Drainage




The most reliable way to eliminate undesirable, free standing water is to install French drains with perforated pipes, filter fabric and gravel.


    In most homes, an external French drain is installed around the foundation walls before the foundation soil is backfilled. It's laid on the bottom of the excavated area, and a layer of drain rock is laid on top. Then filter fabric is then laid on top of the drain rock to keep fine sediments and particles from entering the pipe and clogging. Once the drain is installed, the area is backfilled and the system is left alone.
