French Drain Question

French Drain Question

French Drain Question

(OP)
Hi Folks,
I just built a french drain behind my garage. Instead of filling it with gravel I filled it with concrete sand after laying my pipe with sediment filter. Do you recommend that I cover sand with soil and plant grass seed, or just leave the sand exposed?
Thank you,
Jim  

RE: French Drain Question

In the end either way will work.  If you don't have a surface water problem, cover with topsoil and plant.  If you have a surface water problem, the sand will drain quicker without topsoil.

Thanks Geopavetraffic,
I appreciate the helpful advice. Would you recommend me channelling a gutter downspout into this trench?
Jim

RE: French Drain Question

If you can extend the downspout to daylight, it would be better to keep that water in a pipe.  You cold place the downspout pipe in the same trench.  Once it is away from the house, you could use perforated pipe.
