As a concrete contractor, I have a vested interest in how well the water on site is controlled. Underground water and runoff from rain and snow pose a threat both to the structural integrity of the foundations I build and to below-grade interior living space. Wet basements and cracked foundations are difficult to fix after the fact, but good perimeter drainage, both at grade and down at the footings, is a cheap and easy way to prevent problems. If you follow these rules of thumb for perimeter grading and drain tile, you’ll sleep easy knowing that the water control systems you buried today won’t bubble up into a callback tomorrow.
