A brief guide on how to fix leaks in concrete walls, including the cause of leaking in concrete and how to detect leaks
Knowing the hardiness of concrete, it’s hard to imagine something as delicate as water being able to seep through and cause severe damage to a structure. And although concrete itself puts up a good fight against water, there are still plenty of ways leaks can arise in concrete walls and other foundational parts of structures and buildings. Here is a brief guide on how to fix leaks in concrete walls – we hope you find it useful!
What causes leaking in concrete?
It’s important to know the cause of a leak before it can be properly prepared. During a feasibility survey, our team will assess the leak before prescribing a suitable solution.
Here are the most common causes of leaking in concrete, those which inevitably lead to the need for repair:
- Hidden/broken pipes
- Broken concrete slabs in roofs or flooring
- A corrosive environment or failure of waterproofing
- Cracks in concrete
- Improper concrete placement or poor workmanship
- Improperly prepared concrete or poor workmanship
- Low-graded or contaminated aggregate/aggregate that has not been sieved prior to application (used to make concrete)
- Structures encasing a water supply, like a water tank
How to detect water leaks in concrete walls
Before we detail the options of how to fix leaks in concrete walls, it is important to explain how to detect a leak first. If you are reading this blog because you want to fix a new leak, and you’re one step ahead, skip to the next section.
There are signs and symptoms when looking for water leaks in concrete walls. These include, but are not limited to:
- Discoloured patches of wall
- Hot-to-touch patches
- Puddles of water/wet surroundings where the leak has cascaded down the wall
- Bubbling, which is more apparent if the concrete wall has been treated by a coating or paint
- In severe leaks, the wall might curve or warp
- The presence of mold, mildew, or both
- You may be able to hear dripping water
- You may be able to smell must or damp.
