When we have cracks and crevices in our houses and other places we need to fill and seal those cracks, this process is called injection waterproofing. The material that is used for filling most often made from a polyurethane compound. Usually, this compound is lightweight and when this is applied to a surface, this expands up to twice its original size. There are many non-toxic and environmentally safe products that are used in injection waterproofing. You can easily find these products at home improvement stores nationwide.

What is Use of Injection Waterproofing?

Injection waterproofing is mainly used to repair foundation cracks. Polyurethane injection is used to seal the openings in most foundation cracks. In some smaller cracks, it is quite difficult to evenly inject the compound. In this case, a sealant can be used instead of the compound. There are two types of injection waterproofing compounds: one is single caulking style cartridges and the other is the dual side-by-side cartridge systems. Both of the methods are easy to pump and are injected manually.

Just keep the area dry before using an injection waterproofing method. The area where you want to apply this waterproofing method should be clean and dry, if you have any flowing water in that area then temporarily block it. In the case of water flowing through a hole, you can use candle wax, modeling clay, and plumber’s putty to caulk the hole temporarily. A flexible hose is attached to the injector nozzle for narrow cracks or such places where you can’t reach easily.

How Can You Do Injection Waterproofing?
