6oz versus 8oz underlayment

[zerogravitybambi]

Hi all.

I'm looking to geotextile to protect my liner from a top layer of mortared stone. While shopping, I came across an 8oz geotextile. I think of 6oz as being industry-standard...

Based off the inspiration photos below...should I go with 8oz? I have no concept of how protective 6oz or 8oz will be, even having watched countless videos. Worth noting, only the walls/sides will be the mortared stone. The seats and bottom will be flagstone and smaller gravel, like the attached photo below (with the blue tone to it, with words in the frame). Stones are 3-5" thick and ~9" in length, KS garden edging.

Seems like 6oz will be fine but thought I'd poll before I pulled the trigger.

TYIA!

6 oz you cut cut with a utility knife and only need to replace the blade 3 times in the course of a days work. 8oz you will need to replace the blade after a 39 feet cut. . Night and day. I will only use 8 oz unless I have nothing but sand going against the liner.
8 oz is good stuff but if you have Sharpe granite lots of roots etc. You can step up even higher to 10 orc12 oz those are crazy tough

Thanks for the clear response! I’ll order 8oz today.

i strongly recommend using sheers such as these though the two blades coming at the fabric from both sides works much better. and can be used like a utility knife. they do not need to be offsets grips but i could not find the standard https://www.amazon.com/Wiss-Shear-Offset-Right-Hand-Titanium/dp/B07YD62263/ref=sr_1_2?dib=eyJ2IjoiMSJ9.abUXLXmuK8iUmtfl9uAog0fbuJJQGvbfKQq5oO1v9wx6j4jMiU_8FujxTu33__FXSByQ1jnBzNdD2sqOGEpiO0VfSrGeGoR00XDQ0rssTc9JWTI57-MsWB9SeUmktwX2AASlXKav9GtxBjyayT2wSP8cX11bJpkh2AOYwR98n7MajqjnEnVq87G4D1Wg1T38n7K2y1qol82Rt0YcShyW8pdo0ESICCk0xvilxYPDFxrtsEeBIg2qtW-xYAXl0UX1GksooHP-f1gL71UVPzWzxHhkz0ekd0NRe7JhZE-5Wsk.VDFITX_R5UOtFEojIIqvGSkpfJKfYzp3n5rsuJmLFMc&dib_tag=se&keywords=weiss+shears&qid=1726417295&sr=8-2&th=1
