Ideally, it is better to waterproof the outer walls of a basement during the construction of a building. Newer constructions require this procedure due to many requirements of state and local building codes, but many older homes may not have any exterior waterproofing. The exterior waterproofing prevents water from entering the basement or in tight spaces. Do not confuse this with interior waterproofing, which controls the water entering your basement.
The outer waterproofing prevents water from entering. A waterproof membrane or cover is placed to prevent water ingress. In connection with the above factor discussed, some homeowners may prefer exterior waterproofing to interior waterproofing based on the use of the basement. Interior waterproofing of the basement is considered a counteractive solution for when water has already entered the house, while exterior waterproofing is more of a preventive method of keeping basements dry in the future.
The exterior waterproofing of the basement is an expensive and complicated procedure in contrast to the waterproofing of the inner basement. It is an effective waterproofing method and a much less offensive alternative to outdoor waterproofing. After seeing the extensive excavation needed to waterproof from the outside of the basement, most homeowners opt for interior waterproofing options, such as an interior drainage system (IDS). Depending on how the outdoor waterproofing system is installed, which mostly comes from the outside of the basement, it is considered a less invasive form of waterproofing.
Another important part of outdoor waterproofing includes a waterproof membrane, which is installed around the foundation of your house to seal moisture so that concrete does not absorb it, cracks and allows leaks. There are different approaches to waterproofing, but a mortar is often needed to repair cracks or damage to the wall, and a tar or waterproofing membrane to protect the walls after repairs are done. However, the interior waterproofing will manage to keep the basement space dry by strategically using the waterproof membrane and drainage tiles. With waterproofing sheets and a French drainage system, your basement waterproofing system will work more effectively.
However, for minor basement waterproofing problems, many people are left with the interior waterproofing of the basement for economic reasons. The sump pump is also not entirely necessary for exterior waterproofing to keep water out, but it is a great way to prevent accumulated water from accumulating around the waterproofed base. In addition, for both types of waterproofing, it is important to note that the quality of the materials and the thoroughness of the installation contribute to the duration of the waterproofing.
