Materials that are being used for basement waterproofing purpose and how those are used
Basement waterproofing materials can vary significantly in their forms and their uses. Some will be available to the public and some may only be available to the trade. Let’s assess the situation and see how we can apply it to your home.
The area in which you live is going to affect the amount of water around you. Materials that you can use will be influenced by the information you collect.
The first type of basement waterproofing materials that most people seem to be looking for are simple sealants. Their basement has previously had waterproofing done to it, so they are simply wanting to patch up some small damp portions. It is easy to find a sealant that can be used to treat the concrete once it has been poured, or indeed the mortar that is found in block walls. One type of sealant which is recommended for this is RadonSeal.
You need to treat the whole basement, walls and floor, otherwise it’s likely the water will simply find a way around the sealant. As it comes with a limited 20-year guarantee, this product is a practical option. Sealant is a potential problem to be aware of, (not only this one specifically, but with all sealants)basement waterproofing sealants only protect the inside of the basement. In other words, there could be lots of water pressing against and through whatever materials your cellar walls are made of.
Other avenues will need to be explored if you have cracks in the wall. Plaster wall can be can be repaired by replacing the plaster coating. All you need to do is chip away any loose material from around the crack and then fill the area back up with plaster.
One other option which is available is to use a stitching material. Metal staples are used to seal the cracks preventing or restricting movements. Cement that doesn’t shrink is used to fill in the cracks.
Gunite (a form of concrete) can be sprayed on bigger cracks in basement walls or floors. The special spraying equipment that is required can be rented. The mixture ratio must be correct for the spray to fill any cracks and leave a smooth finish. But it is still a good choice, because it adhere to most surfaces.
Ultimately, it must be remembered that basement waterproofing materials are not the final, only or the best solutions. You must see to it that there is minimal water around the basement perimeter.
