    We better be. Keeps the aggregate from mixing, drains from clogging, and wall from failing. If your not, then your destined for failure sooner or later.

    It also keeps any sediment from flowing through the wall and staining your beautiful wall installation. I always recommend a very free flowing fabric to allow as much water through, but to contain the sediment.

    Actually, NCMA does not require fabric behind walls, but if an engineer specifies it you should always use a non woven fabric like the junky stuff from Home Cheapo. We use it about 50% of the time based on the application and type of infill material.

    cg could you give me the breakdown on which fabric types to use for each application. I happen to like the woven fabrics for driveway applications but you say on walls they are a not recomended.

    You should use a needle punched non woven Geotextile similar to "weed block fabric" (not the thin cheap crap with all the holes) The type that's usually gray and looks like a sheet of fiberglass. These fabrics resemble felt and provide planar water flow. They are commonly known as filter fabrics (although woven monofilament filtration fabrics exist). Typical applications for non-woven geotextiles include aggregate drains, asphalt pavement overlays, and erosion control.

    Below, are a photos of non-woven filter fabric (good for walls and drainage)
    and woven- good for soil wraps, and base stabilization (under the base for pavers)

    What happens to the wall after the fabric clogs up from all that sediment you are keeping from coming through your wall?
