Clay holds water against the footing for a week. Drain tile is what finally moves it.
Griffin has more basements than the areas south of it and the heaviest clay we work in, which is why interior drain tile is one of the more common installs we do in Spalding County.
The clay holds water against the footing for a week or more after rain, so the pressure on the wall and under the slab is sustained for weeks. A stone-packed drain converts that week of standing water into a few hours of drainage.
The elevation and rolling ground work in your favor for the discharge. On most Griffin lots we can run a gravity line downhill to daylight, which means no pump, no power draw and nothing to maintain beyond keeping the outlet clear.
Every Griffin home gets the same basement french drains scope, and the written price says exactly what that covers.
