Moisture in basements is a common problem with homeowners and because of moisture; it can be easy for cracks to form. It is very important to know how to fix basement crack and keep it from getting worse. A crack in your basement can cause decreased energy efficiency which is why you should fix the crack as soon as possible. We will list out a few solutions to this the problem and we will offer these techniques here.
Some of the most common locations that a basement crack might develop are under a basement window, along the middle of a long wall, and many times in the floor slab. Since the crack allows water to leak into the basement, repairing the crack needs to be repaired quickly.
One of the popular ways to fix basement cracks is with polyurethane foam. This foam works by injecting it into the crack while still in liquid form. While in the liquid form, it is easy to fill the crack with the foam with a steady, flowing line. After a few minutes, the foam starts to react to the moisture in the crack, and it will then start foaming.
As the foam expands, it will fill in the crack fully and will form a strong bond so water will not be able to penetrate through the crack. It will be able to withstand high ground level water that is mostly caused by heavy rain or melting snow.
Repairing the crack can also be done with patching, but is not as effective as the polyurethane foam. By patching the crack you are only repairing the crack from the inside, and that will still allow water to penetrate into the crack and eventually enter the basement.
The advantages of using polyurethane foam for filling in basement cracks is that it causes little mess than with other methods. It fills in the crack entirely from top to bottom, so there is no need for chiseling the foundation before filling in the crack, and the repair is done quickly, in about 2 hours.
Some polyurethane foam can be painted and can be sanded down to a smooth finish to make the crack virtually invisible which makes it more visual appealing. If you were to use this foam around cracks near a window, it is nice to know that you can still make the wall visually attractive and still be able to repair the crack.
The process of using polyurethane foam injections used to be done only by professional technicians but now it is widely used among average homeowners. The kits that they have available today is a great advantage for homeowners to stop water leaks on their own. The process can be done with a caulking gun so applying the foam to the cracks is easier.
You can also use epoxy for basement crack repair. These are used to help the concrete regain its former strength. This will stop the water leak, and reinforce the concrete. It works in much the same way as the polyurethane foam, in that it’s congealed with the water to fill the crack completely. Epoxies are also used in manholes and sewers, so they are very strong.
So if you happen to have a crack in your basement, do not worry, those are ways to fix it to keep your basement from turning into a swimming pool. Stop cracks from leaking and keep your basement dry the way it should be.
