Many homeowners consider exterior waterproofing to be one of the most expensive/ labor-intensive home improvement projects they ever do. In some cases, projects that homeowners thought were small explode into costly and time-consuming ordeals. This is due to the excavation, which also leaves your landscape in need of repair. Exterior waterproofing that is done by the builder of the home during construction is the easiest, cheapest and most effective.
However sometimes even that is only temporary. Some builders use a tar-type sealant, which cracks over time allowing water to seep in. Some homes are waterproofed by applying a vinyl or plastic material over the block, but when the dampness get onto the walls the material will eventually not stick any longer.
If you have water flowing down hill toward your basement or foundation, you will need to change the slope of your landscaping by having someone come in with a back hoe and move the dirt to make it level or slope away from your house
You may find that your down spouts need to be extended. The water should run out the end of the spout at least five feet away form the foundation. This is a simple fix.
If your home is located on a hill, then gravity will favor you. However, if you are on a level ground, your next options are a French drain or a drain tile. The drain tile if placed alongside the foundation footer, not on top of it. Fitted pipes can be used to get around corners. Install the drainpipe and cover it with gravel to the foundation footer.
It is important to waterproof your basement to prevent water from causing dampness and destruction to your basement and property. However, if this does not work, consider hiring a professional plumber to do the work professionally and competently. Apart from having the right tools, skills and experience to get the job done, another advantage of hiring professional plumbers is that they also adhere to strict industry standards.
