I'm putting in a 1'x1' french drain around the side of my house, and I'm
wondering what would be the best material would be to cover the top few
inches of the trench. The soil around here is mostly clay, and it seems
like a better idea not to use clay to fill in the top with, as I'd like
to allow for as much drainage in through the top as possible.

I plan on using 4" perforated flexible pipe, wrapped in a fabric sock,
with the remainder of the trench being filled to within 3 inches of
ground level with some leftover driveway gravel. I might use fabric
around the gravel as well.

My guy used a layer of straw and then some coarse gravel over that
before filling back in with topsoil that has a lot of clay in it.

Theres a sock that fits over the pipe.

I do have to ask are yu trying to fix a water problem in your
basement?

If you are surface control will likely fail. Theres no harm in trying
but you need to know.

If its water leaking in basement a interir french drain is a far
better choice
