VEVOR Non Woven Geotextile Fabric Under Gravel, 6x50FT 8OZ Driveway Fabric Landscape Fabric, Heavy Duty Weed Barrier Fabric, Ground Cover Weed Control Fabric, French Drains Drainage Fabric, Black

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.
