rock landscape fabric

Most rock/landscape fabrics are made from polypropylene (PP) geotextile. They are offered in both woven and non‑woven (needle‑punched) polypropylene constructions.

Common weights listed include about 1.8 oz, 5.8 oz, 6 oz and 8 oz per square yard. Some product listings also specify strength figures such as tensile strength around 350 N and a load capacity listed at 440 N.

These geotextiles are permeable and designed to let water pass through while filtering soil. They help prevent pooling and are suitable for drainage applications such as French drains.

Several descriptions state the fabrics can withstand heavy loads, gravel and vehicle traffic. Some rolls list specific strength figures such as a tensile strength around 350 N and a load capacity of 440 N.

They’re placed as an underlayment beneath gravel or stone to stabilize the base, prevent soil mixing, and help suppress weeds while allowing drainage. Several listings explicitly state suitability for gravel, stone and driveway installations.
