FRENCH DRAIN GOING THROUGH TREE ROOTS
French Drain Installation this week was a little more difficult than normal. Many times the route that a Perforated French Drain Pipe must travel to its exit point is not very easy from an installation point of view. French Drains may have to travel through tree roots, (big ones) under sidewalks, through retaining walls, around swing sets or dog kennels or Mom’s Prize Rose Bush. The 4 inch French Drain we installed this week was in Oklahoma City south of 23rd in an old part of town where all the houses were old 2 or 3 story homes with lots of huge Elm Trees. The Elm Tree in Question actually was just an old stump that had been topped out but not completely removed. They left the roots just for us! The roots were growing into the homes foundation and were right in the way of the path of the French Drain. Forty feet of solid Elm Roots and 4 chain-saw blades later CMG was successful in running a new French Drain through a tree stump. Yuck! “Well you gotta do what you gotta do!”
A little info about French Drain Pipe and Tree Roots. Normally tree roots don’t seek out and penetrate French Drain Pipe. Tree roots seek moisture and residual water that may stay inside Solid Drain Pipe. French Drain Pipe is perforated. Water that does not reach the exit point of the French Drain will seep out of the Pipe into the surrounding dirt. Solid Drain Pipe that is used with Surface Drains can be penetrated and eventually clogged by roots if the pipe does not have good slope or “Fall”. If the solid pipe does not drain well and has residual water, tree roots will seek it out.
