Exterior waterproofing is the best way for basement waterproofing. If you can keep the foundation from ever getting wet in the first place, that is great. But the truth is, you can’t keep it that way forever. The reasons are many, but it basically comes down to outside conditions. Anything you do out there is subject to changing extremes in weather, temperatures, soil conditions, pests, landscaping errors, and even your neighbor’s poor choices. Because it is constantly under assault by these factors, it is hard to warranty the home for any significant length of time. But in the short term, of course, a bone-dry foundation is best.
At Superior Waterproofing, we do interior waterproofing using a combination of methods, but most always, it involves drain tile, wall liners, and a sump pump. The water that was formerly pressurized behind the walls and under the floor now has an outlet. Think of your basement as a cardiovascular system in reverse. Rather than the heart (sump pump) pumping blood (water) to the veins (drain tile), it sucks it away, de-pressurizing your foundation in the process.
