If you are wondering what the best way to waterproof your home is, you need a perimeter drain and a sump pump to get the job done. First, do you have the proper dehumidification system? Second, do you have a water alarm? A water alarm will warn you if there is water in your basement. As well, your final price will depend on how complex the installation is. This is the part you'll attach to the PVC pipe. A local plumbing company may be able to help you with this process. These can cost a pretty penny, but they are well worth the investment, as they will help to ensure the safety of your family. It is then diverted away from your foundation and into the appropriate system.
