A crawl space is an empty, unfinished, small room inside an abode, usually beneath the first and second floor. The word ‘crawl’ is derived from the French ‘celoc’, meaning ‘crawler’. Essentially, the crawl space is designed to allow movement in the soil underneath the foundation of the building it is located in. The term ‘crawlspace’ is more commonly used in the construction industry, however, it is also used for other types of unfinished constructions where the foundation is not finished.
Moisture collects in the crawl spaces due to various reasons. A damp, closed area, may be created by the natural settling of the soil underneath the foundation of the building or may be created by the presence of damp walls or floors or plumbing pipes. A further cause of moisture accumulation is excess moisture accumulating in the structure’s roof system, which vents through the roof vents into the home through the attic. Regardless of the cause of moisture buildup, it is usually a good idea to make sure that the crawl spaces are kept dry. Otherwise, the problem can grow and eventually impact the structural integrity of the building.
There are a number of solutions that can be employed to keep crawl spaces dry. In general, the best solution is to ventilate the crawl spaces using good external venting techniques. For this, the home’s chimney and flue system should be kept free of debris. Also, the roof vents should be open and directed towards the outside of the house. Excess moisture from outdoors can build up in the attic and can potentially seep into the basement if proper ventilation is not employed.
If the foundation of the crawl space has already been built upon, then it may be difficult to install insulation between walls and basement floor, as walls and floors may be several feet high. However, by using vapor barriers at various points along the walls and floor, this problem can easily be solved. This will ensure that the basement remains dry and warm.
Crawl spaces also tend to be connected to main sewer lines. In such cases, it may be necessary to dig out the dirt from under the foundation and build a trench to run the pipes. In some cases, concrete and block may be required for this job. Once this is done, waterproofing should then be attempted. This can be done using a spray tube, which is able to seal surfaces with a foam-like substance.
The easiest way to seal surfaces in a crawl space before insulation is applied is to use a water-resistant paint. This method works best for basements located below the ground water level, as it prevents moisture from rising upward into the space. It will also prevent any mold or mildew from growing on walls and floors where insulation has not yet been applied. As walls and floors in such a space become damp, they tend to attract moisture from surrounding spaces and thus spread mold and mildew. A good system should therefore have a barrier that will cut off moisture from getting to the interior of the space.Type a message
