Basement Floor Crack Video
VIDEO SUMMARY
Before installing flooring on your concrete floor, you have to make sure it is smooth and crack free. You will need a floor leveling or crack filling compound. There are several that are just mixed with water and cement based so they are very sticky. Read the instructions on the package for preparation. Most will require that the floor be clean and free of loose concrete. Take a scraper and remove any high spots. Clean the area with a sponge and water. Let the floor slightly wet, this will help the floor crack compound stick.
Mix a small amount of filler. They have a fast setting time, often 3 - 4 minutes. If you mix too much, it will set up before you can use it. Apply the material with a large broad knife. Try to get it as smooth as possible. A second coat might be required.
Get up any excess so when it dries, it will not stick up through the floor covering. Also, clean your tools as soon as possible. If the crack filler dries on the tools, you might have to throw them away.

At my lake cabin, I had indoor/outdoor carpet removed from my basement
floor. I used a sander and sanded it smooth then applied garage apoxy
paint that has specks you throw on top of the wet paint. After a rain I
noticed clear water sitting on the freshly painted floor. I cleaned it up
and it happened again after another rain. I noticed a hairline crack where
the puddle was. What do I do? The apoxy paint is already on the floor!

Hey, So happy to have found your site. I am the building manager and handy
man for the building I live in and need to address basement floor leaking.
It's an old house and leaks significantly when we have noreasters. I have
been looking up products and most address foundation or wall leaks. What is
the best product for floor and wall leaks? I have diverted the gutters and
spouts away from the foundation and it worked for a while. Not anymore. It
is contributing to mold production. Need help.

I am having a new home built and the basement floor is cracked in several
places. One goes the entire width of the basement. Can this cause me
problems in the future, can it be repaired permanently or is it a non
issue.

My home was new when I moved in 18 yrs. ago. I have a full basement that
has been completely dry until recently. I had clogged pipes running off of
my downspouts that I just had replaced. Prior to this, the rain water was
running off the sides of my gutters and down beside the foundation of my
home. We also had a very wet fall and winter here. As a result, I started
noticing several cracks in my basement floor. One had a small stream of
water with a sudsy effect on the side which I originally thought was cat
urine. I now know it was water coming through the concrete flooring. Since
replacing the hoses attached to the down-spouts that take the rain water
away from my home, I have not noticed anymore water in the base-ment. My
basement floor had a cement paint over it that has been there forever.
What should I do now to repair the cracks and what product should I get.
Also, can I repaint over the concrete floor afterwards. Please respond
asap.
