Basement cracks usually occur when the soil around the foundation becomes compacted over time. The soil can move up and down and the compact soil can weaken the supporting structures of the house, causing them to eventually collapse. In some cases, cracks may appear in the basement walls as a result of drainage problems that are caused by silt. The most common type of basement wall crack is one that forms at the corner where the two walls meet; however, any crack in your basement walls can form.
Basement cracks can also be caused by the improper installation of plumbing, heating, cooling and electrical systems in your home. In order to fix most types of basement walls cracks, basement waterproofing contractors recommend the application of a chemical mixture called epoxy and a hardener, such as sodium silicate. Epoxy is made from pure epoxy resins while the hardener contains Portland cement, calcium bicarbonate or gypsum powder. These two ingredients bond together to form an impermeable surface, which prevents moisture and gases from penetrating the basement walls.
Basement floors should also be sealed in order to prevent leaks and to minimize damage due to earthquakes and heavy rains. Epoxy is a great choice for basement floor sealers because it is extremely effective at sealing cracks. Epoxy will not peel, rub off or otherwise bond with the floor or wall; thus it will not rust, deteriorate or become ineffective over time.
It is very important to repair basement walls and basement floors as soon as possible. Cracks in basement walls can lead to moisture absorption and structural damage to your home. If you notice water leaking into your home, it is a good idea to have your foundation walls repaired as soon as possible. Most repairs can be done quickly without disrupting your day-to-day life.
Most cracks are caused by soil expansion and contraction when there is a significant amount of water present. When soil expansion and contraction take place frequently, it can result in cracks. To solve this problem, most homeowners choose to fix cracked concrete floor panels using epoxy resins. Epoxy expands or contracts based on the difference in atmospheric pressure and relative humidity.
Most people choose to repair existing cracks in concrete by filling them with concrete mix. However, this type of repair will often lead to additional problems, such as swelling, cracking and water seepage. A better solution would be to allow the crack to fill in naturally with soil, after removing the top layer of soil. If the soil does not already have enough dissolved solids to fill the gap, then it will need to be mixed with concrete to add the necessary volume. This process will make sure that no additional soil is added, while ensuring that new cracks do not form in the future.
If you are planning to repair cracks in your basement without the use of epoxy resin, then you will need to purchase some chemicals to effectively crack the concrete without the use of an epoxy agent. These chemicals are available at any home improvement store. The two most popular chemicals used for basement repairs are acrylics and polymers. However, 40 psi is generally considered the strongest chemical, which will create a crack that is barely noticeable to the naked eye. If you are simply looking to make small cracks in a large area, then a lower strength chemical may be sufficient for your needs.
When purchasing basement flooring, you should also take into consideration basement wall cracking. Cracks in basement walls are caused by normal settling and will usually appear as tiny indentations. When these cracks get larger, they can often become larger holes in walls. Basement floors are usually constructed from masonry products such as concrete slabs or reinforced concrete. In these cases, normal settling will eventually cause cracks in concrete walls, and these gaps could allow water to seep through and enter your home, leading to health hazards.
