To repair a leaking concrete roof, you first need to find the leakage source, fill the cracks or holes that you find on the top with roof cement or mortar and leave it to dry out completely. After it has completely dried out, spread an elastomeric sealant on the corners, holes, cracks, and other areas that seem to be damaged. If you wish to reinforce the sealant, you can apply a second coating on the damaged parts the next day.

There are different ways you can repair water leaks in a concrete slab, but the ideal solution will depend on the leak’s location and how the house is constructed. To repair, you can do it by jamhamering the slab–digging into the pipe, and doing the repair. Or you can construct a new line through the attic or wall and leave the leaking line under the slab.

You can concretely repair water leaks by patching the holes, carrying out masonry waterproofing, or even attacking the source.
