The time-honored method of repairing basement-floor cracks is to widen them with a chisel or other tool and give them an inverted V shape; the purpose is to create a crack that will "lock in" the repair material. In place of regular patching cement or concrete, a product called hydraulic cement is often used.May 29, 2011
Can hydraulic cement be used on floors?
Once mixed with water, hydraulic cement sets and hardens in a matter of a few minutes. (Hot water quickens the setting time; cold water slows it down.) It can be used, not just on horizontal surfaces like floors, but also on vertical ones like basement walls. And it doesn't shrink, rust, or corrode.May 24, 2015

How do you use hydraulic cement in a basement?
Start applying the hydraulic cement at the top of the crack making your way down. Press firmly the paste into place, maintaining the same amount of pressure until the cement begins to harden and the leak is stopped. Do not blend excess water as this will cause bleeding and segregation.Nov 5, 2021
Can I use hydraulic cement to repair foundation crack?
The Wrong Way To Repair Concrete Cracks Do Not Use Hydraulic Cement – Disappointed, the homeowner will remove the caulk, chisel out the crack, and fill it with hydraulic cement.
