Waterproofing companies like Clint Miller Exterminating place an impervious barrier on foundations, roofs and walls when it’s needed. When your house was built, it should have had a barrier, but over time, it may erode, which causes water to seep into crawl spaces, attics and basements. If your crawlspace or basement leaks or gets damp, the dampness will get into your house. This could cause mold to form and wood to rot.
Basement waterproofing and permanent basement waterproofing are two types of waterproofing you can do to protect your investment. Additional types of waterproofing include foundation waterproofing, bathroom and kitchen waterproofing, terrace waterproofing and swimming pool waterproofing.
Foundation waterproofing, whether for basements or crawlspaces, is important for the longevity of your home. You not only have to worry about leaks when it rains, but you also have to keep the moisture from the soil out of the basement or crawlspace. Eventually, if the basement or crawlspace doesn’t have the proper waterproofing, the wall becomes waterlogged and could start to crumble.
In addition to putting waterproofing on the basement or crawlspace walls, you should put in a French drain if the water problem is bad enough. A French drain is a natural drain that is filled with gravel and sand and then topped with topsoil and grass. The water goes down into the drain and dumps out where it can’t hurt buildings or landscaping.
A French drain may be just long enough to get the water away from the house, or it could be long enough to go to a different section of the yard. Many people use a French drain to direct water to a low part of the yard and plant water-loving plants in the area.
Since concrete is porous, it needs to have waterproofing materials on it to prevent it from becoming waterlogged and leaking. The best way to do this is to put waterproofing materials on the outside – against the dirt. This is known as waterproofing the positive side. If you put the waterproofing on inside the basement or crawlspace, you are waterproofing from the negative side. While that does help, it’s not the best, though in some cases, it may be the only solution. Waterproofing materials include:
Sheet membrane systems: A membrane made from polymer materials is integrated with asphalt to form an elastic material in the form of a sheet. The sheets are self-adhering and self-healing, and are resistant to acidic soils.
Liquid membranes: These types of waterproofing material is painted on with a brush, sprayed on or put on the concrete with a squeegee or trowel. They have polymeric asphalt or urethane in them. Liquid membranes are usually applied to the positive side of concrete that is cured.
Admixtures: Chemicals are added to the concrete to make the concrete waterproof. They’re added at the plant when the concrete is mixed. The concrete doesn’t need a water barrier since it becomes waterproof once it cures.
Crystalline admixtures: This powder causes water to grow crystals in the concrete, which blocks water from seeping through the concrete. These are also added at the plant when it mixes the concrete.
If you notice that your basement or crawlspace walls are damp, or you have leaks when it rains hard, contact Clint Miller Exterminating to make an appointment to discuss waterproofing your basement or crawlspace.
