French Drain

Our lake lot slopes from the front to the back creating a potential drainage problem in the front.  In addition to waterproofing, a french drain is installed to carry off any water build up away from the foundation.  The first picture shows a filter sock being placed over the drain pipe to keep sand and silt from plugging up the drain pipe.  The second picture shows the drain pipe being laid on footing, and the third shows the  gravel which is back filled to filter and accelerate drainage into the pipe.
