Purpose: Hydraulic Cement is a blend of hydraulic cement and proprietary admixtures used for plugging and stopping water or fluid leaks in concrete structures and masonry walls. When mixed to a thick consistency and hand-formed, Hydraulic Cement will set in 3-5 minutes to seal out water.
When should hydraulic cement not be used?
Once mixed, the hydraulic cement only remains workable for 10 to 15 minutes. Will not work on frozen surfaces or if the temperature will drop dramatically within 48 hours. Avoid using it when the temperature is below 40 degrees Fahrenheit.
Will hydraulic cement bond to concrete?
However, hydraulic cement has a weak bond with concrete, which is the reason the crack needs an inverted V-groove to hold it in. Additionally, hydraulic cement is very rigid. As concrete continuously moves, shrinks and expands, the rigid “rod” will loosen.
When should you use hydraulic cement?
Hydraulic cement is only suggested where the concrete mix is going to be used within 10-15 min of the time period. This cement is capable to provide strength to structures that are in contact with water. Therefore, hydraulic cement is used for concrete structures which are highly durable in nature.
What is the difference between hydraulic cement and regular cement?
The major difference between hydraulic and non-hydraulic cement is the hardening process. Hydraulic cement can harden while in contact with water. Non-hydraulic cement needs dry conditions to strengthen.
Is hydraulic cement stronger than concrete?
Hydraulic Cement is Weak – Cement of any kind, by itself, has little structural strength – that’s why it’s most often combined with sand and aggregate to form concrete, a very strong material.
How long does it take hydraulic cement to dry?
Mix only enough for immediate use, because DRYLOK Fast Plug sets in 3-5 minutes. Cannot be reworked once it has set. SET TIME: 3-5 minutes Note: Maximum cure and dry time will be prolonged when slightly humid and when damp, cool conditions prevail.
Can I use hydraulic cement as grout?
Hydraulic-Cement Grouting This type of grouting tends to be less expensive than chemical grouts, and is well suited for large volume applications. This is normally the type of grout preferred for sealing cracks in foundations. To use hydraulic-cement grouting, first clean the cracks that are to be sealed.
Can you use hydraulic cement to repair foundation crack?
Hydraulic cement comes in handy when basement and foundation cracks are repaired from the outside of the house, as may be the preference of a homeowner. In such a scenario, professionals must dig up the earth around the cracked area and then clean off the excess dirt from the foundation wall.

Can you use hydraulic cement on wet surfaces?
When you are prepared to apply the cement, mix up a small amount with water in a bucket. Before the application, use a spray bottle or a bucket of water to dampen the crack as cement will adhere better to the wet surface. Next, apply a layer of hydraulic cement into the crack in such a way that the cement is about .
Why cement is called hydraulic cement?
A type of cement that sets very quickly and hardens with the addition of water to the finely ground cement is called hydraulic cement . This type of cement is especially good for structures that are constantly in contact with water because it is impermeable to water.
What is another name for hydraulic cement?
Similar words for hydraulic cement: Portland cement.
Is hydraulic cement the same as non shrink grout?
Non-shrink grout is a hydraulic cement grout that, when hardened under stipulated test conditions, does not shrink, so its final volume is greater than or equal to the original installed volume. It is often used as a transfer medium between load-bearing members.
Does hydraulic cement expire?
Shelf life of unopened containers, when stored in a dry facility, is 12 months.
Can you skim coat a wall with hydraulic cement?
Skim Coat is a smooth, sand-free, hydraulic cement-based material used under flooring for patching and skim coating on interior and exterior projects. Apply from featheredge to 1″ thick.
Can I use hydraulic cement instead of mortar?
A special type of cement, similar to mortar and easy to use, hydraulic cement is handy for preventing water from seeping through your foundation and into the basement. 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.
Can you sand hydraulic cement?
Patches of cement are often uneven and stand out from the rest of foundational walls, especially if cracks in the original walls necessitated the repair. It is possible to sand the patched areas of the walls so that they sit on an even level with the use of an angle grinder.
Can hydraulic cement be used over paint?
Hydraulic cement is generally used for patching water-related cracks and holes in concrete, but it also makes a good patching alternative for any type of cement repair. Although the chemical properties are slightly different than genuine cement, it can be painted over just like regular cement.
How much water do I add to hydraulic cement?
Blend 4 – 4 1/2 parts Water-Stop Cement to 1 part water, by weight. Ingredients should be mixed to form a heavy putty consistency. Do not mix more material than can be used in 2 – 3 minutes.
