VEVOR 4FTx300FT Premium Heavy Duty Weed Barrier Landscape Fabric, 3.2OZ Woven Geotextile Fabric Under Gravel, High Permeability for Weed Blocker Weed Mat, Driveway Fabric, Weed Control Garden Cloth

I’m not sure how I would measure that at home. It’s pretty thick almost like a tarp material.

In my application as landscape underlayment, this product is covered with crushed granite, thus not exposed to direct UV rays. In one small area, a section of about a 6 inches by 4 feet was purposely left uncovered since June 2024. It does not appear to have suffered much from UV in the 8 months of Phoenix sun exposure. Not sure how a large piece would be effected. It is my understanding that intense heat causes it to shrink.

I can't imagine just putting the fabric down and not covering it with mulch or in my case tons of gravel. So, I don't think the durability of the fabric to UV rays is an issue. So, I don't know about the durability of the fabric to UV rays. Sorry.

I don’t know about Sealtech but I used it under 6 Ton of pea gravel. It is very heavy duty and could not see thru it. Hope this helps!

This is an excellent product very thick and will survive for years

No

I don’t know about yhe Sealtech but you can not see thru the Vevor. It was easy to use and worked great.

What difference does it make. you're putting it on the ground and covering it

Can’t see through this material. It’s pretty heavy duty and is a weave type material similar.

No. It's pretty heavy duty stuff.

I don't see the point in this but yes you can and I highly recommend wire mesh reinforcement at least.

Not sure why you'd want to pour concrete over this? It is for weed control and allows moisture to get into the soil and helps stabilize the soil some.

I don’t see why not. Not much different than poring over a plastic sheet moisture barrier except don’t expect it to act like a moisture barrier

This is giving the weight as amount of material to expect per square metre/yard. It's basically a measure of effectiveness. A heavier material may filter better, or slow down liquid flow. You'd have to look up and compare performance per particulars. The item appears to be groundcloth over the drainage around the base of a foundation,in which case it would prevent perforated pipe from being clogged by sand and silt.

8oz is per square yard (3ft X 3ft) And 226.8g is per square meter. Same values, just different units (oz vs grams; yard vs meter)
