TERRA is a non-woven, needle-punched geotextile available in 4, 6, and 8 oz weights. The felt-like mat is built to filter and let water flow through its thickness - exactly what French drains, retaining wall backfill, driveways, and erosion control need.
TERRA is a felt-like mat of polypropylene fibers punched together, so water moves through the thickness of the fabric instead of across it. That is what drainage and filtration need, and it is why a woven weed barrier is the wrong tool for the job.
Water passes through the body of the fabric while silt and soil fines are held back, so a drain keeps draining instead of silting up.
4 oz for simple drainage and separation, 6 oz for French drains and retaining wall backfill, 8 oz for road base and heavy stabilization.
Real ASTM-tested attributes for TERRA 8 oz. The 4 oz and 6 oz weights share the same needle-punched construction at lower mass; ask us for their full data sheets.
Use the right fabric for the right ground condition. For weed control under mulch choose SHIELD; for load-bearing gravel and pavers choose XBAR.
Wrap the trench so the stone keeps draining and the pipe stays clear.
Keeps aggregate and subgrade apart so the base does not disappear into the soil.
Behind the wall, filtering backfill so water leaves and fines stay put.
Stabilizes the base layer under gravel drives and access roads.
The needle-punched mat drains through its thickness, which is exactly what a French drain or wall backfill needs.
Holds silt and soil out of your stone so water keeps moving through the drain.
Step up from 4 oz to 8 oz as the load and filtration demands grow, with the same construction throughout.
500 lb CBR puncture resistance at 8 oz, so angular stone and compaction do not open it up.
The felt-like mat drapes into trenches and around pipe instead of bridging and tenting.

Lighter 4 oz suits simple drainage and separation; 6 oz is a versatile middle ground for French drains and walls; 8 oz handles heavier separation and road base. Match the weight to the load and how much filtration the job demands.
They are different tools. TERRA geotextile is non-woven and engineered for drainage, filtration, and soil separation, while a woven landscape fabric like SHIELD is built for weed control. Choose by the job: water movement versus weed suppression.
