Hydraulic Cement for Leaky Basements

Using the right product for patching holes where water seep in will save you a trip back with a wet vac and a sump pump

There are two traits of hydraulic cement that make it idea for fixing leaky foundations, especially around waste pipes as seen in this video.

First, this type of cement will cure under water, which means that you don't have to dry out the leak before stopping it.

Second is that hydraulic cement expands as it cures, so it tightens up cracks and seals the gaps around pipes.
