There’s no such thing as a waterproof basement. Special waterproof paint on the walls or coatings on basement floors may keep leaks from showing for now, but if the hydrostatic pressure in the earth around the foundation is great enough, water will find its way in. The key is to minimize the water that gets in and get it back out again before it affects your home.
Often, a basement is wet because it’s the next stop for rainwater after it leaves the roof. If gutters are clogged and overflowing or downspouts dump water too close to the house, and especially if the ground slopes toward the foundation, water is literally funneled into your basement. Gutter maintenance, downspout extensions and re-grading may go a long way toward a drier basement.
Inside the basement, digging a perimeter drain and installing a sump pump is the most common way to remove any water that comes up through the floor or through the walls. Since flooding can happen suddenly and is often accompanied by a power outage, some systems even include a second pump to handle extra volume and a third battery-powered backup pump.
