- Safety gear (gloves, goggles)
- A shovel
- Waterproof sealant or epoxy
- PVC pipes and connectors (if necessary)

10 Easy Steps on How to Repair Water Leak Under Slab
Step 1: Locate the Leak
The first step in repairing a water leak under the slab is identifying its location. Look for any signs of moisture or mold on your floors or walls, and listen for the sound of running water. Also, check your water meter to see a continuous flow even when all faucets are turned off. These are all indications of a water leak under your slab.
Step 2: Excavate the Area
After locating the leak, start the excavation process. Safety is paramount, so put on your safety gear before starting. Use a shovel to dig around where you suspect the leak is. Dig until you reach the slab, then carefully break the slab using a jackhammer or a suitable tool.
Remember that the aim is to expose the leak without causing further damage to the pipes or the slab.
Step 3: Inspect and Identify the Leaking Pipe
Once you have exposed the leaking area, it’s time to identify the pipe causing the problem. You can do this by visually checking the pipes for any signs of leakage, such as dampness, water dribbles, or corrosion.
If visual inspection doesn’t reveal the leaking pipe, you can use an electronic leak detection device for more accuracy. Remember to shut off the water supply before proceeding to the next step.
Step 4: Repair the Leaking Pipe
After identifying the leaking pipe, you are now ready to repair it. If the leak is due to a small crack or hole in the pipe, you can use a waterproof sealant or epoxy to fix it. Thoroughly clean the area around the leak, then apply the glue or epoxy. Allow it to dry and cure according to the manufacturer’s instructions. If the pipe is severely damaged, it may need to be replaced.
If this is the case, remove the damaged section of the pipe using a pipe cutter and replace it with a new section of PVC pipe, using connectors to secure it in place. Always turn off the main water supply before carrying out this step.
Step 5: Test the Repair
After you’ve successfully repaired or replaced the leaking pipe, it’s time to test your work. Turn the water supply back on and check the repaired pipe for any signs of leakage. You’ve successfully fixed the leak if you can’t see any water seeping out. However, if you notice water still leaking, you might need to reapply the sealant or reposition the new pipe, then test the water flow again. Always ensure to perform this step carefully to prevent any new leaks from occurring.
Step 6: Refill the Excavated Area
Once you’re sure that the leak has been properly fixed, it’s time to fill in the excavated area. Carefully place the soil back into the hole, ensuring that it does not cause any damage to the repaired pipe.
Compact the soil tightly around the pipe and up to the level of the slab. This process is essential to prevent any ground movement that could damage the pipe in the future.
Step 7: Reinforce the Slab
With the pipe repaired and the excavation filled, it’s time to reinforce the slab. Apply a layer of concrete mix over the area to create a new, solid slab. Ensure it’s evenly spread and level with the rest of the flooring. Once done, allow the concrete to cure according to the manufacturer’s instructions before proceeding.
Step 8: Waterproof the Area
After the concrete has fully cured, apply a waterproofing membrane to the slab’s surface. This step is crucial as it will help prevent future leaks. Follow the manufacturer’s instructions to apply the waterproofing layer properly. Allow the membrane to dry completely before proceeding to the next step.
Step 9: Restore the Flooring
Now that the slab is repaired and waterproofed, you can restore the flooring. Whether you have carpet, tiles, or any other type of flooring, reinstall them following the appropriate process. If necessary, consider hiring a professional to restore the flooring.
Step 10: Monitor for Future Leaks
Once all the repairs are complete, monitoring the area for any signs of future leaks is essential. Regularly inspect the area and watch for dampness, mold, or a sudden increase in your water bill, as these could be signs of a new leak. Addressing these issues early can help prevent severe damage or costly repairs in the future.
By following these ten easy steps, you can successfully repair a water leak under the slab and prevent potential damage to your home.
