how to replace hydraulic piston seals How to Seal a Leaking Concrete Wall
Concrete walls sometimes only leak regularly, such as after heavy rain or during melting snow.However, some walls spray water through the openings in the concrete.Most leaks occur on walls below grade or below ground level, such as those used in the home base.Correct patch or sealant depending on the type of leak.Steel bars installed on concrete walls are a potential source of leakage.When concrete is cured during home construction, the rod helps to keep the concrete stable.In the end, the builder removed the rod but left the hole.As time goes on, cracks and gaps will also appear in the concrete.Some of them may even be small and you can hardly detect them.Any one of these openings is a potential source of water.You can repair any obvious holes or cracks with hydraulic cement.This product is usually sold as a powder and you have to mix with water before applying it, although some brands are in putty --Just like the form that is ready to be inserted in place.You can even use hydraulic cement when the concrete wall leaks, which allows you to deal with the problem when it happens.Slightly expand the opening by removing any loose concrete material.Then mix a batch of hydraulic cement as indicated on the package and put it in place.Hydraulic cement is fast to cure.Only mix what you can apply for in three minutes or less.Concrete is a porous material when fully cured.It can also develop small holes as a capillary for water transmission.Seal the entire concrete wall with waterproof masonry products.Apply a generous coating of this material on the wall and work the product in all directions to completely seal any fine holes.This material is very thick, much thicker than latex paint, but on a regular brush.Once the waterproof masonry product is dry, a waterproof film will be formed to prevent water from leaking from the wall.Find water sources that penetrate the concrete walls.Check if the trench or downpipe leaks to the top-grade wall.Make sure the ground around the building is away from the structure so that the water can go downhill and away from the base.Install the sink, or make sure that the sink that is already in place is clean and does not cause a backup of the water.Install a downpipe that draws water from a few feet away from the foundation.
