection is intended to reinforce and restore the integrity of the concrete crack. However, it can only accomplish this if the crack is dry, therefore it is not ideal for water-damaged fractures. We recommend instead utilising a hydraulic cement and a hydraulic grout solution

While our approach will undoubtedly prepare you for some of the worst concrete leaks you’ve ever seen, there is always room for improvement. After all, dealing with a leak that develops during new construction is not the same as dealing with an existing leak. Fortunately, Malaysia has many building cracks repair specialists. They will share their knowledge on concrete leak fixes in new construction.
