Building a retaining wall, out of brick and block. It’s fairly high, about 40″ at the highest point. I will be backfilling with lots of gravel and filter fabric. Place I ordered the brick from sent me a roll of “filter fabric” (that’s what I asked for). It says Poly “spunbonded” landscape fabric on the bag. That is it.
I have some other stuff from Home Depot that is commercial landscape fabric which the sign at the store specifically says is used when backfilling retaining walls. But of course these clowns are out of stock and nobody seems to know which truck is bringing it or when it will magically arrive.
The two fabrics appear quite different. The spunbonded stuff seems to be a lot more porous. So porous that it seems sediment would get through it. The stuff from HD seems pretty tight.
But then I found this online: This problem is largely avoided with the use of spunbonded fabrics, due to their almost microscopic opening size.
“The problem” is weeds shooting roots down through the fabric.
Anybody know if “spunbonded” fabric stops sediment? Or any other thoughts on which fabric I should go for?
MERC.

Try and find "GeoTec" or maybe it is spelled GeoTech or GeoTek
I think from Dupont, but not positive. It will come in much larger rolls, and widths, which sounds like might be what you want.
